Sample WebP Files — Download Test WebP Images (50 KB to 1 MB)
WebP — Google's web image format · .webp · MIME type image/webp
Download a sample WebP file at 50 KB, 200 KB, 500 KB or 1 MB, with resolutions from 640×480 to 3840×2160. Use them to confirm that a browser, CMS, email client or image library actually decodes WebP — older tooling still fails on it — and to compare sizes against the equivalent JPG on our JPG page.
WebP, released by Google in 2010, offers both lossy and lossless modes, alpha transparency and animation in one container, at roughly 25–35% smaller sizes than JPEG at equal quality. Since Safari 14 (2020) it plays in every major browser, and most image CDNs now serve it by default.

Frequently asked questions
Is WebP better than JPG?
For the web, usually: at the same visual quality a WebP is typically a quarter to a third smaller than a JPG, and it also supports transparency. JPG still wins for compatibility with older software, cameras and print workflows, which is why most sites keep a JPG fallback.
How do I open a WebP file on Windows or macOS?
Windows 10/11 Photos and macOS Preview (Big Sur or later) open WebP natively, as does every modern browser. If a tool refuses it, convert to PNG or JPG in your browser with our free Image Converter — no upload required.
Are these WebP files safe to download?
Yes. Every file is generated by our own open script from scratch — nothing is scraped or user-uploaded — and contains no scripts, macros or executables. The SHA-256 of each file is published on this page so you can verify what you received.
Can I use the sample WebP files commercially?
Yes. They are free for any purpose, including commercial products, test suites, demos and redistribution, with no attribution required. There is nothing to license and no one to ask.
Can I hotlink these files or use them in CI?
Yes. Every link is a stable direct URL over HTTPS with Access-Control-Allow-Origin: * and long cache headers, so curl, wget, fetch() and test runners can pull them directly. A JSON index of every file is linked from each page (see the command-line section).
