Compress passport photo to
100KB online.
Use the 100KB preset when your passport, visa, university, ID, or job portal allows a slightly larger photo but still rejects full-size camera images.
For smaller limits, use 50KB or 20KB. For Pakistan DGIP online passport uploads, see compress passport photo to 3MB.

FAQ
Passport photo questions
How do I compress a passport photo to 100KB?
Upload the photo, keep the 100KB preset selected, click Compress all, and download the compressed JPG.
Is 100KB better quality than 50KB?
Usually yes. A 100KB target keeps more face detail than very small targets like 20KB or 50KB.
Can I enter another KB value?
Yes. Type any custom KB value in the input if your form has a different limit.
Should I use JPG output?
For passport-style photos, JPG is usually the best format for small file sizes. Kodotools outputs compressed downloads as JPG.
Does it work on mobile?
Yes. You can upload from your phone gallery or camera and compress directly in the browser.
