About this tool
Lossless, and honest about the size
WebP, AVIF, HEIC or JPG in — lossless PNG out, with transparency intact. Tick OxiPNG if you want it recompressed properly.
PNG stores every pixel exactly, which is why it is what design software expects and what a cut-out should be saved as. It is also why converting a photograph to PNG makes the file much larger, and why re-saving a PNG that was already optimised makes it bigger rather than smaller. Both of those are stated plainly here rather than hidden — and the OxiPNG option exists for when you actually want the file squeezed.

Every pixel preserved
No quality dial, because nothing is discarded. Convert, crop or rotate and the pixels that survive are bit-for-bit what you started with.
Transparency, universally understood
A real alpha channel that every editor, browser and operating system reads. It is the safest home for a cut-out or a logo.
OxiPNG when size matters
A plain re-save is lossless but unoptimised, so an already-optimised PNG comes out larger. Tick OxiPNG to recompress properly — and the tool tells you when the file grew instead of pretending otherwise.
Step by step
How to convert an image to PNG
Add your image
Drop a WebP, AVIF, HEIC or JPG — or several at once to convert a batch.
Keep it lossless
PNG is lossless, so there is no quality to set. Tick OxiPNG if you want the file recompressed smaller at the same pixels.
Download
Save the .png file straight to your device. Every step is in the history, so you can undo before you save.

Questions
Questions about this tool
Everything here runs in your browser, so the answer to “where does my file go?” is always: nowhere. More in the general FAQ.
How do I convert a WebP to PNG?
Drop the WebP and this page opens with PNG selected, then press Download. Transparency is carried across. This is the usual fix when software refuses to open a WebP you saved from the web.
Why is my PNG bigger than the original?
Because PNG is lossless. Converting a JPEG, WebP or AVIF photograph to PNG throws away all the compression that made it small, and re-saving an already-optimised PNG through a plain encoder loses its optimisation. The tool reports growth explicitly, in amber, rather than implying a saving. Tick OxiPNG, or convert to WebP instead, if size is the goal.
Does converting to PNG improve quality?
No. PNG preserves exactly what it is given; it cannot restore detail an earlier lossy save discarded. Converting a JPEG to PNG gives you a larger file of the same quality — worth it only if the image is about to be edited repeatedly.
When should I use PNG instead of WebP or AVIF?
When you need guaranteed lossless quality, when transparency has to be understood by older software, or when the image is line art, a screenshot or a logo — flat-colour graphics where PNG is genuinely competitive on size.
Does PNG keep transparency from a HEIC or WebP?
Yes, wherever the source has an alpha channel. HEIC photos from a phone are normally fully opaque, so the PNG will be too.
