Image Format Converter
Convert PNG, JPEG and WebP locally — nothing is uploaded.
Which image format should you choose?
WebP offers the best compression for the web and is supported everywhere modern; JPEG is the safe universal choice for photos; PNG is lossless and the only one of the three that keeps transparency. Converting is done through the browser's canvas engine on your device — the file is never sent anywhere.
Converting a PNG screenshot to WebP typically cuts its size by half or more. Going the other way (WebP → PNG) increases size but buys you compatibility with old tools and lossless editing. When converting to JPEG, transparency is flattened onto the background color you see in the preview.
FAQ
Does converting lose quality?
Moving to a lossy format (JPEG, WebP) re-encodes the image; at quality 90 the difference is invisible. Moving to PNG is lossless but cannot restore quality already lost in earlier conversions.
Is AVIF supported?
Browsers can display AVIF but most cannot encode it via canvas yet. Use WebP for the best size/compatibility balance today.
