Compress PDF to 500KB

1. Upload your PDF (up to 50 MB).
2. The compressor automatically targets 500 KB or under.
3. Download the compressed PDF.

500 KB is generous — most PDFs fit easily with minimal compression. Perfect for high-quality documents on forms and email attachments.

500 KB is the target for portals and forms that need compact PDFs but also want high-quality content. Most documents fit easily with minimal compression, preserving sharp text and high-quality images.

The compressor analyzes the PDF and iterates image quality until the output is 500 KB or under. Text is preserved losslessly; images retain good resolution.
