JPG vs PNG vs WebP
| Feature | JPG | PNG | WebP |
|---|---|---|---|
| Compression | lossy | lossless | lossy and lossless |
| Transparency | no | yes | yes |
| Animation | no | APNG | yes |
| Photo file size | small | large | smallest |
| Compatibility | everywhere | everywhere | browsers, newer apps |
| Best for | photos, sharing, print | graphics, logos, screenshots | websites |
Which format should you choose?
- Website or online shop → WebP (75-85% quality). The smallest files and faster loading.
- Email, printing, official forms → JPG. Everyone can open it.
- Logo, icon, transparent graphic for editing → PNG.
As input, the converter accepts every format your browser can display - besides JPG, PNG and WebP also GIF, BMP, ICO, SVG and, in newer browsers, AVIF. iPhone HEIC files currently open only in Safari; in other browsers use the HEIC to JPG converter.
What happens to the file during conversion?
| Conversion | File size | Transparency |
|---|---|---|
| JPG → WebP | usually 25-35% smaller | none in source |
| PNG → WebP | often several times smaller | kept |
| PNG → JPG | 3-10× smaller (photos) | replaced with background colour |
| WebP → JPG | usually larger | replaced with background colour |
| WebP → PNG | several times larger | kept |
| JPG → PNG | 3-8× larger | none in source |
In every case the pixel dimensions stay the same. Converting to a lossy format (JPG, WebP) uses the slider quality - 85% by default. Saving to PNG is lossless relative to the decoded image but cannot recover detail lost earlier. Each file shows its size before and after, plus a warning if the result is bigger than the original. If you only want a smaller file in the same format, use the image compressor.
Typical mistakes are converting back and forth between lossy formats (JPG → WebP → JPG), saving simple graphics and screenshots with text as low-quality JPG, and expecting PNG to “sharpen” a photo. The best result always comes from converting the original file, in one step, straight to the target format.
Privacy
Conversion runs entirely in your browser (Canvas API). Files are never sent to a server, so you can safely convert private photos, scans and company graphics. Saving to a new format also strips EXIF metadata, including GPS coordinates.
