How to Compress a Scanned PDF for a Government Website
Government and exam portals often reject scanned PDFs that sit above a hard size cap — 200KB, 500KB, 1MB, or 2MB. Scans are image-heavy, so the file looks fine on your phone but fails on the website.
You do not need Adobe. Upload once, pick a stronger level for scans, check the download size, then submit.
Why scanned PDFs fail portal uploads
A phone scan stores each page as a large image. Even a two-page form can exceed a portal limit. Text-only PDFs rarely have this problem; photo-style scans almost always do.
The fix is to reduce image weight inside the PDF — not to argue with the portal.
Step-by-step: shrink a scanned PDF for upload
Open Compress PDF, upload the scan, and start with Extreme if the portal limit is tight. Recommended works when you only need a modest shrink.
- Upload the scanned PDF on Compress PDF.
- Choose Extreme for government or exam size caps; use Recommended if quality matters more.
- Download the smaller file and check its size in Files or File Explorer.
- If it is still over the limit, crop blank margins in your scanner app, or split into fewer pages first.
Keep the form readable
Strong compression can soften fine print. Zoom the download and confirm signatures, stamps, and ID numbers are still clear. If not, switch to Recommended and remove unused pages instead of crushing quality further.
FAQ
What size should I target?+
Use the portal’s stated limit. If it says 1MB, aim under 900KB so the upload has headroom.
Will Extreme ruin my scan?+
It can soften fine print. Always zoom a stamped page before you submit. Fall back to Recommended if numbers blur.
Can I compress on my phone?+
Yes. The same Compress PDF page works in mobile Safari and Chrome.
