About this output

Repackages the entire PDF without rendering pages or flattening forms. Existing text, vectors and document objects remain; images are not recompressed. If the result is not smaller, you receive the unchanged original. Savings are not guaranteed. Encrypted, signed and XFA documents are unsupported. Review the saved copy in your PDF viewer.

How to use
  1. Choose your PDF or try the built-in synthetic sample. Keep the original file.
  2. Choose structural optimization first. Use image compression only when losing selectable text is acceptable, then inspect the output.
  3. Try structural optimization first and check text selection, forms and links in the saved file. No reduction is promised; a result that is not smaller returns the original. Image compression is a separate lossy mode.
  4. Download the result and reopen it in your own PDF viewer before sharing.

Example: Structural optimization may save space without rasterizing; 96 DPI and 65% quality are separate lossy settings for scanned reports.

Limits and help

Structural optimization repacks all pages without rasterizing; it does not recompress images and returns the original if no reduction is achieved. Encrypted, signed and XFA files are unsupported. The separate image-compression mode removes selectable text, links, forms, bookmarks and accessibility structure; fine details may blur. Image mode supports at most 60 selected pages. No mode guarantees a smaller file.

Your files are yours.

Image and text processing happens in your browser. Your files are not uploaded to our servers.

Troubleshooting

Encrypted or damaged documents may not open; use an unencrypted copy only when you are authorized to access it. A scan without a text layer will not yield text with ordinary extraction. At a processing limit, reduce the file or page range and keep the original.
