Compress PDF to 100 KB
This page opens the PDF compressor with the size already set to 100 KB. Choose your PDF, press the button, and you get a copy that is 100 KB or smaller, ready to upload. Many government, exam and job forms in India accept documents only under 100 KB, such as marksheets, caste or income certificates and address proofs.
How it gets the size down
Each page is redrawn as a lighter picture, step by step, until the file fits under 100 KB. The tool tries several levels and keeps the clearest one that fits. If your PDF is already under 100 KB, it is returned unchanged.
When the size cannot be reached
Some files have many pages or very detailed scans. If 100 KB would make the pages unreadable, the tool stops and tells you the smallest size it managed, instead of giving you a blurred file. Then split the PDF into parts, remove pages you do not need, or ask whether a slightly larger file is allowed.
Good to know
Because pages become pictures, text in the compressed PDF cannot be selected, and links and form fields are removed. Keep your original file. Everything happens in your browser, so private documents are never uploaded.
