Converted entirely in your browser with <canvas> — your image is never uploaded.
PNG for transparency, JPEG for photos, WebP for both at smaller sizes.
Different image formats trade off quality, file size, and features. PNG is lossless and supports transparency (great for logos, screenshots, UI). JPEG is lossy and compact (great for photos, no transparency). WebP does both — transparency and strong compression — and is widely supported today.
This converter loads your image into a <canvas> and re-encodes it with canvas.toBlob(), entirely in your browser — nothing is uploaded. It reads PNG, JPEG, WebP, AVIF, and GIF (first frame for animated GIFs) and writes PNG, JPEG, or WebP; the quality slider applies to the lossy formats. Converting a transparent image to JPEG fills the background white, since JPEG has no alpha channel.
