Compress PDF
Reduces the file size of PDF documents through smart compression.
What Compress PDF does
Compress PDF is an online service that reduces the file size of Portable Document Format documents through image optimization and structural streamlining. Users upload a PDF and choose between two compression modes: "Maximum" for the smallest possible file or "Recommended" for a balance between compactness and visual quality. The processed file preserves readable text and decent image quality, making reports, presentations, and scanned papers suitable for sharing. The service emphasizes privacy, noting that uploaded files are not shared with third parties and are automatically erased within two hours, with an option for earlier manual deletion. Beyond compression, the platform hosts over 90 additional PDF tools for editing, splitting, merging, and more. Compress PDF distinguishes itself through its dual-mode approach and broad language support. While other compressors offer single settings, this tool lets users explicitly trade off size versus quality with a clear "Maximum" versus "Recommended" toggle. The interface is multilingual, supporting over a dozen languages, and the site integrates the compressor within a larger suite of 90+ PDF utilities. Privacy protections—automatic file deletion and no third-party sharing—are explicitly highlighted, and the service claims compatibility across phones, tablets, and desktops without requiring software installation.
