Real grid overlay transparency
The grid overlay exports with a genuine alpha channel — not white, not checkerboard. What you layer is lines and nothing else.
Grid Overlay
Create a transparent grid overlay as a true alpha-channel PNG — set the canvas, cell size and line style, then download a grid you can stack over any background.

Transparent mode exports PNG only, so the alpha channel is preserved.

What is a grid overlay?
A grid overlay is a grid drawn on transparency, meant to be layered on top of something else: an editing frame, a design mockup, a photo, a map. Because the background is genuinely transparent — a real alpha channel, not a white or checkerboard imitation — the grid overlay drops into Photoshop, Figma, Premiere, slides or web pages and only the lines show.
This grid overlay generator starts you on a 1920 × 1080 transparent canvas with 100-pixel cells, which matches full-HD work out of the box. Need something else? Resize the canvas up to 4096 pixels, choose exact pixel spacing for the cells, and pick the line color and weight that suit the material underneath. An optional image upload lets you preview how the grid overlay sits on real content before you download.
The export is a PNG precisely because PNG preserves transparency; JPG cannot. The downloaded file contains only your lines on alpha — no background, no watermark, no compression artifacts around the edges. Import it, screen it, or composite it: a clean grid overlay that fits any pipeline.
What a transparent grid overlay is for
Whenever you need to judge or communicate position on top of existing visuals, a grid overlay is the fastest reference layer. Editors align motion and titles against a grid; designers check spacing and the rule of thirds; streamers build overlay layouts; teachers demonstrate proportion on top of shared images. The overlay does the measuring, the content stays untouched.
A transparent PNG is the universal currency for this. Every serious image and editing tool accepts it, keeps the transparency, and lets you scale or tint the grid overlay without quality loss. That is why this tool outputs PNG only in transparent mode — it is the one format that guarantees your grid arrives see-through.

Choosing grid overlay dimensions
Match the canvas to the material you will overlay. 1920 × 1080 fits full-HD work and most screens; 3840 × 2160 covers 4K; square sizes suit social formats. If the target is a photo, set the canvas to that photo's dimensions and the grid overlay will register pixel-for-pixel once layered.
Cell size sets the rhythm of the grid. 100-pixel cells read clearly on motion work; 50-pixel cells give finer guidance for detailed work; larger 200-pixel cells stay subtle in the background. Combine with a light color and lowered opacity when the grid overlay must guide without distracting viewers.
Working the overlay into your project
In editors like Photoshop or GIMP, place the grid overlay above your content and set the blend mode to Normal or Screen; scale once to fit if you built a different canvas size. In editing tools, import the PNG as a top layer and it will hold over every frame. In slide and web work, use it as a background-image behind or above content zones.
Because the lines are crisp 1-to-10-pixel strokes centered on true geometry, the grid overlay stays sharp when scaled down and only softens predictably when blown far up. For extra precision, generate several overlays — a fine one and a bold one — and toggle between them as the job demands.
How to make a grid overlay in four steps
Set the canvas
Start from 1920 × 1080 or type your exact target size — the grid overlay is generated at your dimensions, up to 4096 pixels.
Choose cell size and lines
Pick pixel spacing for the grid overlay cells, then line color, width and opacity. Gray defaults stay neutral over any background.
Preview on an image (optional)
Drop any photo onto the grid overlay tool to preview the lines over real content before committing to a download.
Download the transparent PNG
Export a true alpha-channel PNG with only your lines — ready to layer in any design, motion or presentation tool.
A grid overlay built to layer
Pixel-exact cells
Cells are defined in absolute pixels, so a 100 px grid overlay reads as 100 px over film frames, mockups and photos alike.
Big enough for 4K
Canvas sizes reach 4096 pixels on each side, covering full-HD, 4K and print-scale layouts in one file.
Instant and local
The grid overlay renders in your browser in real time; no account, no queue, no upload — just download and drop it in.
Grid overlay FAQ
Why is the export PNG only?
Because only PNG reliably stores transparency. A JPG grid overlay would arrive on a white background, defeating the purpose — so the grid overlay exports as PNG, never JPG.
What canvas size should my grid overlay use?
Match your target material: 1920 × 1080 for HD frames, 3840 × 2160 for 4K, or your photo's exact dimensions so the grid overlay registers pixel-for-pixel.
Can I see the grid over my own image first?
Yes — the optional upload previews your image under the grid overlay, so you can tune color and opacity against real content before downloading.
Will the lines stay sharp when I scale the overlay?
Downscaling stays crisp. Enlarging a raster grid overlay beyond its canvas will soften it — regenerate at the larger size instead; it takes seconds.
Is the grid overlay free to use commercially?
Yes. The grid overlay you generate is yours — use it in client work, films, games or products. No watermark, no attribution, no fee.
