How it works
- Add your PDF. This page starts with the 2 MB target selected.
- The tool tries 150 DPI first, then lower resolutions down to 48 DPI, and stops as soon as the file is under the target.
- If the target cannot be reached, you get the smallest result with a note. If even that is larger than your original, the tool says so and gives no file.
When this size fits
- This is the gentlest size on the list, so pages stay sharp longer than at smaller targets.
- If the file is already under 2 MB, nothing is changed and no new file is made.
- Large photo-based PDFs gain the most. Text-only PDFs can come out larger, and the tool says so.
What a test showed
- One-page A4 scan, 474 KB: already under 2 MB, so no new file was made.
- Ten-page A4 scan, 4.7 MB: the result was 1.7 MB.
- At this target the tool usually stays at a higher resolution than for the smaller sizes.
Test numbers come from synthetic files made for this page: a one-page A4 scan (474 KB) and a ten-page A4 scan (4.7 MB), both noisy 150 DPI images. Real files behave differently, so treat them as a guide.
Limits
- Pages become JPEG images: selectable text, links, forms and signatures are lost.
- Sizes use 1 KB = 1,000 bytes. Up to 30 MiB and 100 pages per file.
