Compress Image to 100KB
Meet the 100KB photo limit on job portals, college applications, and upload forms. Free, private, in your browser.
Need batch processing or bigger files? Download Compresso for folders, big videos, and offline compression.
100KB is the most common photo limit on the internet's forms: job portals, college applications, internship sites, membership directories. If a form just rejected your photo, this is the fix: drop it, download it under 100KB, carry on.
The tool works in steps, easing quality down and shrinking dimensions only as far as the target demands. A portrait at 100KB still looks sharp at the sizes these portals display, and the output is checked against the limit before you get it.
Nothing is uploaded anywhere. The compression runs in your browser, so an application photo stays as private as the rest of the form you are filling in. For batches, the Compresso app on Mac and Windows handles folders offline.
Frequently Asked Questions
Why is 100KB such a common limit?+
It is the default photo cap on most job boards, college admission portals, and corporate directories: small enough to store millions of photos, big enough to recognize a face.
Does a 100KB photo look good?+
Better than people expect. At the sizes these sites show your photo, a well-compressed 100KB portrait is effectively indistinguishable from the original.
What image formats can I use?+
JPG, PNG, and WebP all work. Most portals want JPG, so if your PNG needs converting to hit the target, the tool does it and says so.
Do you keep or see my photo?+
No. The compression runs on your device and the file never leaves it. There is nothing on a server to keep.
