Convert Image Format
Convert between PNG, JPG and WebP. WebP gives the smallest file size; PNG keeps lossless quality.

How to Use the Format Converter
- Upload — Drag a PNG, JPG, or WebP file onto the drop zone (up to 20MB), or click to browse.
- Pick the target format — Choose JPEG, WebP, or PNG from the "Convert to" dropdown.
- Set quality — For JPEG and WebP, drag the quality slider (default 90) or type an exact value. PNG is lossless and ignores this setting.
- Download — Watch the converted file size update in real time, then save the result.
PNG vs JPG vs WebP — Which Format Should You Choose?
Each format wins somewhere. PNG is lossless and supports transparency, so it's right for screenshots with crisp UI text, logos, and anything you'll edit again — but files are big. JPEG is the universal photo format: small files, no transparency, and visible artifacts if you push quality too low. WebP is the modern middle ground, typically 25–35% smaller than JPEG at the same visual quality, with transparency support — and every current browser, Discord, and most CMSs accept it. For sharing game screenshots, WebP at quality 80–90 is hard to beat; for archiving, keep the PNG.
Why Convert Instead of Just Renaming the File?
Changing a file extension doesn't change the data inside — a renamed PNG is still a PNG, and strict apps will reject it. Real conversion re-encodes the image, which is what actually shrinks the file or adds compatibility with software that refuses certain formats.
Frequently Asked Questions
What happens to transparency when I convert PNG to JPEG?
JPEG doesn't support transparency, so transparent areas are flattened onto a solid background. Choose WebP or PNG output if you need to keep the alpha channel.
Why is my converted file bigger than the original?
Converting a compressed format (like JPEG) to a lossless one (PNG) stores every pixel exactly, which takes more space. To shrink files, convert toward JPEG or WebP instead.
Are my images uploaded for conversion?
No — conversion runs locally in your browser with the Canvas API. Free, no signup, and your files never leave your device.
