FreeImageKit compresses photos to 100 KB or less for free, in your browser, without uploading them. It fits each photo inside 2,048 px on its longest side, then searches for the highest JPG quality that stays at or under 100 KB, so a whole batch meets the limit in one pass. Use it for upload forms, email and websites with a 100 KB cap.

Never over the limit
If a photo cannot reach 100 KB at these settings, you get a message instead of a file that is too large.
Frequently asked questions
How do I compress many photos to 100 KB at once?
Select them all. Each photo gets the same 2,048 px limit and its own quality search, and you can download every result as one ZIP.
Will it look good at 100 KB?
For a photo shown on a screen, usually yes. A very detailed photo at 2,048 px may show some softness; reduce its size with Customize if you only need it smaller.
Does 1 KB mean 1,000 or 1,024 bytes here?
1,024 bytes, like most file managers. A few forms count 1 KB as 1,000 bytes, which is about 2% less; for those, choose Customize and set the target a little lower, for example 48 KB instead of 50 KB.
Are my photos uploaded?
No. Resizing and the quality search run in your browser, so the photos never leave your device. It is free, with no sign-up and no watermark.
