Compress PDF to 100 KB
Admission, scholarship, exam and government portals hard-reject PDFs over 100 KB with a generic error and no hint why. This tool opens pre-set to a 100 KB limit and keeps re-rendering your pages at lower quality until the file fits — then tells you honestly if it cannot.
Get under a size limit
Picking a size limit automatically turns pages into compact images and dials quality down until the file fits. Nothing is ever uploaded — compression happens entirely in this tab.
Getting under 100 KB without regretting it
Scans are the usual culprit
One phone-camera photo of a page can be 1.5 MB. A 100 KB cap really means “text pages only”, so expect the tool to re-render pages as compact images.
Readability at 100 KB
A plain text page lands around 15–30 KB this way — perfectly readable on screen and in printouts. Photo-heavy pages will soften.
If it still won’t fit
Split the PDF and upload only the pages the form asks for, or drop the embedded scans and re-type those pages as text.
Good to know
Will a 100 KB PDF still be readable?
Yes for text documents. Pages are re-rendered at roughly screen resolution — body text stays crisp, only very fine print softens.
What if the tool can’t get under 100 KB?
It will show the smallest honest result and say so. Then split the file or replace scanned pages — padding the file down with worse tricks usually breaks the portal’s PDF parser.
Does it work for scanned documents?
Yes, but a 100 KB cap on a scan means heavy downscaling. If a page becomes hard to read, remove it from the upload or contact the portal for a higher limit.
