FreeImageKit compresses a photo to 50 KB or less for free, in your browser, without uploading it. It fits the photo inside 1,600 px on its longest side, then searches for the highest JPG quality that stays at or under 50 KB. Use it for application and profile uploads with a 50 KB cap; if the form also sets exact pixel dimensions, resize to those first.
How to use this page
- Select one or more photos (JPG, PNG, WebP or HEIC) and choose Run.
- Each photo is fitted inside 1,600 × 1,600 px, then saved as the highest-quality JPG at or under 50 KB.
- Download each image, or all of them as a ZIP, and check the file sizes.

Never over the limit
If a photo cannot reach 50 KB at these settings, you get a message instead of a file that is too large.
Frequently asked questions
Why is the result smaller than 50 KB?
The search keeps the best quality at or under the limit, so the file usually lands a few KB below 50. It never goes over when the target can be reached.
Should I compress or resize to 50 KB?
Compress keeps up to 1,600 px and lowers quality; Resize Image to 50 KB fits the photo into 1,024 px so it stays sharper. Pick resize for photos that will be shown small, such as a profile or ID photo.
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.
