JPG, PNG, WebP. Stays on your device, nothing is uploaded.
Your converted image will appear here once generated.
PNG is lossless (larger files, supports transparency). JPEG and WebP are lossy with a quality slider (smaller files, no transparency for JPEG). WebP usually beats JPEG at the same visual quality, but JPEG has the widest compatibility.
Common questions
Which format should I pick?
PNG for screenshots, logos, or anything needing transparency. JPEG for photos where small file size matters more than perfect quality. WebP for the best of both, smaller than JPEG at equivalent quality, if you don't need to support very old software.
Will converting to JPEG lose transparency?
Yes, JPEG has no alpha channel. Transparent areas are filled with white before converting. If you need to keep transparency, convert to PNG or WebP instead.
Does this upload my image anywhere?
No. The conversion happens entirely in your browser using the canvas API. Nothing about your image is sent anywhere.
