Questions people ask
How do I reduce a photo to 50KB?
Choose your photo above, tap 50KB, and press “Make it 50KB”. The tool keeps the best quality that still fits under 50KB and downloads a JPG.
Is my photo uploaded anywhere?
No. The photo is resized inside your own browser. It never leaves your phone or computer.
The form also asks for size in pixels (like 200 × 230). Can I do that?
Yes. Turn on “Also set exact size in pixels”, type the width and height, and the photo is cropped neatly from the centre to fit.
Can I use this for a signature?
Yes. Most forms want a signature between 10KB and 20KB. Choose “Custom” and type the number you need.
