JPG · PNG · WEBP · HEIC — files never leave your browser

0 photos uploaded — ever.

All processing happens locally in your browser.

PNG-to-WebP conversion runs 100% client-side using the HTML5 Canvas API. Drop your file, then download it as WebP. The original never leaves your device.

Why convert PNG to WebP?

WebP keeps the lossless option of PNG (with the alpha channel intact) but typically delivers a 30% smaller file. For modern websites where every browser supports WebP, this is the easy compression win.

What changes during conversion

The browser decodes the source file into a pixel buffer, then re-encodes that buffer with the WebP encoder. Pixel dimensions are preserved unless you explicitly resize. Color profile (sRGB) is preserved. EXIF orientation is honoured before encoding so the output is upright. Personal metadata (GPS, camera serial, owner) is stripped by default.

Quality & file size

WebP usually delivers the same visual quality as JPG at 25–35% smaller file size, and it supports both lossy compression and an alpha channel. It is supported by every modern browser, but a few legacy desktop apps and some government upload portals still reject it — when in doubt, JPG is the safer fallback.

How to convert

Drop your PNG file into the editor above. Multiple files at once? Use our batch resizer.
Optionally crop or resize. Leave the size mode on "Free" to keep the original dimensions.
Click the Download WebP button.

Privacy

Every step happens inside the browser tab you have open. Your image is decoded, cropped and re-encoded by the same JavaScript engine that runs this page — there is no upload, no temporary file on a server, and no "processed copy" cached by us afterwards. When you close the tab, the blob is gone. We document the full pipeline on our Methodology and How it works pages.

FAQ

Is PNG to WebP conversion safe?

Yes. The image stays in your browser; nothing is uploaded.

Will I lose quality?

WebP is typically 25–35% smaller than JPG at similar visual quality. You can pick the encoder quality.

Does conversion lose quality?

Lossless → lossless conversions (PNG ↔ WebP-lossless) preserve every pixel. Lossless → lossy (PNG → JPG) introduces a one-time encoding step; for typical photographs the visual difference is invisible above quality 0.85. Lossy → lossy is technically a re-encode but, again, invisible at high quality.

Are batch conversions supported?

Yes. Use the batch resizer to drop up to 50 files at once and download a single ZIP.

Which browsers are supported?

Chrome, Edge, Firefox, Safari and Brave on desktop, plus Chrome and Safari on iOS / Android. The editor relies on the standard HTML5 Canvas API and an on-demand WebAssembly module for HEIC decoding — both are available in every browser version released since 2020.

What happens to my image after I close the tab?

It is freed from your browser's memory like any other image you opened. We never received it, so we have nothing to delete on our side. See Trust & Safety for the full policy.
