What is PDF Compress?
This is a 'light' compressor — it removes redundant PDF structure without altering content. Expect savings of 10-40% on PDFs from word processors. For image-heavy PDFs, a dedicated rasterizer-based compressor will save more.
FAQ
- Will my PDF quality drop?
- No — this is lossless. Same pixels, smaller file.
- Is my PDF uploaded anywhere for compression?
- No. Compression runs entirely in your browser. Your document stays on your device and is never sent to any server.
- Is this tool completely free to use?
- Yes — 100% free, no sign-up, no watermarks, no hidden limits. Just open the page and compress.
