Compress images without uploading them
Drop in a PNG, JPG or WebP and the tool shrinks it right in your browser, then shows you exactly how many kilobytes you saved. Drag the Quality slider to trade a little sharpness for a much smaller file, perfect for speeding up a website or fitting an email attachment. Because everything runs locally, there is no upload wait and no size cap.
Convert between PNG, JPG, WebP and HEIC
Set Output format to turn a PNG into a JPG, a JPG into modern WebP, or anything in between. WebP typically cuts file size by a third or more over JPG at the same quality, which is why it is the format to reach for on the web. Transparent PNGs get a clean white background when saved as JPG.
Dropped an iPhone photo? HEIC and HEIF files are decoded right here and converted to a JPG, PNG or WebP you can actually open anywhere. The HEIC is still read and converted entirely in your browser, nothing is uploaded.
Resize in bulk
Use Resize to cap the longest side to a pixel size, say 1920px for a web banner, or scale everything by a percentage. Load up to 50 images, set it once, and download them one by one or all at once.
Everything happens on your device. No image is uploaded, stored or seen by anyone, the files never leave your browser.
