Reduce the size of a PDF document
Compress a PDF for sharing, storage, or publishing. The original file stays on your device.
Choose a structure-preserving profile or compare it with reduced JPEG pages for stronger scan compression. The tool keeps the smaller result and reports whether text and links remain available. Processing is local and the PDF is never uploaded.
Choose a PDF and compression settings
Standard compression keeps selectable text and document structure. Maximum compares it with a reduced scan rendered as JPEG pages and keeps the smaller result.
No PDF selected.
This profile keeps PDF text and structure. Images already compressed as JPEG are not re-encoded.
Maximum mode keeps the image-page version only when it is smaller. In that result, text cannot be searched or copied, and links, forms, and signatures are not preserved.
Files stay on this device. Choose a PDF to begin.

Compress a PDF without uploading it to a server
PDF compression can reduce a document before you email it, publish it online, or store it in the cloud. The tool shows the original and resulting file sizes so you can review the outcome before downloading.
- Balanced profile: keeps text readable and optimizes supported images.
- Maximum compression: compares a standard PDF rebuild with reduced JPEG pages and chooses the smaller file. In the image-page version, text, links, forms, and signatures are not preserved.
- Strong compression while keeping text: keeps the PDF structure, but images already compressed as JPEG are not re-encoded.
- Lossless image quality: rebuilds the PDF structure without re-encoding images.
- Full mode lets you set JPEG quality, maximum-mode resolution, stream compression, and the source document password.
- Standard compression keeps text and page order. A digital signature may become invalid after a PDF is changed.
- Files up to 100 MB are processed on your device and are not sent to a server.
Compression cannot reduce every PDF: an already-compressed or mostly text-based document may stay the same size or grow slightly. The original is never replaced, and the result remains available to download.
