Resize photo in KB: common questions

Which size should I choose?

Every form sets its own limits, and they change between years. Check the photo or signature size printed in your form’s instructions, then type those numbers here. The sizes on this page are common starting points, not any exam’s official rule. For JEE Main, NEET, CUET, CTET and IBPS, the exam pages use each notice’s own numbers.

Is there a limit on how many photos I can resize?

No. There is no daily or monthly limit and no account, and it stays free for life: use it as often as you like. It all happens on your device, so ScalePDF sets no size limit.

My form says “between 10 KB and 20 KB”. Can it do that?

Yes. Set the minimum to 10 and the maximum to 20. ScalePDF keeps as much quality as fits under the maximum. If even the best quality is smaller than the minimum, the file is padded with blank data to reach it; the picture itself is not changed.

Crop or fit?

“Crop to fill” fills the whole size and trims the edges of the photo, best for passport-style photos. “Fit whole photo” keeps all of it and adds white bars.

Is my photo uploaded?

No. The photo is resized right here in your browser or the app and never leaves your device. Nothing is uploaded, stored or shared.
