How to convert an image
- Add JPG, PNG, WebP, GIF or BMP images.
- Pick the format you want.
- For JPG and WebP, adjust the quality if needed. For JPG, choose the colour that replaces transparent areas.
- Download the converted files.
Which format should I choose?
- JPG for photographs that must open everywhere. No transparency.
- PNG for screenshots, logos and graphics with sharp edges or transparency. Files are larger.
- WebP for websites: smaller than JPG and PNG with transparency support, and readable by all current browsers.
Questions about the Image Converter
Why does my transparent PNG get a white background as a JPG?
JPG cannot store transparency, so transparent pixels need a colour. White is the default and you can change it with the background colour option.
Can I convert animated GIFs?
Only the first frame is converted. The result is a still image.
Is there a limit?
Up to 20 images at a time, 25 MB each. Because the work happens on your device, very large images depend on how much memory your browser has available.
