Compress Image to 100 KB
Squeeze any JPG, PNG or WebP under 100 KB without leaving your browser. Drop the file in and it works its way down to size — no upload, no sign-up, no watermark.

Your files stay in your browser. Nothing is uploaded.
A 100 KB cap almost never comes from you — it comes from a form that refuses to accept anything larger. Visa and passport portals, university applications, older job boards and government e-filing systems all tend to land on this number, and they usually say so only after you have already tried to upload.
What 100 KB actually costs you
This is a genuinely tight budget for a photograph. A modern phone picture starts somewhere between 3 and 8 MB, so getting under 100 KB means throwing away roughly 98% of the data. Expect visible softening in fine detail — hair, foliage, textured fabric — and some blotchiness in large areas of flat colour like a clear sky.
Two things help more than anything else. First, crop before you compress: pixels you delete cost nothing to store. Second, if the image is a logo, a scan or a screenshot rather than a photo, it will hit 100 KB easily and still look sharp, because flat colour compresses far better than photographic noise.
If it lands slightly over
The tool steps quality down until the file fits, but a very large or very detailed image can bottom out above the target. When that happens, resize it first — dropping a 4000-pixel-wide photo to 1200 pixels usually gets you under the line with quality to spare, because you are removing pixels instead of degrading them.

Frequently asked questions
- Why does an application form ask for 100 KB?
- Older upload systems store every submission on limited server space, so they cap each file. The number is about their storage, not about how your photo looks.
- Will my photo still be recognisable?
- Yes — faces and documents stay readable at 100 KB. What you lose is fine texture, which is rarely what these forms are checking.
- Is anything uploaded to make this work?
- No. The compression runs in your browser using a Web Worker, so the file never leaves your device. That matters when the image is an ID document.
