About Compress PDF
Heavy PDF documents containing uncompressed photos and high-resolution scanned graphics frequently fail upload file limits on job portals, tax websites, and email attachments.
Our PDF Compression engine analyzes internal object streams, downsampling embedded heavy graphics while maintaining crisp vector fonts and document structure.
Because compression takes place entirely client-side, your confidential contracts, medical paperwork, and financial reports never leave your device.
