Frequently asked questions

Why do portals ask for images under 20KB?

High-volume systems cap file sizes to keep storage and processing manageable. 20KB comfortably holds a clear passport-style JPEG, which is all the portal needs.

Will compressing to 20KB make my image blurry?

Not with exact-size compression. The tool stops at the highest quality that fits — it never compresses more than the cap requires. Very detailed full-scene photos lose more than portraits; for forms, a portrait crop compresses best.

Does this work for PNG and iPhone HEIC files?

Yes — PNG transparency flattens to a white background and HEIC converts to JPEG automatically, since portals only accept JPEG.

I need 50KB or 100KB instead — can I do that here?

This page is tuned for the 20KB cap. For any other limit, use the custom KB target on our Exam Photo & Signature Resizer.
