How the image format converter works
The converter draws your image onto a canvas, then re-encodes it using the target format's encoder. JPEG and WebP are lossy and support a quality setting; PNG is lossless, so the quality slider doesn't apply when converting to PNG.
Step-by-step guide
- Choose an image file from your device.
- Select the format you want to convert to.
- Adjust quality if converting to JPEG or WebP.
- Download the converted file.
Choosing the right format
| Format | Best for | Transparency |
|---|---|---|
| JPEG | Photos, smaller file size | No |
| PNG | Logos, graphics, screenshots with text | Yes |
| WebP | Modern web use, smallest file size | Yes |
Frequently asked questions
JPEG files are typically much smaller than PNG for photos, since JPEG uses lossy compression while PNG doesn't. Convert to JPEG when you don't need transparency and want a smaller file.
PNG supports transparency (an alpha channel) and lossless quality, useful for logos, icons or graphics with sharp edges and text where JPEG's compression artifacts would be visible.
WebP generally compresses more efficiently than JPEG or PNG at comparable visual quality, but actual results vary by image content — check the output size for your specific file.
No — once JPEG compression has discarded detail, converting to a lossless format afterward can't recover it. It will only stop further loss from that point on.
