How to Convert WebP to JPG So Any App Can Open It
Images saved from websites often arrive as WebP files that older apps and forms reject, so here's how to convert them to JPG or PNG in your browser.
To convert a WebP image to JPG, open a converter, drop in the .webp file, choose JPG and download the result. ImageSpark's WebP to JPG page does this in your browser in a couple of clicks: any transparent areas get a clean white background, you can adjust the quality, and the image never leaves your device. If you need to keep a transparent background, convert to PNG instead.
This guide explains why so many downloaded images turn out to be WebP, how to convert them properly, and when it's better to leave them as they are.
Why do images download as WebP?
WebP is an image format designed for the web. It produces smaller files than JPG or PNG at a similar visual quality and supports transparency, so pages load faster. Because every major browser displays WebP, many websites and content delivery systems automatically serve images as WebP.
When you right-click an image and save it, you get the file the site actually sent, which is often a .webp file. That's fine for viewing in a browser, but plenty of other software is less accommodating. Older photo editors, some office apps, printing kiosks, online print services, email clients and upload forms may refuse the file or show nothing at all.
How to convert WebP to JPG
1. Open the converter. Go to WebP to JPG. JPG is already selected as the output format.
2. Add the WebP file. Drag it onto the page or click to choose it. You can also convert JPG, PNG, AVIF, GIF, BMP and SVG files with the same tool.
3. Check the quality. The quality slider starts high, which keeps the image looking the same. Lower it only if you need a smaller file.
4. Convert and download. Click Convert and save the JPG. It keeps the same width and height in pixels as the original.
The whole process happens in your browser, so it's quick even for large images and works on phones as well as computers.
Convert WebP to PNG to keep transparency
JPG doesn't support transparency, so a WebP logo, sticker or product cut-out with a see-through background gets a white background when saved as JPG. If you want to keep the transparency, use WebP to PNG instead. PNG keeps the see-through areas exactly as they were and is lossless, which also makes it the better choice if you plan to edit the image.
The trade-off is size. PNG files are usually larger than both the WebP and a JPG version, especially for photos.
Can you open WebP without converting it?
Often, yes. Web browsers display WebP, and the built-in image viewers on Windows and macOS generally open it too. So if you only want to look at an image, you may not need to convert it at all; try opening it with your browser.
Converting is worth it when you need the image to work somewhere else, for example:
- Uploading to a form or marketplace that only accepts JPG or PNG
- Sending it to someone whose email app or phone gallery can't show it
- Editing it in software that doesn't read WebP
- Printing it at a shop or through an online print service
- Adding it to a document or presentation that won't embed WebP
Tips for better conversions
- Don't just rename the file. Changing photo.webp to photo.jpg doesn't convert anything. The data inside is still WebP, and many apps will refuse to open it or show an error.
- Expect the JPG to be larger. WebP is more efficient, so the same picture usually takes more space as a JPG. If you need a smaller file afterward, compress the JPG.
- Animated WebP files become still images. A JPG can't hold animation, so only the first frame is converted.
- Convert once, from the best copy. Every JPG save discards a little detail. If you have a higher-quality version of the image, start from that.
- Respect the rights to the image. Saving and converting an image from a website doesn't give you permission to reuse it. Use images you own or have the right to use.
When you should keep WebP
If you're publishing images on your own website, WebP is usually the better format, not the worse one. The files are smaller, pages load faster, and every major browser supports it. In that case, the conversion goes the other way: use JPG to WebP to turn your JPG and PNG images into WebP before uploading them to your site.
A sensible rule of thumb is WebP for the web, and JPG or PNG for everything else: email, printing, documents and upload forms.
Converting lots of WebP files
On the free plan you convert one image at a time, which is plenty for the occasional download. If you regularly deal with folders of WebP images, for example product photos from a supplier's website, batch conversion is available on Pro, so you can convert a whole set with the same settings in one go.
FAQ
Is WebP better quality than JPG?
At the same file size, WebP usually looks a little better than JPG, and it supports transparency. At the same visual quality, it's smaller. Its only real drawback is compatibility with older software and forms.
Why is my JPG bigger than the WebP it came from?
WebP compresses images more efficiently than JPG, so the same picture needs more bytes as a JPG. That's normal. Lower the JPG quality slightly or compress it afterward if you need a smaller file.
Can I just change the file extension from .webp to .jpg?
No. Renaming doesn't change the data inside the file. Some apps may open it anyway, but many won't, and upload forms often detect the real format. Convert it properly instead.
Are my images uploaded when I convert them?
No. The conversion happens in your browser on your own device, so nothing is sent to a server.
