JPG to WebP Converter
To turn a JPG into a WebP, decode the JPG and save the pixels as WebP, here at quality 80 unless you change it. At a similar look a WebP is often noticeably smaller, which helps pages load faster. Both formats are lossy, so convert from the original JPG once. Nothing is uploaded.
How to use
- Drop one or more images onto the box, or press it to choose files. HEIC, HEIF, WebP, AVIF, PNG, JPG, GIF, BMP and TIFF are accepted, up to 50 MB each.
- Pick the output format, then set the quality. For JPG, choose the background that fills transparent areas. EXIF (camera, date, GPS location) is removed unless you tick the box to keep it.
- Check the sizes, then press Download on each file, or Download all (ZIP) when you converted several.
How it works
Each file is read by your browser, or by the libheif decoder for HEIC, and drawn on a canvas as plain pixels. The canvas is then saved in the format you chose. Because the pixels are decoded and encoded again, converting between lossy formats such as JPG and WebP adds a small loss each time, so keep the original and convert from it once.
JPG, WebP and AVIF use the quality slider: a lower number gives a smaller file with more visible blocks and blur. PNG is lossless and ignores it, so its size depends on the picture, and photos are usually much larger as PNG than as JPG. JPG has no transparency, so clear areas are filled with the background color you pick, white by default.
Saving through a canvas drops all metadata. If you keep EXIF, the tool copies the EXIF block of the original into the new JPG, PNG or WebP and sets its Orientation tag to 1, because the pixels are already turned upright. AVIF files cannot carry it here. Animated GIFs use their first frame.
Which format to choose
| Format | Good for | Transparency | Size for a photo |
|---|---|---|---|
| JPG | Photos, forms, email, any device | No | Small |
| PNG | Screenshots, logos, graphics | Yes | Large |
| WebP | Photos and graphics on websites | Yes | Smaller than JPG |
| AVIF | Websites that want the smallest files | Yes | Smallest |
FAQ
Why use WebP instead of JPG?
WebP usually gives a smaller file at a similar look, so a page loads faster and uses less data. It also supports transparency, which JPG does not.
Can every browser and app open WebP?
All current browsers show WebP. Some older image editors, email clients and print services cannot, so keep the JPG for those uses.
Will the picture lose quality?
Both JPG and WebP are lossy, so a second lossy save loses a little more detail. Convert from the original JPG once instead of converting the same file again and again, and check the result at quality 80.
What happens to the EXIF data?
It is removed by default, including the GPS location. Tick the keep box to copy it into the WebP. The orientation tag is reset because the pixels are already upright.
Can I convert many photos at once?
Yes. Add as many files as you like, each up to 50 MB, and press Download all (ZIP) to get them in one file.
