Compress an image to under 1MB
Set a 1MB target and the compressor hits it automatically — free, private, and processed entirely on your device.
Lots of forms, uploads and portals cap attachments at 1MB. Instead of guessing at a quality setting, set the target size to 1MB and this tool compresses your image to fit — while keeping it looking as good as possible at that budget.
It works on JPG, PNG and WEBP, handles batches, and never uploads your image, so it's safe for documents and personal photos alike.
