How Many Pages Fit in 400 KB?
The size limit applies to the whole PDF, so more pages means less room for each one. The table shows the rough space per page when you stay under 400 KB.
| Pages | Space per page |
|---|---|
| 1 | 400 KB |
| 2 | 200 KB |
| 3 | 133 KB |
| 5 | 80 KB |
Documents on white paper compress far better than colour photographs, so scan or photograph them flat and in good light.
Tips for Best Results
- Photograph documents flat, in daylight, with the page filling the frame.
- Crop away table and background before you convert.
- For a size limit, black-and-white or high-contrast scans end up much lighter.
Limits and Things to Know
- Pictures are embedded as JPG pictures, so text inside them cannot be selected or searched.
- Transparent PNG areas become white.
- Many pages with a small limit lowers each page's quality a lot.
