Compress PDF to 500 KB
This page opens the PDF compressor with the size already set to 500 KB. Choose your PDF, press the button, and you get a copy that is 500 KB or smaller, ready to upload. A 500 KB limit is common for longer documents, resumes with photos and scanned applications.
How it gets the size down
Each page is redrawn as a lighter picture, step by step, until the file fits under 500 KB. The tool tries several levels and keeps the clearest one that fits. If your PDF is already under 500 KB, it is returned unchanged.
When the size cannot be reached
Some files have many pages or very detailed scans. If 500 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.
