We tested it: three PDFs compressed to 1 MB
Tested on October 28, 2026 with a CV with a photo (3 pages, 1.3 MB), a phone scan of a certificate (4 pages, 1.3 MB) and a brochure full of photos (6 pages, 3.6 MB). ppi: pixels per inch of the redrawn pages.
| After | ppi | How it reads | |
|---|---|---|---|
| CV, 3 pages | 678 KB | 150 | Sharp, small print too |
| Scan, 4 pages | 751 KB | 150 | Sharp, small print too |
| Brochure, 6 pages | 893 KB | 150 | Sharp, small print too |
At 1 MB the 4-page scan reads as “sharp, small print too” at 150 ppi. In Black and white it came out at 743 KB instead of 751 KB, at the same 150 ppi, so keeping colour costs almost nothing.
Almost any document fits under 1 MB with little or no visible change, including scanned contracts and photo-heavy reports. How the PDF compressor works.
How many pages fit in 1 MB?
| Pages | 1 MB |
|---|---|
| Typed pages (no photos) | 50+ |
| Scanned pages, still clear | 25+ |
A 1 MB limit shows up on e-filing and tax portals, company and GST registration uploads (where proof documents are usually limited to 1 MB each), and on websites that cap email attachments. It is enough for nearly any document, including long scans. See the official limits for SSC, IBPS, SBI, NEET, JEE and GATE.
Tips for a clear, small PDF
- Most PDFs get there losslessly, so text stays selectable and nothing changes in how it looks.
- Big brochures and slides are mostly images; they compress well without looking different on screen.
- Very long scans (50+ pages) may need splitting into parts.
