About Compress PDF

Compress PDF reduces a document’s file size so it fits under email attachment limits and loads faster on the web. Two levels are offered: Web, which downsamples images for the smallest file, and Print, which keeps images sharper for higher-quality output. After compressing, the tool shows the original size, the new size and the percentage saved.

You can compress up to 10 PDFs in one batch — multiple results are bundled into a single ZIP download. Savings depend on the document: image-heavy PDFs shrink dramatically, while already-optimized, text-only files may barely change, and the tool tells you when that happens.

Compression runs on the server with a deterministic optimizer. Files are processed privately and cleaned up automatically, and the download starts as soon as the result is ready.

How to use Compress PDF

  1. Drag and drop the PDF — or up to 10 PDFs at once.
  2. Choose the compression level: Web for the smallest size, Print for higher quality.
  3. Click “Compress PDF”.
  4. Check the before/after sizes and percentage saved, then download the result — multiple files arrive as one ZIP.

Yes, up to 10 in one batch. When you compress more than one file, the results are bundled into a single ZIP archive for download.

No. Text stays crisp because compression mainly targets embedded images. At the Web level, photos are downsampled but remain perfectly readable on screen.
