A 100 KB limit is one of the strictest you will meet. It shows up on older government and recruitment portals, on some university systems and on forms where many small files are uploaded together. These sites keep the limit low so their servers stay fast.
This page opens Compress PDF already set to the Smaller mode with a target of under 100 KB. You only need to add your file and press Compress PDF.
A 100 KB file has room for very little. It works well for one-page documents and gets hard after two or three pages.
For a long transcript or a report, check if the portal lets you upload each page as a separate file. One page under 100 KB is much easier than ten.
A phone scan saves every page as a large, detailed photo. That is why a one-page scan can easily be 2 or 3 MB. In the Smaller mode each page is redrawn as a lighter picture.
The tool aims a little below 100 KB on purpose. Some sites count 100 KB as 100,000 bytes and others as 102,400, so staying just under 100,000 passes both.
In the Smaller mode the text becomes part of the picture. It looks the same, but you can no longer select or search it. If your PDF already fits without that change, the tool keeps the text as it is and tells you.
Sometimes a file has too many pages or too much detail. The tool then gives you the smallest version it could make and shows its size, so you know how close it came.
Then run the smaller file through this page again.
Strict portals often reject a file without saying why, or only after you have filled in the whole form. Open the compressed PDF once before uploading it. Zoom in on the parts the office will read: your name, father's name, roll number, CNIC number, dates and any stamp. If something important is hard to read, the page needs more room than 100 KB gives it. In that case, cut the document down to the one page the form really asks for and compress again. Also look at the file size shown after compressing. It is counted the way forms count it, so if it says under 100 KB here, the portal should see the same.
Add your PDF on this page and press Compress PDF. The Smaller mode and the under 100 KB target are already chosen. Download the result when it shows the new size.
For one or two pages, usually yes. The tool keeps the highest quality that fits. With many pages, each page gets less room, so the text can look softer.
Phone cameras and scanners save each page as a detailed colour photo. That can be several megabytes even for one sheet of paper.
No. The compression runs inside your browser, so the PDF stays on your device.
Not directly. Unlock it first, then compress it.
Choose Under another size in the Size box and type 150. The tool works the same way for any size.
