Compress a PDF to 1 MB
Shrink large scanned or photo-heavy PDFs under 1 MB for portals and email, with no visible loss.
Why PDFs get so big
Phone-scanned documents store every page as a full-size photo, often 1–3 MB per page. Compressing those pictures to a sensible resolution usually brings a whole document under 1 MB.
Quality at 1 MB
For most documents the result looks the same as the original on screen and prints well. Only very long, photo-heavy PDFs need stronger compression.
Where 1 MB limits come from
University and job applications, insurance claims, and tax and court filings often cap each document at 1 MB. A PDF under 1 MB also opens quickly on a phone over slow mobile data, which helps whoever receives it.
Use cases
Longer documents
Theses, project reports and property papers with many scanned pages, for portals that cap uploads at 1 MB.
Court and tender submissions
E-filing and e-tender sites often set a 1 MB or 2 MB limit per file; compress large scanned bundles to fit.
Keeping photos readable
At 1 MB, photos inside a PDF stay clear, so it suits brochures and portfolios that still need to be light.
Questions
Can I compress a PDF to 1 MB on my phone?
Yes. Pick the PDF from your Files app, keep the preset and press Compress.
What if it's still over 1 MB?
The tool tells you the smallest size it reached. Split very long documents, or remove pages the form doesn't need.
Does it remove pages?
No. Every page stays; only the pictures inside are made smaller.
