Make your image smaller than 100 KB

Many online application forms, including job portals, university admissions, exam registrations and government services, only accept images under 100 KB. A photo straight from a phone is usually 2–5 MB, so it gets rejected. This tool brings it under 100 KB while keeping it as sharp as possible.

How it works

  1. Upload your image — drop one or more photos or scans into the box above. JPG, PNG and WEBP are accepted.
  2. Pick your target size — the first option is selected for you.
  3. Resize and download — the tool finds the best quality that fits. One file downloads as a JPEG; several download together as a ZIP.

Common uses

Under 100 KB vs 50–100 KB

“Under 100 KB” gets the file below the limit as safely as possible. “50–100 KB” is better when a form also rejects files that are too small or blurry: the tool keeps the file as close to 100 KB as it can, which means more detail.

Frequently asked questions

How do I reduce a photo to 100 KB?

Upload the photo, keep “Under 100 KB” selected and click Resize Image. The tool lowers JPEG quality step by step, and only shrinks the dimensions if needed, until the file is under 100 KB.

Will my photo look blurry at 100 KB?

Usually not. 100 KB is enough for a clear passport-size photo or a readable document page. The tool always picks the highest quality that fits.

Can I resize a PNG or WEBP to 100 KB?

Yes. PNG and WEBP files are accepted, and the result is saved as a JPEG, which is the format most forms ask for.

Are my photos uploaded anywhere?

No. Everything happens inside your browser, so your photos never leave your device.
