Convert JPG, PNG and WebP images
Some websites only accept JPG, a design needs a PNG with transparency, or you want smaller WebP files for your blog. This image converter switches images between JPG, PNG and WebP in one go — choose several files, pick the format and download the results. Transparent PNGs get a solid background when converted to JPG, and the whole process runs on your own device.
How to use it
- Choose one or more images (JPG, PNG, WebP, GIF or BMP).
- Select the output format and quality.
- For JPG output, pick a background colour for any transparent areas.
- Tap Convert and download each file.
Which format should you choose?
| Format | Best for | Transparency |
|---|---|---|
| JPG | Photos, forms that only accept .jpg | No |
| PNG | Screenshots, logos, text, graphics | Yes |
| WebP | Websites and sharing — smallest files | Yes |
Example
A 2.4 MB PNG screenshot of a photo converted to JPG at 90% quality typically becomes around350 KB; as WebP, around 250 KB. A logo with a transparent background should stay PNG or WebP — converted to JPG it would get a white box behind it.
To also shrink the size, use the image compressor; to change dimensions, use the image resizer.
