How to Convert WebP to JPG or PNG

Search for anything about WebP for long enough and you'll eventually run into the opposite question: not how to convert to it, but how to turn one back into a JPG or PNG. That's not really a contradiction. WebP is smaller and usually higher quality, but plenty of the places you might need to send an image (an old form, a specific piece of software, a print shop) never got the memo.

Why you'd need to convert WebP backward

A few genuinely common situations:

  • Older software chokes on it. Plenty of versions of Microsoft Word, some photo viewers, and older image editors either don't open WebP at all or handle it awkwardly.
  • A platform or form only accepts JPG/PNG. Some marketplaces, print services, government forms, and older CMS upload fields explicitly reject WebP; you'll get a rejected upload or a generic error with no explanation.
  • Someone else needs to open the file and isn't particularly tech-savvy. If you're sending a photo to someone whose phone or app doesn't render WebP cleanly, JPG is the safer bet.
  • You're pasting into a document or slide deck that expects standard image formats and shows WebP as a broken icon.
  • A design or print workflow expects PNG specifically, whether for transparency, a particular color pipeline, or simply because that's what the tool requires.

None of these mean WebP was the wrong choice originally. They just mean the format needs to match whatever is on the receiving end.

JPG or PNG: which one when you convert back

Quick rule of thumb:

  • JPG for photos and anything without transparency. Smaller files, universally supported.
  • PNG if the original WebP has a transparent background, or if it's a screenshot, logo, or graphic with flat colors and sharp text — JPG's compression tends to blur that kind of content.

WebP supports transparency (like PNG), so if you convert a transparent WebP to JPG, you'll lose the transparency — it gets filled in with a solid background instead. If that matters, convert to PNG.

Will you lose quality doing this?

If the WebP was saved with lossy compression (the default, and almost always the case for photos), it already went through one round of quality loss before you even start converting it. Turning it into JPG adds a second lossy pass, so a small amount of additional degradation is unavoidable in the strictest sense. In practice, if you keep the JPG quality setting reasonably high (80+), the difference isn't something you'll notice at normal viewing size. It only becomes visible if you convert back and forth repeatedly, or set the quality very low.

If the WebP was saved lossless (less common, but it happens with graphics and screenshots), converting to PNG keeps you lossless the whole way through, with no quality loss at all.

How to actually do it

img-compress's WebP to JPG converter handles this entirely in your browser: pick JPG if you don't need transparency, or switch to the WebP to PNG converter if you do, then download the result with nothing having touched a server in between. A batch of files works exactly like a single one; the whole set processes together and comes back as one ZIP.
