Split into
Tile shape
Keeps faces and text clear of the edge when a platform re-crops the tile.
Output
Extra picture past every cut, so printed sheets can be glued edge over edge.
Cut on exact edges, or wherever you drag
Set a column and row count, name a fixed tile size in pixels, or take hold of the cuts and drag them where you want them. Every cut is a rounded cumulative position rather than a rounded tile width, so a 1000px picture divided three ways loses no pixel and the pieces still butt together.
16 controls, not a fixed result
Set columns, rows, tile width and tile height, choose how to cut, edge left over and shape. 16 controls in all. Every change redraws over your own photograph, in this page's own document.
Part of the draw & transfer set
The picture you have open here is ready for grid drawing tool, rectangular grid maker and custom grid maker, and 10 more in the group — nothing to re-upload, because nothing was uploaded.
PNG, JPG or WebP at the source resolution
Tiles come out at the size they were cut from the original, never at screen size. Save one on its own, take the set as a ZIP with an assembly sheet inside it, or print the lot as a multi-page PDF with trim marks.
- 100% free
- No signup

- Nothing is uploaded
Choose how many columns and rows, see every tile at the size it will be saved, and take them one at a time or all at once as a ZIP. The picture is decoded and cut in this page and never leaves your machine. The same app carries the 82 composition overlays, so a tile can go straight under a grid without leaving the browser.

What is an image splitter?
An image splitter divides one picture into a grid of separate image files. Set the number of columns and rows, and each cell becomes its own file that can be saved on its own or downloaded with the rest as a ZIP. Grid Maker Pro does the cutting inside your browser, so the picture is never uploaded and there is no limit on how many times you use it.
How to split an image into a grid
One picture, a grid of cells, and a folder of numbered tiles that reassemble in the right order. The splitting happens in your browser, so the original never leaves it.
Drop the picture onto the page
Drag a file onto the panel above or click to choose one. Your browser decodes it locally — there is no upload step, so a large photograph is ready as fast as your disk can read it.
JPG · PNG · GIF · WEBP
Set the columns and rows
Type the numbers or pick a preset. The tiles are cut immediately, so you can see whether a 3×3 lands where you want before committing to it.
Columns · Rows · Cell labels (A1, B2…)
Take the tiles
Click any single tile to save it, or download all of them as a ZIP. Files are named in reading order with a padded number, so they sort correctly in every file manager.
PNG · JPG · PDF · SVG · up to 600 DPI
Three steps, about a minute. No signup, no upload.
What the Image Splitter does
No pixel is lost at the seams
The image splitter computes tile edges cumulatively rather than by multiplying a rounded tile width, so the tiles differ by at most one pixel and together cover the original exactly.
All of them, in one archive
The ZIP is assembled in the page from the tiles you can already see. Nothing is queued, emailed or held on a server waiting for you to come back for it.
Lossless output
Tiles are written as PNG, so a screenshot or a piece of flat-colour artwork comes out of the splitter exactly as it went in — no second round of JPEG artefacts.
No queue, no size cap
There is no server doing the work, so there is nothing to queue behind and no per-file limit beyond what your own browser can hold in memory.
The picture never leaves
Private photographs, unreleased artwork and client material can all be split here, because the file is read by your own browser and there is no endpoint to send it to.
Named so they sort
Files come out numbered with a leading zero, which is the difference between tiles that sort 1, 2, 3, 10 and tiles that sort 1, 10, 2, 3.

Who an image splitter is for: the people who put the tiles back together
How an image splitter works — Why splitting an image is a geometry problem before it is a file problem
An image splitter cuts a rectangle into equal pieces, which sounds like the simplest operation in imaging and is where most splitters quietly go wrong. The same arithmetic decides every one of the 82 composition overlays that divides a frame into cells. It is the same division the rectangular grid overlay draws on screen, and the basic drawing grids set out why the cell count matters. It is the same division the rectangular grid overlay draws on screen, and the basic drawing grids set out why the cell count matters. The error is invisible in a preview and obvious in the result, and it comes from rounding in the wrong place.
The naive method is to compute one tile width — the image width divided by the column count — round it to a whole number of pixels, and then cut every tile at that width. For an image whose width divides evenly this is correct. For every other image it is not: a 1000-pixel-wide picture cut into three gives a tile width of 333.33, which rounds to 333, and three tiles of 333 pixels account for 999. One column of pixels down the right edge belongs to no tile at all.
A single missing column is easy to dismiss. It stops being easy when the tiles are reassembled — in an Instagram feed, in a print layout, as a puzzle — because the seam is where the eye goes. And the error scales: a 4000-pixel image cut into seven loses up to six columns, which is a visible strip.
Computing the edges, not the widths
The correct method computes the EDGES rather than the widths. Edge i sits at round(width × i ÷ columns), and each tile runs from one edge to the next. The tiles are then not all identical — some are one pixel wider than others — but their union is the original image exactly, with no gap and no overlap. That is the property that matters, and it is the one this tool implements.
Choosing the output format
The second decision is the output format. A splitter that writes JPEG is putting every tile through a second lossy encode, on top of whatever the source already went through. For a photograph destined for social media that may be acceptable; for a screenshot, a diagram, a piece of line art or anything with flat colour it produces visible ringing along every edge. PNG is lossless, and for the material people most often split — screenshots, artwork, maps — it is also frequently smaller.
Where the work happens
The third is where the work happens. Most splitters upload the picture, cut it on a server and hand back a download. That is a reasonable engineering choice and a poor privacy one: the file now exists on someone else's disk, subject to their retention policy, for a task that a browser has been able to do unaided since the canvas element shipped. Doing it locally also removes the upload wait, which for a large photograph is most of the elapsed time.
Gaps, bleed and reassembly
There is a fourth decision that only shows up once the tiles are somewhere else, and it is about ORDER. A three-by-three cut produces nine files, and the order they should be used in depends entirely on what they are for. Tiled printing wants reading order, left to right and top to bottom, because that is how the sheets get laid on the table. A social feed wants the reverse of reading order, because the platform puts the newest post first and the grid assembles itself backwards as you upload. A puzzle wants no order at all. A splitter that hard-codes one of these and calls it correct is making a decision it has no information to make, which is why the numbering here changes with the page you are on rather than with the tool.
Aspect ratio is worth a sentence too, because it is the commonest disappointment. Splitting a 3:2 photograph into a 3x3 gives nine tiles that are each 3:2 — not nine squares. If the destination wants squares, the crop has to happen BEFORE the split, not after, or the nine tiles will each be cropped differently and the grid will not line up. The tool shows the pixel dimensions of a tile as soon as the division changes, precisely so that mismatch is visible in the second before it becomes nine files.
Finally, a practical note about very large pictures. Because the work happens in the browser, the ceiling is the device's memory rather than an upload limit, and those two ceilings sit in different places. A phone will handle a 12-megapixel photograph into a 3x3 without complaint and may struggle with the same photograph into a 20x20, because four hundred canvases exist at once. Splitting in two passes — coarse, then split a tile again — costs nothing in quality, since every cut is lossless.
Naming the tiles
The last is naming. Tiles are almost always reassembled in order by something — a person dragging them into a feed, a script globbing a directory — and unpadded numbers sort lexicographically, so tile 10 lands between tile 1 and tile 2. Padding the number is a one-line decision that saves a confusing five minutes at the other end.
None of this is difficult. It is simply the difference between a tool that produces tiles and a tool that produces the right tiles, and the difference only shows up after the pieces have been put back together.
Where an image splitter gets used
Feed grids are the obvious one, but the bigger use here is print: a poster bigger than the printer gets split into pages, taped, and traced. Losing a pixel column per seam is exactly what you see when the tape line does not match.
Splitting a screenshot for a bug report used to mean uploading a picture of an unreleased product to a random site. Doing it in the browser removed a policy conversation entirely.
Puzzle and tile projects need lossless output. One pass of JPEG on a piece of flat-colour artwork and every tile has a halo along its edge.
Tiled printing is the unglamorous case and the one that exposes every shortcut. A banner split across twelve A4 sheets has eleven seams, and each one is a place a rounding error shows as a white hairline after the sheets are taped. Getting the edges right is not a nicety there — it is the difference between a usable print and an afternoon wasted.
Image splitter: frequently asked questions
The geometry
What is an image splitter?
An image splitter cuts one picture into a grid of separate image files. You choose how many columns and rows, and each cell of that grid becomes its own file — nine files from a 3×3, eighteen from a 3×6.
What format are the tiles saved in?
PNG, which is lossless. That matters most for screenshots, diagrams and flat-colour artwork, where a second pass of JPEG compression puts visible artefacts along every edge. Photographs come out unchanged too, just in a larger file.
Will the tiles fit back together exactly?
Yes. Tile boundaries are computed as cumulative edge positions rather than by repeating a rounded tile width, so the tiles cover the original with no gap and no overlap. Some tiles may be one pixel wider than others, which is the correct result rather than a defect.
Can I split an image for tiled printing across several sheets?
Yes. Choose the number of sheets across and down — three by four for twelve A4 pages, for example — and print the tiles at the same scale. Because the tile edges are computed cumulatively, the printed sheets line up along every seam with no missing strip, which is the failure that ruins a taped-together print.
Can I split an image for an Instagram grid?
Yes, and there is a page set up for it. The Instagram grid maker uses the same splitter with feed-shaped presets and numbers the tiles in upload order, because Instagram shows the newest post first and a feed grid has to be posted in reverse.
Why are some tiles one pixel bigger than others?
Because the picture's dimensions rarely divide evenly by the number of tiles, and the remainder has to go somewhere. Distributing it means every pixel of the original ends up in exactly one tile. Tiles of identical size would leave a strip of the image in no tile at all, which is the more damaging answer.
Using it
How do I split a picture into a grid?
Drop the picture onto the panel above, set the number of columns and rows, and the tiles appear immediately. Click one to save it on its own, or use the download button to take all of them as a single ZIP archive.
Is there a limit on image size or on how many tiles I can make?
There is no limit imposed by this tool. The practical ceiling is your own device's memory, since the picture and every tile are held in the browser. Grids up to 20 × 20 are offered, which is 400 tiles.
Should I set the split by cell count or by cell size?
By size when the tiles have to be a specific dimension — printing across sheets, cutting sprites, feeding a template. By count when the picture governs and the tile size is whatever falls out. The unit selector takes pixels, millimetres, centimetres or inches, so a print split can be specified in the unit the paper is in.
How do I keep track of which tile is which?
Leave the cell labels on and choose the scheme that matches where the tiles are going: A1/B2 for a person reassembling by hand, 1-1/2-2 for a script parsing them. The label is drawn into the overlay, so it is visible while you are checking the cuts.
Export and print
Can I split a picture across several printed sheets?
Yes, and this is the tidiest use for it. Set the cell size in millimetres to a little under your paper's printable area, split, and print the tiles one per sheet — you get a poster-sized image out of a desktop printer, with the margin keeping whole cells inside the printer's own unprintable border.
Do the tiles reassemble without a seam?
Yes, to the pixel — the cut is a division of the source, so nothing is resampled and adjacent edges match exactly. If a division does not come out whole, some tiles carry one extra pixel rather than every tile being scaled, which is what keeps the seam clean.
Choosing a grid
Why not use a command-line tool?
Use one, if you are splitting a hundred images on a schedule — that is what they are for. This wins for a single picture where you want to see the cuts before committing, and on a machine where installing anything is not an option.
Practical matters
Do my images get uploaded to a server?
No. Your browser decodes the picture and cuts it on a canvas in this page, and the ZIP is assembled here too. There is no upload step and no server side to this tool, which is why there is also no size limit and no queue.
Does it work on a phone?
Yes. The tool is a web page, so it works in any modern mobile browser, and the tiles download to your device the same way any other file does.
Can I use the tiles commercially?
The tool places no restriction on what you do with your own images. Rights in the picture you split are exactly what they were before you split it.
Is it free?
Yes, with no account, no watermark and no usage limit. The core tools on this site are free permanently; the paid product is a separate augmented-reality tracing app.
Is there a limit on how large an image I can split?
The practical limit is your device's memory, since the whole picture and every tile are held in the browser. A large photograph split into a few tiles is fine anywhere; a very large scan split into hundreds will run out of room on a phone long before it does on a desktop.
Open the tool Image splitter
One picture, however many pieces
The image splitter needs two numbers: set the columns and rows, then take the tiles singly or as a ZIP. Nothing uploaded, no signup, no watermark. For a nine-square feed the Instagram grid splitter uses the same cut, and the photo grid maker does the inverse — many pictures onto one sheet. The basic drawing grid overlays set out why the cell count matters in the first place.
