Convert WebP Images to Classic JPG

Decodes WebP with your browser and re-encodes it as JPG at an adjustable quality, flattening any transparency onto a background colour you choose. Converted in the tab, with nothing uploaded.

About the WebP to JPG Converter

WebP is everywhere on the modern web because it makes small files, but it still trips up plenty of software: older photo editors, some print services, various document tools and a fair few applications will not take a WebP and want a JPG instead. This converts by decoding the WebP in the browser and re-encoding it as a JPG.

Two settings are exposed. Quality is the JPG quality slider, at 90 percent by default. And because WebP can be transparent while JPG cannot, a background colour picker sets what fills any transparent areas — white unless you choose otherwise. If your WebP is a plain photograph with no transparency, the background setting simply never comes into play.

Key Features

  • Adjustable quality: A slider defaulting to 90 percent lets you trade file size against fidelity for the particular image.
  • Background colour for transparency: Transparent WebP areas are flattened onto a colour you pick, since JPG has no alpha channel — white by default.
  • Universal compatibility: JPG is accepted by effectively every application and service, which is the reason to convert away from WebP.
  • Batch conversion: Add several WebP files and each is converted, returned as a ZIP.
  • Handles both WebP kinds: Whether the WebP was saved with lossy or lossless compression, the browser decodes it and the output is a standard JPG.
  • Converted privately: Decoding and JPG encoding both run in this tab, so an image is not uploaded to a conversion site to change its format.

How to Use the WebP to JPG Converter

  1. Add one or more .webp files.
  2. Set the quality, and a background colour if the image has transparency.
  3. Press Convert Now.
  4. Download the converted JPG, or a ZIP of the set.

How It Works

WebP decoding uses the browser's native support, which is universal on current browsers, so this is reliable in a way the HEIC conversion is not. The decoded pixels are flattened onto the chosen background and encoded as JPG at your quality setting.

The conversion is a re-encoding from one lossy format to another, and that has a consequence worth understanding. A WebP saved with lossy compression has already discarded some detail; encoding it again as JPG discards a little more, because the two formats compress differently and neither is a perfect fit for the other. At 90 percent this second loss is hard to see, but converting back and forth repeatedly between lossy formats will visibly degrade an image over several rounds. Convert once, from the best source you have, rather than round-tripping.

As with any move to JPG, transparency cannot survive — a transparent WebP has those areas filled with the background colour. If keeping transparency matters, WebP to PNG is the conversion you want instead, since PNG has an alpha channel and JPG does not.

When You Need It

A journalist has been sent photographs as WebP by a source, and the newsroom's publishing system only ingests JPG. Converting lets the images run with the story. The photographs came from a source who expects discretion, so converting them on the reporter's own machine rather than through an online tool keeps material tied to a confidential source off any third-party server.

An online seller saves product photos from a supplier's site that serves WebP, and the sales platform requires JPG for listings. Converting the batch produces upload-ready images. The supplier relationship and pricing behind the products are commercially sensitive, so a local conversion avoids exposing which supplier's catalogue the images came from.

FAQ

Frequently Asked Questions

Will converting WebP to JPG reduce the quality?
A little. Both are lossy formats that compress differently, so re-encoding a WebP as JPG discards a small amount of additional detail. At 90 percent it is difficult to notice on a single conversion. What harms an image is repeatedly converting back and forth between lossy formats, so convert once from the best original you have rather than round-tripping.
My transparent WebP got a solid background.
JPG cannot store transparency, so the transparent areas are filled with the background colour — white unless you set another. If you need the transparency kept, convert to PNG instead using the WebP to PNG tool, since PNG supports an alpha channel where JPG does not.
Does it handle lossless WebP as well as lossy?
Yes. The browser decodes both kinds of WebP, and the output is a standard JPG either way. Note that converting a lossless WebP to JPG does introduce lossy compression, since JPG has no lossless mode — if preserving every pixel matters, PNG is the better destination.
What quality setting should I use?
For photographs, 90 percent is a good default that keeps the image crisp at a reasonable size. You can drop to around 75 for images that are only viewed on screen and halve the file again with little visible difference. For anything with sharp edges or text, keep it high, since JPG compression is unkind to hard edges.
Can I convert a whole folder of WebP images?
Yes. Add them all and each is converted, delivered as a ZIP when there is more than one. The batch is limited only by your device's memory, since each image is decoded in full during conversion.
Are my WebP images uploaded to be converted?
No. The WebP is decoded by your browser and re-encoded as JPG in this tab, with nothing sent to a server. This matters when the images come from a confidential source or a commercial relationship you would not want an external converter to have a record of.
