Can every PDF be compressed to 500 KB?

Most text documents and scans of a few pages can. Very long documents or pages full of detailed photos may not fit under 500 KB while staying readable; in that case you get the smallest readable version and a note that the target was not reached.

Will my text still be selectable?

If the file reaches the target with structural optimization alone, text, links, and forms are kept. If pages have to be re-encoded as images to get smaller, the text is no longer selectable. The result message tells you which happened.

How to compress a PDF?

Open Compress PDF, choose your PDF, select the compression level, then download the optimized PDF. Compression results vary with the images, fonts, and structure in the original document.

Compress PDF to 500 KB

Reduce a PDF to 500 KB or less for web uploads and lightweight sharing, privately in your browser.

Compress PDF to 500 KB shrinks a document until it fits under 500 KB, a common limit for web uploads and lightweight sharing. Choose your file and the tool first tries lossless optimization, then re-encodes pages at the highest quality that still fits. Everything runs in your browser, so the PDF is never uploaded.
