Compress Image to 15KB Online — Free

Bring any image down to under 15KB in one click. A 15 kilobyte target sits between the signature-sized 10KB and the common 20KB passport limit, and shows up on a handful of registration and exam forms. The tool finds the best quality that still fits.

Required photo dimensions and file sizes differ between forms and change over time. This tool helps you hit a common target, but always verify the exact requirement on the official form or notification before you submit.

How to compress to 15kb

  1. Drop your image in, or click to browse and select it.
  2. The tool automatically finds the highest quality that still fits under 15KB.
  3. Check the live preview and the final file size.
  4. Download your optimised image — ready to upload.

FAQ

Frequently asked questions

Yes. PNGs are large because they are lossless, so the tool optimises and converts the result to JPG, which is the format almost every form expects for photos.

No. We never store, share or look at your images — every file is discarded the moment processing finishes and nothing is saved. That makes it safe even for sensitive documents like passports, ID cards and bank statements.

Yes. There is no cost, no watermark and no account needed. Anonymous users get a generous daily limit, which is plenty for everyday use.
