Image Format Converter
Convert an image between PNG, JPEG, and WebP. Runs entirely in your browser — nothing is uploaded to a server.
Click to upload or drag and drop
JPG, PNG, or WebP
Which format should I use?
- PNG — best for images with transparency or sharp edges (logos, screenshots, graphics)
- JPEG — best for photos; smaller files, no transparency support
- WebP — usually smaller than both at similar quality, with transparency support; supported by all modern browsers
A note on transparency
Converting a transparent PNG to JPEG fills the transparent areas with white, since JPEG has no transparency channel. Converting to WebP preserves transparency.
Frequently asked questions
What happens to transparency when converting to JPEG?
Transparent areas are filled with white, since JPEG has no transparency channel. Convert to PNG or WebP instead if you need to keep transparency.
Does WebP work in all browsers?
Yes — all current major browsers (Chrome, Firefox, Safari, Edge) support WebP for both viewing and this tool's conversion.
