PDF Compress

PDF Compress reduces the file size of your PDF documents by stripping unnecessary metadata, removing duplicate resources, and optimizing the internal document structure. This is ideal for making large PDFs small enough to email, upload to file-sharing platforms, or store more efficiently. The tool works entirely in your browser, so your documents remain private.

PDF files often contain hidden bloat - embedded font subsets that are duplicated, metadata from the authoring software, unused resources, and inefficient internal references. This tool reads the PDF, rebuilds its structure cleanly, and removes the excess. The visible content of your document stays exactly the same while the file size can be reduced significantly depending on how much bloat was in the original.

The compression is lossless in terms of visible content - text and vector graphics remain at full quality. Image-heavy PDFs may see smaller reductions since image data typically makes up the bulk of the file size. For maximum compression of image-heavy documents, consider reducing the image quality in the source before generating the PDF.
