What fits in 100 KB
A scanned A4 page stays readable at roughly 50 to 100 KB, so this size suits one page, sometimes two. Five pages would leave about 20 KB each, and small print gets hard to read.
If your scanner app offers grayscale or black and white, use it. Those scans are usually smaller, which leaves more room for sharp text.
How to compress a PDF to 100 KB
- Choose your PDF. Target size is already set to 100.
- Press Compress. It tries several quality levels on the pictures and keeps the best one that fits.
- The file downloads. Open it and check that scanned pages are still easy to read.
FAQ
Why can't my PDF reach 100 KB?
Only pictures shrink here. Text and fonts are kept exactly as they are so the words stay selectable, and they can take more than 100 KB on their own. The tool tells you the smallest size it reached.
What if a multi-page PDF will not fit?
Use Split PDF to keep only the pages the form asks for, or upload the pages separately if the form allows it.
Is my PDF uploaded?
No. Compression runs in this tab.
Will it work on a password-protected PDF?
No. Remove the password in the program that made the file, then try again.
