Compress PDF and Reduce File Size

How do I reduce the size of a PDF file?

Upload the document and choose a compression level. The stronger the compression, the smaller the file may be — but image quality may drop, so review the result.

How it works

  1. Upload a PDF.
  2. Choose a compression level.
  3. Run the processing.
  4. Check and download the result.

Compression is useful before sending by email, uploading to a system with a size limit, or archiving. Text-heavy documents usually stay readable even after moderate reduction.

There is no fixed compression ratio for every file. The result depends on the number of images, resolution, fonts and the PDF internal structure.

Frequently asked questions

Does quality suffer?

Compression may reduce image quality. Start with a moderate level and review the result.

How small will the file be?

Savings vary by document structure; no final size can be guaranteed in advance.

Will the text stay readable?

In most files the text stays readable, but you should always review the generated file.
