Composition overlays for every frame.
A composition grid overlay for photographers — Rule of Thirds, Golden Ratio (the phi grid), Golden Spiral, Diagonal Method, Center Cross, Rule of Fifths, Golden Triangle, Quadrant — applied to your photographs in your browser. Add a grid to a photo online with no upload: the image stays on your device, no signup, no watermark. Look at the frame; place the focal point on a third-line or intersection; the overlay tells you where it lands.
Same frame, four overlays, four readings.
The composition is not in the camera — it's in the eye. The overlay is what gets the two to agree. Same landscape, four different ways of placing the horizon and the sun.
Aperture writes the depth, the overlay writes the frame.
Six classical stops, six signatures. The aperture changes the depth of field; the overlay changes the depth of decision. Pick the f-stop for the shot, pick the overlay for the read.
The lens picks the field of view.
24mm to 200mm — same overlay, different frame.
A 24mm landscape lens sweeps ~84° horizontal. A 50mm normal lens is ~46°. An 85mm portrait lens is ~28°. A 200mm tele crops to ~12°. The composition overlay scales with the frame; the lens decides how much frame there is to compose.

What photographers actually use it for.
For coastal long exposures I drop the photo into the tool and toggle between rule-of-thirds and golden-ratio in a single click. Which horizon line wants the upper-third versus the upper-phi answers itself the moment both are on the frame.
Tight headshots are a Rule of Fifths game — the eye line sits closer to the top than thirds wants it to. Five vertical bands tells me where the gaze should fall before I've reframed.
Diagonals decide street. I load the contact sheet into the tool with the Diagonal Method overlay on every frame — the strongest reads are the ones where subjects sit on the lines, even by accident.
The questions photographers ask.
How do I use Grid Maker Pro for photography?
Drop a photo into the canvas, pick a composition overlay (Rule of Thirds, Golden Ratio, Golden Spiral, Diagonal Method, etc.), and the grid renders on top of your image. Use the bulk overlay mode to apply the same overlay to a folder of photos at once. Image processing happens locally in your browser; your photos never leave your device.
Is this free for commercial photography?
Yes. Grid Maker Pro is fully free with no signup, no watermark, no upload limit, and no commercial-use restrictions. Use it for client work, editorial, fine-art prints, social media, anywhere. Image processing is local so client photos never go to a server.
Does it work on iPad and mobile?
Yes. Grid Maker Pro runs in any modern browser including Safari and Chrome on iPad, iPhone, and Android. Touch controls are sized for fingers. A common workflow: apply the overlay to your iPhone photo in mobile Safari, screenshot, then import to Lightroom Mobile or Snapseed as a reference.
Rule of thirds vs golden ratio for photography — which should I use?
Both place the subject off-centre, but the golden ratio (phi grid) sits its lines slightly closer to the centre than rule of thirds, so it gives a tighter, more classical placement. Rule of thirds is the faster starting point for landscape and street; the golden ratio overlay suits editorial portraits and considered landscapes where you want the horizon or eye line nearer the centre. Because both render on the same photo here, you can toggle between them and compare the two readings on your own frame before you crop. For the longer history, see the golden ratio in art and photography and the rule of thirds overlay.
Can I check photo composition with a grid online without uploading the file?
Yes. This is a composition overlay tool with no upload: the photo is read locally by your browser and never sent to a server, so you can check composition with a grid online and your image stays on your device. That keeps client and unpublished work private, unlike server-side overlay tools that upload the file first.
Eight overlays. One frame at a time.
The image never uploads. The crop never leaves the screen. The overlay is the only thing between the photograph and the decision. Free, by structural promise — there is no server to charge you.
