How to compress a PDF to 500 KB
A 500 KB target is ideal when you want a small file without giving up visible quality: photos that still look good, scans that stay readable, and a file that emails without trouble. It is also a common default target size, because it sits comfortably below most upload limits.
Drop your PDF, choose 500 KB, and press Compress. The tool re-encodes the images inside until the file reaches 500 KB. Vector text is never touched; only photos and scans are compressed. A multi-page document with photos can drop from 20 MB to 500 KB without the difference being visible to the naked eye. Everything runs in your browser, so your document never goes to a server. If your form demands less than 500 KB, try 200 KB; if you want the best quality possible, use 1 MB.
