Compress PDF

Shrink large PDF files while keeping them readable and shareable — ideal for email attachments and upload limits.

About this tool

A PDF full of high-resolution scans or images can easily balloon past what an email attachment or upload form will accept. This tool shrinks the file by re-encoding embedded images and stripping unnecessary bloat, while leaving the actual text and layout untouched.

Pick a compression level that fits your priority: keep quality as close to original as possible, take the balanced default, or squeeze the file down as far as it'll go for the smallest possible size.
