WHY 20 KB?
When a 20KB image is useful
A 20KB limit is common on small identity photo fields and tightly restricted application portals. At this size, some reduction in dimensions may be necessary, especially for photos from modern phones.
01Exam and admission forms
02Government application portals
03Visa and ID photo fields
Quick tip Start with a tightly cropped photo. Removing unnecessary background gives the compressor more room to preserve the subject.

GOOD TO KNOW
Frequently asked questions
How do I compress a photo to 20KB?
Upload a JPG, PNG, or WebP image, keep 20 KB selected, then click Compress Image. Download the result once it is ready.
Will a 20KB image still look clear?
It depends on the original image and its dimensions. A 20KB limit is very small, so large photos may need to be reduced in resolution. Check your form's minimum pixel requirements before uploading.
Can I use a PNG for a 20KB limit?
Yes. If compression is needed, PixelsToKB converts it to JPG for a smaller result. Transparent parts are filled white.
