PDF Optimizer — Reduce PDF Size Without Rasterizing

PDF Optimizer — Reduce PDF Size Without Rasterizing. Optimize PDF structure locally without rasterizing pages. Optional clearing of six document properties; keep the exact original when there is no size saving. Up to 20 MiB and 100 pages.

Optimize PDF structure locally without turning pages into images. Choose one PDF up to 20 MiB and 100 pages. Password-protected files are unsupported, and each run stops after 60 seconds.

How to optimize a PDF Choose a PDF and decide whether to clear six document properties. Select Optimize PDF. Cancel, change the file or clear it to stop processing. Compare original and download sizes, then download and review the result. What changes?

The tool writes compressed object streams without downsampling images. The optional property setting clears title, author, subject, keywords, creator and producer. Dates, XMP and other hidden data may remain. This is not a privacy scrubber.

Re-saving invalidates digital signatures and does not certify PDF/A compliance. What if there is no saving? The tool keeps the exact original bytes, metadata and filename when the candidate is not smaller.

Processing and storage The tool reads your PDF on this device without uploading it or saving it in browser storage. Ads make separate network requests. Clear the file or leave the page to release its result. Optimizer or Compressor?

Try Optimizer for structural savings while retaining selectable text. For scanned PDFs, PDF Compressor can save more by turning pages into images, losing selectable text and interactive links and forms. Always review the output before replacing your original.

Frequently asked questions

How do I optimize a PDF?

Choose one PDF up to 20 MiB and 100 pages, set the optional property clearing, then select Optimize PDF. Compare sizes and download. Cancel stops a pending run; each run is limited to 60 seconds.

What does PDF Optimizer change?

It re-saves the document with compressed object streams without rasterizing pages or downsampling images. Review text, links, forms and page appearance before replacing your original. Re-saving invalidates digital signatures; PDF/A compliance is not certified.

How much smaller will my PDF get?

Savings depend on the internal structure and may be small or zero. If the candidate is not smaller, the download keeps your exact original bytes, metadata and filename.

Does this remove all metadata?

No. When selected, it clears title, author, subject, keywords, creator and producer in the smaller output. Dates, XMP and other hidden data remain. Uncheck the option to keep those properties. No-saving downloads retain all original metadata.

Why cannot my PDF be optimized?

Damaged, encrypted or password-protected PDFs are unsupported. Files must be non-empty, at most 20 MiB and contain 1–100 pages. Complex documents may exceed the 60-second limit.

Is my PDF uploaded or stored?

The tool reads your file locally without uploading it or saving it in browser storage. Ads make separate network requests. Clear the file or leave this page to release the result.
