Frequently Asked Questions about 400KB

Answers to common questions about compressing to 400KB.

Why is my phone picture 4MB while portals only want 400KB?
Modern smartphones capture immense amounts of detail and high pixel counts meant for large canvas prints. Application portals only need enough detail for a standard screen view, hence the 400KB restriction.

Absolutely. 400KB is highly optimal for document scans, guaranteeing that all paragraphs, signatures, and fine print remain entirely legible.
