Free image and PDF tools that run in your browser: HEIC to JPG, compress, resize and crop images, merge, split and convert PDFs. No upload, no account, no daily limit.

What to expect from an ideal product
- UploadOff compresses images inside your browser, on your own computer or phone, so the photo is never sent to a server.
- Pick "under 200 KB" in the size menu, drop your images, and each one comes back under that size. The menu also has 2 MB, 1 MB, 500 KB, 100 KB, 50 KB and 20 KB for forms with other limits.
- It tries a little more compression first, which the eye hardly notices, so each picture stays as sharp as the 200 KB limit allows.
- Drop several images at once and save them one by one or all together in a single ZIP file. There is no sign-up and no daily limit.
- Photos, including HEIC pictures from an iPhone, come back as JPG and WebP files stay WebP, so the result is ready for upload forms that ask for a small photo.
