Why compress to 100 KB?
Many online application and exam portals cap the photo or document file size — and a 100 KB limit is one of the common requirements. A picture straight from your phone is far larger than that, so it gets rejected at upload. This page presets the compressor to 100 KB, so you just upload your image and download a version that fits.
The compression runs in your browser using a smart quality search, keeping your photo as sharp as possible while landing at or under 100 KB. Your file is never uploaded.
Frequently asked questions
How do I compress an image to 100 KB?
Upload your photo above, make sure the target is set to 100 KB, and click Compress. The tool reduces the quality just enough to bring the file at or under 100 KB, then lets you download it.
Will the image still be clear at 100 KB?
Yes, in most cases. The tool keeps the highest quality possible while meeting the 100 KB limit. Smaller targets naturally reduce quality more, but the result stays fine for passport-style photos and document uploads.
Is my image uploaded to a server?
No. The compression happens entirely in your browser, so your file never leaves your device.
Is it free?
Yes — completely free, no signup, no watermark.
Need a different size?
Compress to any KB target, or resize to exact dimensions.
