WebP is what you get when you save an image from most modern websites, and it is frequently the wrong format to have. Microsoft Office refuses it, plenty of desktop photo viewers do not recognise it, print shops reject it and older phones cannot display it. This tool decodes WebP in the browser and re-encodes it as JPG or PNG, both of which are opened by essentially everything.
Which target you pick matters. JPG is right for photographs and for anything that has to go into a document or be emailed. PNG is right for logos, illustrations, screenshots and any image with transparency, because a lossless WebP converted to JPEG would both lose its alpha channel and pick up compression artefacts on its sharp edges.
The decode and re-encode both happen in your browser using its native WebP support. No image is uploaded, and nothing is cached on a remote server.
| Your image is | Convert to | Why |
|---|---|---|
| A photograph | JPG | Small file, universal support, no visible loss at High |
| A logo or icon | PNG | Keeps transparency and perfectly sharp edges |
| A screenshot | PNG | JPEG softens interface text and adds halos |
| A chart or diagram | PNG | Thin lines and flat colour survive intact |
| Headed for print | JPG or PNG | Print workflows still rarely accept WebP |
WebP can hold an animation, much like a GIF. The browser’s image decoder used here reads only the first frame, so an animated WebP converts to a single still picture rather than to an animated output. There is no way to preserve motion when the destination is JPG or PNG, neither of which supports frames.
WebP is a web-first format. Browsers all support it, but Office applications, many desktop viewers, print workflows and older devices do not. Converting to JPG or PNG removes the compatibility problem entirely.
JPG for photographs and anything destined for a document or email. PNG for logos, icons, screenshots, charts and any image whose transparency you need to keep.
Only if you convert to PNG. JPEG has no alpha channel, so a transparent WebP converted to JPG is composited onto white.
Usually. WebP compresses more efficiently than both JPEG and PNG, so expect the JPG to be somewhat larger and the PNG to be considerably larger. That is the cost of universal compatibility.
Only the first frame is converted. JPG and PNG cannot store animation, so the output is a single still image.
No. Your browser already knows how to decode WebP; this page uses that built-in support and re-encodes locally. Nothing is transmitted.
