About Compress to exact KB

Portals, forms and exam sites set hard limits like 20 KB for a signature or 50 KB for a photo. Type the limit and the tool finds the highest quality, and if needed the smallest resize, that lands under it. Every download is guaranteed to fit.

  • Common targets: 10 to 20 KB for signatures, 20 to 50 KB for passport photos, 100 to 200 KB for documents.
  • Very small targets may scale the image down; the tool keeps it as large as the budget allows.
  • For a specific portal, Exam portal presets applies the exact pixel and KB rules.

How to use it

  1. 1Drop one or more images.
  2. 2Type the target size in KB.
  3. 3Download; each file is under the limit.

Questions

How does it hit the size exactly?
It tries a series of quality levels, then dimensions, and keeps the best result that fits under your target.
Will a 20 KB photo look bad?
For a passport-style photo at 200 by 230 pixels, 20 KB is plenty and looks clear. Large scenes will show more compression.
Is my photo uploaded?
No. Everything runs in your browser, so your photos never leave your device.
