About these tools

One-click presets for visa, marketplace and social media upload requirements. They share a small number of engines configured differently on each page — a target file size, and where a form demands it, exact pixel dimensions. The result is tuned to the specification you actually need to meet, rather than a generic "make it smaller" pass.

Processing happens on your device. Your files are never uploaded to a server, which is why there are no usage limits and no account to create.

Frequently asked questions

What platform specs are on this site?

There are 30 in this category: US Visa Photo — 2×2 Inches, Under 240 KB, UK Passport Photo — Digital Upload Size, Schengen Visa Photo — 35 × 45 mm, Canada Visa & Citizenship Photo Size, Australia Visa Photo — 35 × 45 mm, New Zealand Visa Photo Size, and 24 more. One-click presets for visa, marketplace and social media upload requirements.

Are the platform specs free to use?

Yes. No account, no trial, no watermark and no cap on how many files you process. Every setting is available to everyone.

Do my files get uploaded?

No. These tools run entirely in your browser, so the file never leaves your device. You can confirm it in your browser’s Network tab, or by disconnecting from the internet once the page has loaded — the tools keep working.

Do I need to install anything?

No. There is nothing to download and no extension to install. Open the tool you need and use it.

Why does each platform need a different size?

Because each one crops and re-encodes uploads to its own specification. Supplying the exact dimensions a platform expects avoids its automatic crop choosing the wrong part of your image.
