How this works — and why it's private
- Job portals, university applications and passport-renewal forms often cap uploads at 500 KB.
- It's the largest size that still attaches painlessly to any email service.
- For scanned documents, 500 KB usually keeps every stamp and signature readable.
- For text PDFs, 500 KB is essentially lossless — text stays perfectly selectable and printable.
