How it works
For faster pages, smaller email attachments and upload limits.
JPG, PNG or WebP up to 50 MB. The file is opened by your browser and never uploaded.
Lower quality means a smaller file. Around 80 is a good starting point for photos; you can also resize at the same time.
You see the size before and after, plus how much was saved, and download the result.

In your browser. The picture is decoded, redrawn on a canvas and encoded again locally — it is never sent to a server.
For photographs, 70–85 usually looks the same as the original at a fraction of the size. For screenshots and flat graphics, keep it higher or convert to PNG.
PNG is lossless, so the quality setting does not apply to it. To make a picture like that much lighter, convert it to WebP or JPG.
