Compress PDF to 1 MB
This page opens the PDF compressor with the size already set to 1 MB. Choose your PDF, press the button, and you get a copy that is 1 MB or smaller, ready to upload. A 1 MB limit is common on email-based applications, university portals and bank uploads; most documents of a few pages reach it easily.
How it gets the size down
Each page is redrawn as a lighter picture, step by step, until the file fits under 1 MB. The tool tries several levels and keeps the clearest one that fits. If your PDF is already under 1 MB, it is returned unchanged.
When the size cannot be reached
Some files have many pages or very detailed scans. If 1 MB 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.
