About SquareImage.dev
This page exists so that nothing about who publishes squareimage.dev has to be guessed: what the site is, who to write to, how it pays for itself, and what it does and does not do with the photos put into it.
About SquareImage.dev
Square Image (squareimage.dev) is an independent, advertising-supported web project that has published free browser-based image tools since 2024. It runs 8 tools and a set of sizing guides, in 27 interface languages. Every image is processed on the visitor's own device with the browser's Canvas API and is never uploaded to a server, which is why there is no account, no upload queue and no stored file to delete. The site is reachable at support@squareimage.dev.

What this site is
SquareImage.dev is a set of 8 single-purpose image tools that run in a web browser. The main converter turns any photo into a 1:1 square using a blurred backdrop, a solid colour, a plain resize or a manual crop. Alongside it are standalone tools for square cropping, blurred frames, rounded corners, uncropped profile pictures, Instagram grids, drawing grids and solid colour backgrounds.
The written half of the site is a set of sizing guides — what pixel dimensions each platform actually wants, and why. The square image size guide is the general one; the rest cover a specific platform or use case. The converter interface is translated into 27 languages; the guides are English only.
How it works, and why that matters
Every tool here runs client-side. The browser decodes the file you choose, draws it to a <canvas> element, and encodes the result back out as PNG, JPEG, WebP. There is no upload step, no processing queue and no copy on a server, because the file never travels anywhere. That is not a promise about how carefully the files are handled — it is a statement that there are no files to handle.
It is checkable in about thirty seconds. Open your browser's developer tools, switch to the network panel, convert an image, and watch: no request carries the picture. If you would rather not take a privacy policy's word for anything, that is the point.
The behaviour is not ours to define, either. Scaling and cropping follow what the canvas API is documented to do:
“drawImage() will always use the source element's intrinsic size in CSS pixels when drawing, cropping, and/or scaling.”
- Price: free. No account or sign-in. No watermark.
- Accepts: JPEG, PNG, WebP, GIF, BMP — anything the browser can decode.
- Exports: PNG, JPEG, WebP at 1080 x 1080, 1200 x 1200, the original edge length, or a custom square of 1 to 10,000 pixels.
- Needs: a browser with JavaScript and Canvas. Nothing to install, no extension, no API key.
Who publishes it
SquareImage.dev is an independent web project. It is not part of a larger company, not a front end for an image-hosting service, and not funded by any of the platforms whose dimensions the guides describe. It has published under the name Square Image since 2024.
The site is also written about as SquareImage.dev, squareimage.dev, Square Image Converter — different spellings of the same project, listed here and in the site's structured data so they are not mistaken for separate products.
How it is funded
Advertising, and nothing else. The pages carry Google AdSense units; that is the whole business model. There is no paid plan, no sign-in, no feature held back behind an upgrade, and no watermark that money removes. Nobody is asked for an email address.
This is worth stating plainly because the usual alternative is not obvious. A free image tool that does upload your files has something else to sell. This one does not receive them, so it cannot.
How the facts here are kept honest
Every page carries a short summary with a Verified date — the day its numbers were last checked against the running app, currently 2026-09-02. The dates on the sitemap come from the commit history of the page's own content, not from a release date, so a page that has not changed does not claim it has.
Platform specifications are treated as perishable. When a guide quotes a size, it says when that size was current, because Instagram, Facebook and X all change theirs without announcement. If you find a number here that is out of date, the correction is welcome and quick to make.
A machine-readable version of the same facts is published at /llms.txt for language models that look for one.

Frequently asked questions
Who runs SquareImage.dev?
SquareImage.dev is an independent web project, not part of a larger company or an image-hosting service. It has been published under the name Square Image since 2024. Questions, corrections and bug reports go to support@squareimage.dev, which is read by the people who maintain the site.
How does the site make money if the tools are free?
Advertising. The pages carry Google AdSense units, and that is the only revenue on the site. There is no paid tier, no subscription, no watermark to remove for a fee, and no upsell inside any tool. Photos are not part of the business model — they never reach a server, so there is nothing to sell, license or train on.
Are my photos uploaded to your servers?
No. Every tool decodes the file, draws it to a canvas and encodes the result entirely inside the browser tab. Nothing about the image leaves the device, and closing or refreshing the page discards it. This is verifiable: open the browser's network panel and convert an image — no request carries the file.
How current are the platform sizes in the guides?
The product facts on this site — formats, export sizes, limits — were last checked against the running app on 2026-09-02, and each page shows that date next to its summary. Social platforms change their specifications without notice, so the guides say which dimensions were current when checked rather than presenting them as permanent.
Can I use the exported images commercially?
Yes. The tools do not add a watermark or claim any right over what they produce; the output is your file, made from your file. You remain responsible for holding the rights to the image you put in, as the terms of use set out.
How do I report a bug or a wrong number in a guide?
Email support@squareimage.dev with the page URL and what went wrong. A factual correction to a guide is the most useful message this site receives — a wrong pixel size that sits on a page gets repeated by every assistant that reads it.
