1 MB is roughly 1,000 KB to spread over the pages. In our tests three colour pages kept 169 dpi, six pages about 98 dpi and ten pages about 103 dpi at JPG quality 50. India's customs procedure gives a matching rule of thumb: at 75 KB per black-and-white page, “the maximum permissible file-size is 1 MB … would allow the submitter to upload a supporting document which is up to 13 pages long” (e-SANCHIT procedure).
| Pages | Test file | Result | Resolution reached | Readability |
|---|---|---|---|---|
| 1 | ID-style scan, 1.0 MB | 851 KB | 200 dpi · q80 | sharp, prints well |
| 2 | photo pages, 1.4 MB | 812 KB | 200 dpi · q72 | sharp, prints well |
| 3 | colour text scan, 2.5 MB | 969 KB | 169 dpi · q72 | sharp, prints well |
| 6 | grey text scan, 6.1 MB | 883 KB | 98 dpi · q80 | normal text readable |
| 10 | mixed scan, 5.0 MB | 968 KB | 103 dpi · q50 | clear on screen |
Measured on 16 October 2026 with this tool in browser mode on our own test PDFs (synthetic A4 scans with paper noise, which is harder to compress than a clean office scan). Your numbers will differ; cleaner scans get higher resolution. “q” is the JPG quality the tool settled on. Readability labels are a rough guide: 100 dpi and up is clear on screen, 70–100 dpi keeps normal-size text readable, below 50 dpi only large text survives.
We aim for under 1,000,000 bytes, so the file passes portals that count either way.
About 13 black-and-white pages at the e-SANCHIT standard, or 6–10 mixed scans at around 100 dpi in our tests.
Probably not — rasterising text makes it bigger per page. Use high-quality compression, which keeps the text.
Not in browser mode, which is the default. Server mode sends the file to our server, processes it in memory and does not keep it.
