Why Compress PDFs with PDFLOL?
PDF documents containing high-resolution scans, embedded graphics, and vector diagrams can quickly reach sizes of 20MB, 50MB, or more. Large PDF files cannot easily be attached to emails (which typically enforce a 25MB attachment limit) or submitted to government and job portal application forms.
With PDFLOL PDF Compressor, object streams and unneeded internal metadata are reorganized efficiently right in your browser using modern WebAssembly and PDF-Lib. Because computation occurs 100% locally on your machine, your confidential files never leave your computer.
