Convert any image to the right format
Different formats exist for different jobs: WebP and AVIF for lightweight web delivery, PNG for lossless graphics and transparency, JPEG for universally-compatible photos. This converter re-encodes each image on an HTML5 canvas at the quality you choose, so you can switch WebP to JPG, PNG to WebP, or JPG to PNG without installing software or uploading anything.
Batch, private, and honest about support
Drop a whole folder of images and convert them together, then download each one or all at once. Because encoding runs in your browser, the tool detects which formats your browser can actually produce and disables the rest — so you never get a silently-broken file. Every image is processed locally and never sent to a server.
