Can every PDF fit under 100KB?
One or two scanned pages usually fit easily. Long PDFs with many pages may not fit while staying readable. Remove extra pages with Delete PDF Pages first.
Will my marksheet still be readable?
The tool stops at the first setting that fits, so it keeps as much detail as possible. Zoom in on the result before you upload it.

Questions people ask
Is compressing a PDF to 100KB free?
Yes, free and unlimited.
Why is my PDF still above 100KB?
If it has many pages, even the smallest readable setting can be too large. Split it or delete pages, then try again.
Is my PDF uploaded?
No. Everything happens on your device.
How much smaller will my PDF get?
Scanned PDFs and PDFs full of photos often shrink by 50 to 90 percent. PDFs that are mostly typed text are already small, so they shrink less.
Will the text stay sharp?
Recommended keeps text easy to read on screen and in print. Extreme makes the file much smaller, but fine print can get soft, so check it before you upload.
