Before you submit
- 1 MB is roughly the size of one uncompressed phone photo, so a multi-page scan straight from a phone app is often 5–20 MB.
- If a 1 MB PDF still bounces from email, the limit is on total attachment size. Send fewer files, or link to it instead.
- For government portals that ask for 1 MB, check whether the limit is per file or for the whole application.

It varies, so the tool aims about 3% under the upper limit and, where there is a lower limit, just above it in 1,024-byte KB. The file is accepted either way.
