Frequently Asked Questions

Why do government portals demand minimum image sizes?

Many portal checkers have minimum byte validation (e.g. 100KB–200KB) to prevent excessively compressed or blurry thumbnail files from being submitted.

Does increasing KB degrade image quality?

No. Unlike compression, increasing size preserves 100% of the existing visual clarity and safely expands the byte structure to pass portal validation.

Can I increase a 15 KB signature to 100 KB?

Yes. Upload the 15 KB signature, pick 100 KB, and click "Increase Image Size".

What format will the downloaded image be in?

The downloaded image will always be a standard compliant JPEG (.jpg) file.
