Convert PNG to WebP
Convert PNG to WebP in your browser. Photographs typically drop 70-90% in size, transparency is kept, and nothing is uploaded.

PNG to WebP is the conversion with the most to gain, because PNG is lossless and stores every pixel exactly as it was. That is the right choice for a screenshot of text or a logo with hard edges. For a photograph it is enormously wasteful: the same image can easily be eight or ten times larger as a PNG than it needs to be.
Where the saving lands depends entirely on what the image contains. A photograph or any picture with soft gradients usually drops by 70-90%. A flat logo with four colours may only drop by half, because PNG already compresses large blocks of identical colour very efficiently. Both results are shown per file so you can see which you got.
Transparency survives intact. WebP has a full alpha channel, so cut-out product shots, logos and icons come through with soft edges preserved rather than acquiring a white box. This is the main reason to convert a transparent PNG to WebP rather than to JPEG.
One case where you should not convert: if the PNG is a screenshot containing small text, and the text must stay razor sharp, lossy WebP will soften it slightly. Either push the quality up to 95 or keep the PNG for that particular image.

Frequently asked questions
How much smaller will my PNG get?
For photographs, typically 70-90% smaller. For flat graphics and logos, often 30-60%. PNG is already efficient at compressing large areas of identical colour, so simple images have less redundancy left for WebP to remove.
Does WebP keep PNG transparency?
Yes, completely. WebP supports a full 8-bit alpha channel, so semi-transparent edges and drop shadows are preserved exactly as they were. Converting to JPEG instead is what destroys transparency, filling it with white.
Is WebP safe to use on a live website?
Yes. Chrome, Firefox, Safari and Edge have all supported WebP for years, so the browsers your visitors use will display it. The gap is in older desktop software, which is a reason to keep a PNG copy of source files rather than a reason to avoid WebP on the web.
Can I convert a folder of PNGs at once?
Yes. Drop the whole folder onto the box above. Files are processed in parallel across your CPU cores and can be downloaded together as a ZIP when the queue finishes.
