Choosing the right image format is one of the easiest performance wins on the web. The Image Format Converter lets you switch any image between PNG, JPG and WebP, tune the quality, and see the resulting file size before you download.
Which format should you use?
- JPG — photographs and complex imagery where small file size matters
- PNG — graphics with transparency, sharp edges, or text
- WebP — a modern format that usually beats both on size at the same quality
Lossy vs lossless
PNG is lossless: it preserves every pixel exactly, which is why the quality slider does not apply to it. JPG and WebP are lossy: they discard information the eye is unlikely to notice in exchange for much smaller files. The quality slider controls how aggressive that trade-off is.
Tip: converting a large PNG photo to WebP at around 80% quality often cuts the file size by 60–80% with no visible difference.
How to use the Image Format Converter
- Drag in or select an image.
- Choose the output format: PNG, JPG or WebP.
- Adjust the quality slider for JPG or WebP and watch the size update.
- Download the converted file.
All conversion happens in your browser using the canvas API, so nothing is uploaded. Use WebP for the web, JPG for broad compatibility, and PNG when you need transparency or pixel-perfect graphics.
