Convert WebP to PNG in your browser
Drop a WebP and Tinier converts it to PNG locally on your device. PNG is lossless and opens in every image editor, email client and app — handy when a tool refuses WebP. Transparency is preserved. Nothing uploads; disconnect your internet after the page loads and it still works. Up to 50 MB per file, 1 to 20 at a time.
Why convert WebP to PNG?
WebP is great for the web, but some older editors, email clients and desktop apps still cannot open it. Converting to PNG gives you a file that opens everywhere and is lossless — a clean, editable copy. If a program rejected your WebP, a PNG is the safe universal answer, and it keeps any transparency the WebP had.
Why is the PNG larger than the WebP?
PNG is lossless: it stores every pixel exactly, with no perceptual compression. WebP squeezes the file much smaller by discarding imperceptible detail. So a WebP-to-PNG conversion almost always produces a bigger file — that is expected and correct. You are trading size for a lossless, universally-compatible copy, not shrinking the image.
Why convert in your browser instead of a server?
Tinier decodes WebP and re-encodes PNG locally with WebAssembly, so the WebP is never uploaded. It is faster than a server tool on files under 10 MB because there is no round-trip, and it is private by construction. No account, no rate limit, no size paywall.
Frequently asked questions about WebP to PNG
Is my WebP uploaded to a server?
No. The conversion runs entirely in your browser with WebAssembly. Your WebP never leaves your device — you can turn off your internet after the page loads and it still works.
Is transparency kept?
Yes. PNG supports alpha transparency just like WebP, so transparent areas are preserved exactly.
Why did the file get bigger?
PNG is lossless, so it stores every pixel exactly and is usually larger than the WebP it came from. That is normal — you convert to PNG for compatibility and a lossless, editable copy, not for a smaller file.
Can I convert several WebP files at once?
Yes. Drop up to 20 WebP files and download them individually or as a ZIP. Everything runs on your device.
