Convert Between JPG, PNG, and WebP
Different jobs want different image formats: JPG for small photos, PNG for sharp graphics and transparency, WebP for the best size-to-quality ratio on the modern web. This tool converts any image to the format you need — PNG to JPG, JPG to WebP, and every other combination — with a quality slider for the lossy formats.
Conversion runs on a canvas in your browser. Everything runs on your device via open-source browser libraries — your file is never uploaded. You can verify it yourself.
Frequently Asked Questions
JPG for photographs, PNG when you need crisp edges or transparency, and WebP when you want the smallest file at good quality (great for websites).
For JPG and WebP it trades file size against fidelity — lower means smaller. PNG is lossless, so the slider does not affect it.
Converting a transparent PNG to JPG fills the background white (JPG has no transparency). Convert to WebP or keep PNG to preserve transparency.
No — the conversion happens entirely in your browser and the image is never sent anywhere.
