PDF Compressor

Try conservative PDF structure optimization with object streams. This limited browser tool does not recompress existing images and keeps the original if no smaller output passes checks.

Limited PDF structure optimization only. This does not recompress embedded images or guarantee savings. Complex PDFs with forms, links, annotations, signatures, attachments, or accessibility structure are rejected to avoid silently changing them. Files stay in your browser.

Maximum 8 MB and 60 pages. Uses PDF object streams; selectable page content streams are not rasterized. If output is larger, the original is retained.

How to use it

  1. Choose a simple PDF up to 8 MB and 60 pages.
  2. Optimize its document structure.
  3. Review the actual size and download the checked result or retained original.

Example & limitations

For example, a simple text PDF saved without object streams may become smaller after structural optimization.

Complex PDFs with forms, links, annotations, signatures, attachments, outlines, or accessibility structure are rejected. Page counts, dimensions, and stream bytes are checked; this is not a general-purpose compressor and may find no savings.
