Free PDF Compressor Online

Toolton's free PDF compressor helps reduce PDF file size directly in your browser. No account or software installation is required.

A smaller PDF can be easier to upload, share, store and send when a website or application has a file-size limit.

Compress PDF to a Smaller File Size

Select a target size such as 20KB, 50KB, 100KB, 200KB, 500KB or 1MB. The selected size is treated as a target rather than a guaranteed output size, because already-optimized PDFs may not be reducible to every target.
