À propos de cet outil

This is the conversion people need after saving an image from a website. Sites increasingly serve WebP because it is smaller and faster, so "save image as" now hands you a .webp file - and then Windows Photo Viewer will not open it, the print shop rejects it, the job portal refuses the upload, and older versions of Photoshop do not recognise it. Converting to JPG solves all of that in one step, because JPG is the format everything has supported for thirty years. The trade-off is honest: both formats are lossy, so re-encoding costs a small amount of quality, and the JPG will be noticeably larger than the WebP was. Neither matters much for the situations that drive this conversion - you need a file the other system will accept, and compatibility is worth more than a few kilobytes. One thing to watch: if the WebP has a transparent background, JPG cannot keep it. Conversion runs in your browser.

Comment utiliser cet outil

  1. Add your WebP filesDrop them in or browse to select. Several can be converted at once.
  2. Set the qualityHigher preserves more detail from the source; around 85 keeps the re-encoding loss invisible.
  3. ConvertEach file is decoded and re-encoded as JPG in your browser - nothing is uploaded.
  4. DownloadThe JPGs open in any software, on any device, with no plugin required.

Pourquoi l’utiliser

  • Produces files that open everywhere - old software, print services, upload forms, every device.
  • Batch conversion, so a folder of downloaded images is one operation.
  • Runs on your device, so nothing is uploaded.
  • Originals preserved, so you keep the smaller WebP files if you want them.
  • No account, no limit and no watermark.

Usages courants

  • Opening an image saved from a website in software that will not read WebP.
  • Uploading to a form or portal that only accepts JPG or PNG.
  • Sending images to a print service that requires standard formats.
  • Sharing with someone on older software or an older device.
  • Importing into an application whose image support predates WebP.

Conseils pour de meilleurs résultats

  • Use a high quality setting - around 85 or above. You are re-encoding an already-compressed image, so keep the second pass light.
  • If the WebP has transparency you need, convert to PNG instead. JPG will fill it with solid colour.
  • Expect the JPG to be larger than the WebP. That is the format difference, not a conversion fault.
  • Keep the WebP if the image will also be used on a website - it is the better format there.
  • If the JPG then needs to be smaller for an upload limit, run it through the Image Compressor.

Erreurs à éviter

  • Converting at low quality, which stacks a second round of lossy compression on top of the first.
  • Converting a WebP with transparency to JPG and being surprised by the white background.
  • Converting website images back to JPG and re-uploading them to the site, undoing the speed benefit.
  • Assuming the JPG will be smaller. It will almost always be larger - that is why WebP exists.
  • Converting repeatedly between the two formats, which compounds the quality loss each time.

Add your WebP files above, choose a quality setting and convert. Each downloads as a JPG that opens in any software - all processed in your browser.

Yes. No account, no limit and no watermark.

Because a lot of software outside the browser still does not read WebP - older Windows photo viewers, some Photoshop versions, print services and plenty of upload forms. JPG is accepted everywhere.

A little, since both formats are lossy and this is a second encoding pass. At quality 85 or above the difference is not visible - keep the setting high because you are re-compressing already-compressed data.

No. JPG has no alpha channel, so transparent areas become a solid colour, usually white. Convert to PNG instead if the transparency matters.

Because WebP compresses more efficiently - typically 25-35% better at the same visual quality. The larger JPG is the price of universal compatibility.

No. Decoding and re-encoding happen in your browser, so the files stay on your device.

Yes. Add as many as you need and they are converted in sequence, then downloaded together.
