How to Open and Convert WEBP Images to JPG or PNG

You right-click an image on a website, choose "Save image as", and the file ends in .webp. Then you try to open it in an editor, drop it into a document or upload it to a form, and it fails: "unsupported format". It's one of the most common annoyances when saving images from the web.

This guide explains what WEBP is, why it shows up so often, and how to convert it to JPG or PNG in a few seconds, in your browser.

What WEBP is

WEBP is an image format created by Google for the web. According to Google's official developer documentation (checked in October 2026), WEBP offers lossy and lossless compression, supports transparency (alpha channel) and also supports animation. Google states that its lossless images are 26% smaller than PNGs and its lossy images are 25–34% smaller than comparable JPEGs. Those are Google's figures, not our measurements.

In short, WEBP makes web pages load faster. That's why many sites serve their images in this format, and when you save an image from your browser, you sometimes end up with a WEBP instead of a JPG or PNG.

Why your app won't open it

The same Google documentation says WEBP is natively supported in the major browsers: Chrome, Safari, Firefox, Edge and Opera. That's why the image looks perfect on the website.

The trouble starts outside the browser:

• Some editing programs, older image viewers and office apps won't open it or let you insert it.
• Many portals and forms only accept JPG or PNG in their upload fields.
• Some messaging apps and social platforms may display it oddly or reject it.

The simplest fix is converting it to a universal format: JPG or PNG.

JPG or PNG: which one?

If the image is…	Convert to	Why
A photo (people, places, products)	JPG	Smaller, and accepted almost everywhere
A logo, icon or graphic with a transparent background	PNG	Keeps the transparency
A screenshot with text	PNG	Sharp edges, no compression smudges
Not sure	PNG	No quality loss; you can compress later

Watch out for transparency

JPG doesn't support transparency. If you convert a WEBP with a transparent background (a logo, for example) to JPG, the transparent areas are filled with white. If you need to keep the background transparent, choose PNG.

Step by step: WEBP to JPG

1. Open WEBP to JPG on your phone or computer.
2. Select one or more .webp files.
3. Adjust the JPG quality if you want. Higher quality means a bigger file.
4. Convert and download. Several results download together as a ZIP, or one by one.

Step by step: WEBP to PNG

1. Open WEBP to PNG.
2. Select your files.
3. Convert and download. Transparency is kept.

To choose the output format yourself (JPG, PNG or WEBP), or to convert other formats such as GIF or BMP, use Convert Image.

Animated WEBP: you get a still image

WEBP can be animated, like a GIF. ConvertirDocs converts still images, so an animated WEBP comes out as a still image: the first frame of the animation. If you need the full animation, this isn't the right tool. If a representative picture is enough, the first frame usually does the job.

After converting

• If the file is too big (common with large PNGs), use Compress Image. Choose high, medium or low quality, or type a target size in KB. For PNGs, it reduces the colors to a palette of up to 256, which helps with screenshots and graphics; for photos, converting to JPG is the better move.
• If you need different dimensions, set the pixels with Resize Image.
• If you need a PDF, JPG to PDF takes JPG, PNG and WEBP directly.

With "What else do you want to do with this file?" you send the result to the next tool without picking it again.

Privacy

The conversion runs in your browser: the image isn't uploaded to any server. Processing also removes EXIF data (such as GPS location, if there is any) and respects the camera orientation.

Copyright: converting doesn't give you permission

Changing an image's format doesn't change who owns it. An image being online doesn't mean you're free to use it. Before using someone else's image on your website, in your business, in a post or in print, check its license or ask the creator for permission. If you need images you can use without worry, look for stock libraries with clear licenses, or use your own.

FAQ

Can I stop my browser from saving as WEBP? It depends on the site: the server decides which format to send you. The practical answer is to convert afterwards.

Does converting WEBP to JPG lose quality? JPG is lossy, so a little is lost. At high quality you won't see it. If you want zero loss, use PNG.

Can I convert many images at once? Yes. Select several and download them as a ZIP.

My animated WEBP turned into a still image. Is that a bug? No. Animations come out as a still image showing the first frame.

Do I need to install anything? No. It works in modern browsers on phones and computers.

Summary

WEBP is designed to make websites load fast, but many apps and forms don't accept it. Convert it with WEBP to JPG for photos, or WEBP to PNG when it has transparency or text. Remember that animated WEBPs come out as a still image, and that converting an image doesn't give you the right to use it.
