PDF Compressor
Reduce scanned PDF size with JPEG downsampling. Choose resolution and quality; keep the original when it is already smaller.
Your input is sent to this site only after you choose Convert on server. The conversion runs for this request and no history is saved. Upload up to 4 MiB combined; Office files have a 2 MiB limit.
Before you convert: Rebuilt pages become images: selectable text, forms, links and signatures are not preserved. Maximum 20 pages. If the original is smaller, it is returned unchanged by default.

Make an image-heavy PDF easier to send
Scanned documents and photo-heavy PDFs often contain more image detail than a recipient needs for on-screen reading. This compressor renders each page at your chosen resolution and stores it as a compressed JPEG inside a new PDF. Lower resolution and quality can reduce size, but also make small writing harder to read. Inspect the downloaded result before using it for an application or sharing important records.
Understand the raster conversion
The rebuilt PDF contains page images rather than selectable text, live form fields or vector artwork. Original links, annotations and signatures are not carried into that rebuilt output. The operation supports up to twenty pages and cannot promise a specific final size. By default the original is returned unchanged when rebuilding would increase its size; its download name identifies that case. This method is most appropriate for scans, not text-preserving optimization.
Where is my file processed?
The selected file is sent to this site only when you run the server conversion. Processing uses memory without a saved conversion history.
Is input uploaded?
This tool sends input to this site’s conversion API after you select Convert on server. Files use bounded workers and, when needed, private temporary folders deleted after processing or cancellation. No conversion history is saved. The converter does not upload files to a third-party conversion service.
