Compress PDF

A tool to compress PDF files shrinks file size by optimizing images, removing redundant data, and cleaning out hidden metadata without noticeably degrading the visual quality of your document. A 20 MB PDF does not need to stay 20 MB when you can reduce PDF file size significantly with just a few clicks.

Email attachment limits, website upload caps, and cloud storage quotas all care about file size. Compressing a PDF from 15 MB to 3 MB can be the difference between an email going through or bouncing back. Real estate agents compress property PDFs for faster client sharing.

Three compression levels give you control over the trade-off between quality and size. Low compression maintains the best quality with moderate size reduction. Medium compression balances quality with file size, typically reducing documents by fifty to eighty percent with no visible difference.

High compression produces the smallest files possible, ideal for archival storage where size matters more than absolute image fidelity. Documents with large images see the most dramatic size reductions at this level.

Image optimization is the primary driver of file size reduction. Images inside the PDF are recompressed using efficient algorithms that maintain visual quality while significantly reducing the data footprint. Photographs and complex graphics benefit most from optimization.

Metadata stripping removes redundant information like document properties, edit history, and embedded thumbnails that are not essential for viewing. This contributes additional savings on top of image optimization, especially for documents with extensive editing history.

Unused fonts embedded in the PDF are identified and removed. Many PDFs include font subsets for characters that are never used in the document. Cleaning these out reduces file size without affecting the visual appearance of any text. This PDF compressor handles all these optimizations automatically.

For most documents, medium compression reduces size by 50-80% with no visible quality difference. The compressed file is suitable for email, web upload, and general distribution. Always preview the compressed output before deleting the original.
