Where you need a photo under 10KB

  • Signature uploads that ask for 10KB–20KB
  • Thumb impression uploads
  • Small ID photos on older portals

For a signature: sign with a black pen on plain white paper, take a photo in good light, and crop close around the signature. If the form also gives pixel size (like 140 × 60), turn on “Also set exact size in pixels”.

Questions people ask

How do I make my signature 10KB?

Take a clear photo of your signature, choose it above, and press “Make it 10KB”. Crop close to the signature first for the best result.

The form says between 10KB and 20KB. What should I pick?

Choose “Custom” and type 19. Our result stays under the number you type, so a little below the maximum is safest. If a form also has a minimum, check the new size we show.

Is my signature safe?

Yes. It is resized inside your own browser and never uploaded.

Is my photo uploaded anywhere?

No. The photo is resized inside your own browser. It never leaves your phone or computer.
