Frequently asked questions
How do I compress a PDF to under 100 KB?
Upload the PDF, choose the 100 KB target and compress. The tool shrinks the photos and scans inside the PDF first and keeps the text selectable where it can.
Why is 100 KB hard for a scanned PDF?
A multi-page scan is mostly large images. To reach 100 KB, a PDF may need lower image quality or a lower page count, so scan at a moderate resolution if you can.
What if the file cannot get below 100 KB?
If the size can’t be reached by compressing images, pages may be converted to images, and you are told when that happens. You can also remove pages you don’t need first.
Is it safe for ID documents?
Yes. Everything runs in your browser, so your documents are never uploaded.
