Free · No signup · Files stay local
Drop a reference photo, set the rows and columns, crop if you need to, and download a PNG or JPG with the grid already drawn. Diagonals, composition guides, and high-res PNG are free. The work stays in this browser. Nothing uploads and you do not create an account.
Drag & drop your reference image here
Supports JPG, PNG, GIF, WEBP
PNG for print. JPG is smaller. High-res PNG is 4× the pixels — one larger file, not four copies.
Features
The first viewport is the working overlay: drop a photo, set the grid, and download PNG or JPG. SEO copy sits below the card. There is no compressor and no signup wall.
Change rows, columns, color, width, or opacity and the preview updates in this tab. Crop and rotate the photo, then add diagonals or a thirds / golden-ratio overlay. The identity line shows the filename, pixel size, and grid so you know which file you are about to save.
The image is opened with FileReader and painted on a canvas in this browser. We do not upload it, we do not store it after you leave, and a weak connection does not block the download. That is the privacy model on this page, not a later setting.
Upload image, Download PNG, Download JPG, and Download 4× PNG sit under the preview. 4× PNG is free here. View enlarges the same canvas on this page. We do not send you to a CDN or a blank tab to see the result.
Rows and columns go from 2 to 50. Diagonal triangulation, rule of thirds, golden ratio, crop and rotate, and 4× PNG are on this card with no trial. Other sites put those behind a subscription. Very large photos are capped only so the tab stays stable, and the status line says so.
What it is
This grid maker is a browser page that overlays even squares on one reference image so you can copy proportions onto paper square by square. You drop a JPG, PNG, GIF, or WEBP, choose how many rows and columns to use, and the canvas in this tab redraws immediately. You can crop and rotate, switch on A1 labels, draw diagonal triangulation, or drop a rule-of-thirds or golden-ratio overlay. Other sites sell those as a subscription. They are free on this card.
The photo is read locally and never posted to our server. Download PNG when you want sharp edges for a print; download JPG when you want a smaller file. This page is not a mural calculator, a paint-by-number generator, an Instagram feed splitter, or a crochet chart. Those jobs need other tools. Here the job is one overlay you can see and save before you pick up a pencil.
How to use
Step 1
Drop a JPG, PNG, GIF, or WEBP on the card, or click to pick one file. You can also leave the blank 800×600 canvas if you only need an empty grid. PDF and video are not accepted here.
Step 2
The overlay starts at 8×8. Drag Rows to add or remove horizontal lines, and Columns for vertical lines — each slider is independent, and the photo updates as you drag. Tune color and opacity so the lines stay visible. Labels, diagonals, and composition overlays sit under More options. Crop first if the photo includes extra background.
Step 3
Confirm the filename and pixel size in the result heading. Download PNG for a print-ready reference, JPG for a smaller file, or Download 4× PNG when you need a larger print. Print that image and rule the same number of squares on your paper.
Limits
This homepage is the grid maker: overlay even squares on one photo and download. Searches for grid drawing, grid drawing tool, and grid for drawing belong on the grid drawing tool page. Add grid to photo lands on add grid to photo. A grid overlay for drawing lives at grid overlay. The paper-copy tutorial is the grid method. Diagonals, thirds, golden ratio, crop, and 4× PNG stay free here. This URL still does not split an Instagram feed or export a crochet chart.
Why choose
What you gain by using this tool, written from the product.
Several grid sites still talk about upload even when the work is local. This page is explicit: FileReader plus canvas, no form post, no account. If you are drawing a client portrait, that is the reason to stay here instead of a tool that stores files.
You see the overlay before you save. Identity sits above the buttons so you are not downloading an anonymous file. View enlarges the same canvas on this page. That is faster than exporting blindly and opening the file in another app.
Other grid sites lock diagonals, rule of thirds, golden ratio, and 4× prints behind a subscription. This homepage gives those controls on the same card, with no account and no trial. The grid you see is the grid you can save.
The URL is a drawing grid overlay, not a bundle of mural math, coloring pages, and feed splitters. Sibling pages can exist later if the job actually changes. Synonym copies of this same overlay will not be invented for extra keywords.

Practical tips, limits and common fixes.
Use cases
When and how to use it, written as recipe cards.
You have a head-and-shoulders photo and want to copy proportions onto sketch paper without guessing the eye line.
Input: One JPG or WEBP portrait already on the phone or laptop, any common camera size.
Setting: 10 rows by 10 columns, labels on, dark line at about 35 percent opacity.
Output: A PNG of the same photo with a 10×10 overlay you can print or keep on a second screen.
Caveat: This does not correct lens distortion. Use Crop & rotate on this card if you only want the head.
A teacher needs the same gridded reference for a table of students, without making an account for a class set.
Input: One still-life PNG or JPG of the object on the demo table.
Setting: 8×8 grid, labels on so you can say “look at cell C4”, medium line width.
Output: One PNG you print in bulk. Every student works from the same squares.
Caveat: We do not generate a worksheet pack or seating chart. You still photocopy or share the PNG yourself.
You already have a small sketch and will chalk a matching grid on a wall. You need the overlay on the sketch, not a paint estimator.
Input: A photo or scan of the sketch as JPG or PNG.
Setting: Coarse grid such as 6×6 or 8×8 so chalk lines on the wall stay practical.
Output: A PNG of the sketch with the same number of squares you will rule on the wall.
Caveat: This page does not calculate gallons of paint or chalk-line positions in feet. Count squares by hand.
FAQ
A grid maker overlays even squares on a reference photo so you can copy proportions square by square. This page is an online drawing grid: it draws the overlay in your browser, then lets you download PNG or JPG. Nothing is uploaded and you do not create an account.
Yes. The homepage grid maker is free. You can drop a photo, crop it, set rows and columns, switch on diagonals or composition overlays, and download PNG, JPG, or 4× PNG without paying, signing in, or starting a trial. Other sites charge for those extras.
No. There is no login, no email wall, and no Pro trial on this page. Diagonals, composition overlays, crop, and 4× PNG work without an account. The image stays in this tab until you close it.
No. The photo is read with FileReader and drawn on a canvas in this tab. We do not post it to a server, and we do not store it after you leave. That is why a flaky connection does not stop a download.
Use JPG, PNG, GIF, or WEBP. One image at a time. If the file is not an image, the card says so instead of drawing a blank. PDF, PSD, and video are not accepted on this homepage.
Yes. Download PNG is the print-ready file. Download JPG is smaller. High-resolution PNG writes a 4× file on this card with no trial. Other sites put that behind a signup. This page does not export PDF, ZIP, or layered PSD.
Start at 8×8, the same default as a typical drawing grid. Drag Rows to change only the horizontal lines, and Columns to change only the vertical lines. The overlay on the photo redraws as you drag. Square cells is off unless you turn it on under More options.
Yes. Drop a JPG, PNG, GIF, or WEBP on the card and the overlay is drawn on that photo in this tab. Set rows and columns, then download PNG or JPG. That is a drawing grid overlay: the picture is never posted to a server.
Both names point at this card. A grid overlay is the lines on top of your reference. A grid generator here means the same overlay with a row and column count you pick, including a blank 800×600 canvas if you have no photo yet. It is not a CSS layout tool or a 3D table generator.
Yes. That is the job on this homepage: a drawing grid on one reference so you can copy proportions onto paper. There is no app to install. Open the page, drop the photo, set the grid, and download. Instagram splitters and paint-by-number generators are different products and are not on this URL.
Yes. Rows and Columns are independent from 2 to 50. You can run 8 rows by 18 columns on a wide photo, or any other pair in that range. Square cells is optional and off by default. Counts above 50 are not offered, so the tab stays usable.
No. This grid maker runs in a normal desktop or phone browser. There is no iPhone app, Chrome extension, or extra install. If a search result is an app store listing, that is not this page.
Yes. The same card works in a mobile browser. Drop or pick a photo, drag the row and column sliders, then download. Very large photos are capped so the tab stays stable; the status line says if the export was resized.
No. Artists have used a matching grid on a reference and on paper for centuries to judge proportion. This page only draws the overlay. You still make every mark on your canvas. It is a measuring aid, not a tracer that paints for you.
Download PNG for the cleanest print. Print that file and rule the same number of squares on your paper. This homepage does not build a multi-page PDF or letter-size print sheet. If you need blank graph paper, that is a different job.
No. This page overlays a drawing grid on one reference photo. It does not split a feed into nine posts, and it does not export a crochet or knitting chart. Use a splitter or a pattern tool for those jobs.
It is optional and off by default. Turn it on under More options if you want each cell close to a square: dragging Rows then also updates Columns to match the photo’s shape. Leave it off to set any row count and any column count on their own, including 8 rows by 18 columns on a wide photo.
No. The photo replaces the blank canvas, but Rows and Columns stay where you set them. Drag either slider and only that axis changes on the overlay. Start over clears the photo and puts the grid back to 8×8.
It turns the reference into grayscale so you can judge light and shadow without color. The grid, labels, and downloads stay the same. It is off by default. Line width, labels, diagonals, and composition overlays sit under More options.
An online grid maker is a browser page that overlays rows and columns on a photo so you can copy proportions onto paper. This homepage is that tool: drop a JPG or PNG, set the count, and download. You do not install an app, and the file is not posted to a server.
Yes. The homepage grid maker is for drawing from a reference: overlay even squares, then download PNG or JPG and match the count on paper. If you specifically typed grid drawing tool or grid for drawing, the same overlay also lives on the drawing-grid page with that framing.
Same card, different search phrase. This URL answers grid maker and online grid maker. The drawing-grid page answers grid drawing, grid drawing tool, and grid for drawing. Instagram splitters, crochet charts, and blank A4 graph packs are on neither page.
Drop a photo and download the overlay in the first viewport. This button only scrolls there.
