Image Converter: WebP, JPG & PNG
Turn WebP images into JPG or PNG, or make WebP files from your JPGs and PNGs. Add one image or a whole batch, choose the target format, and download the results one by one or together in a ZIP file.
Your images are converted inside your browser and are never uploaded to our server. The ZIP library is downloaded from the jsDelivr CDN; your files are not.
How to use the Image Converter
- Drop one or more images onto the box, or click it to choose them. You can keep adding files; each one appears in the list.
- Choose the format to convert to: JPG, PNG or WebP. For JPG and WebP, set the quality (higher means a larger file with more detail).
- Press Convert. Each file shows its new size and gets its own Download button.
- With two or more images, press Download all as ZIP to save them in one file.
Which format should you pick?
- JPG is the safe choice when an app, printer or upload form refuses WebP. It suits photographs, but it cannot store transparency and it blurs sharp edges such as text at lower quality settings.
- PNG is lossless: every pixel is kept exactly, and transparency is preserved. That makes it right for screenshots, logos and diagrams, and heavy for photos.
- WebP handles photos and graphics, supports transparency and is widely used on web pages. Whether it beats JPG or PNG on size depends on the picture, so compare the sizes this page shows after converting. Check first that the place you are sending the image accepts WebP.
How the conversion works
Each image is opened by your browser, drawn onto a canvas at its full original size, and saved again with the browser's own encoder. The pixel dimensions do not change. Converting to PNG keeps every pixel as decoded; converting to JPG or WebP is lossy, so a little detail is lost each time. Converting a JPG to PNG cannot bring back detail the JPG already discarded, it just stores the same picture in a bigger file.
The files are processed one after another so that a large batch does not exhaust your device's memory all at once. If two images would end up with the same name, a number is added to the second one so nothing is overwritten in the ZIP.
Limitations to know about
- Metadata is removed. The saved files contain no EXIF data (camera, date, GPS location) and no embedded color profile.
- Animation is lost. Animated GIF and animated WebP files are converted as a single still frame.
- Transparency becomes white in JPG. Choose PNG or WebP to keep transparent backgrounds.
- Only formats your browser can open. iPhone HEIC photos, TIFF and RAW files usually cannot be read by browsers, so they show "Could not open this image".
- WebP saving depends on the browser. If your browser cannot write WebP, the page tells you and saves PNG instead rather than pretending.
Frequently asked questions
Are my images uploaded to convert them?
No. The conversion happens in your browser on your own device. Only the small ZIP library is fetched from a public CDN; your pictures never leave your computer or phone.
How do I open a WebP file that my program won't accept?
Convert it to JPG (for photos) or PNG (for graphics or anything with transparency) here, and use the converted file instead. Most image viewers and editors open both.
Will converting reduce the image quality?
Converting to PNG does not lose anything further. Converting to JPG or WebP is lossy, so some fine detail is discarded; at high quality settings the difference is often hard to see, but check images with text or fine lines.
Can I convert many images at once?
Yes. Add as many as you like and press Convert once. They are processed one by one in your browser, so a very large batch takes longer and, on a phone, may run out of memory. Then download them individually or as a single ZIP.
Does it change the size of my images?
No, the width and height stay exactly the same. Only the file format and the file size change. To change the dimensions, use Resize Image.
