Compress PDF to 1 MB
Shrink a PDF to 1 MB — ideal for online portals with a 1 MB cap.
Compress PDF to exactly under 1 MB
1 MB is the sweet spot for most form uploads — tight enough to keep portals happy, roomy enough to preserve legible text and images. A typical colour scan straight off a phone is 4–10 MB; this tool walks JPEG quality and page resolution down in short iterations until the output is just under the 1 MB line.
Where 1 MB shows up
- Banking KYC uploads — Aadhaar, PAN, address proof
- Email attachments where the recipient caps incoming size
- Medical, insurance, and legal portals with a 1 MB cap
- Job application forms that accept resumes but reject large PDFs
- WhatsApp-based document workflows where smaller is always better
How 1 MB differs from smaller targets
Compared to Compress PDF to 500 KB or 100 KB, the 1 MB target lets the tool keep more image detail — scans stay clearly readable, colours don't posterise, and small text stays crisp. If your portal allows up to 1 MB, always pick this over tighter targets.

Frequently asked questions
Will formatting be lost?
No — page dimensions and layout are preserved exactly. Only image compression changes; the structure stays put.
Why does the output aim slightly under 1 MB?
Most portals treat 1,048,576 bytes as the hard cap. The tool stops at 990–1020 KB so there's no rounding surprise at upload.
Can I compress a 50 MB scan this small?
Usually yes — but expect visible quality loss. For massive scans, consider whether 2 MB is acceptable; you'll get a much sharper file.
Text-heavy PDF — will it stay readable?
At 1 MB, text in a 10–30 page scan remains clearly readable. Dense 50+ page documents may need a higher target to stay sharp.
Is my PDF uploaded?
No — all compression runs in your browser. The file never leaves your device.
