YOUR WORKSPACE

PDF Compressor

Keep your original. Do not process digitally signed or password-protected PDFs. Compression can invalidate signatures or affect forms, annotations and accessibility. Check every page of the output.

One PDF, up to 20 MB and 30 pages.

The original file will not be changed.

Choose a method

Repackages the PDF without intentionally rasterizing pages. Text is normally still selectable. Savings are often small or zero; interactive features and signatures are not guaranteed.

Renders each page as an image. Text selection, accessibility, links, forms, annotations and signatures are not preserved. Image quality and readability can decrease.

1 KB = 1,000 bytes. This is a check, not a guarantee.

HOW IT WORKS

Compress with care.

  1. Select a PDF and keep a backup of the original.
  2. Choose a method and, optionally, enter the maximum size your application permits.
  3. Compare the first page, download the result and inspect every page.
Example: compare sizes

CHECKED RESULT

For demonstration purposes only. This illustration is not an official requirement.

Will the file always get smaller?

No. Some PDFs are already optimized. A result can be the same size or larger. The tool reports the actual result; adjust your settings or keep the original.

Can it always reach my target KB?

No. The target checks the output size. It does not guarantee that size or automatically adjust quality. Very small targets can make pages unreadable.

What happens to text in image-based mode?

It becomes part of a page image, so it is no longer selectable or searchable. Links, forms, annotations and accessibility information may be lost.
