Compress PDF

Reloads and saves your PDF with object streams enabled. Size reduction varies; image-heavy scans may change little. No server upload.

Reduce PDF file size in the browser

Email providers and government portals often enforce strict upload limits. Compressing a PDF can make the difference between an accepted application and a bounced message. ToolFest re-saves your PDF with efficient object streams where possible. Results vary: text-heavy office PDFs usually shrink more than scanned photo pages, which are already compressed images.

Compare the before and after sizes shown on the page. If the file grows, your PDF may already be optimised; in that case try reducing image resolution at scan time or use an image tool first.

True “print quality” compression usually needs server-side rasterization. This tool is honest, fast, and private — good for many office PDFs.
