PDF ऑप्टिमाइज़र — मुफ़्त ऑनलाइन

Results vary widely by content: PDFs with many high-resolution images can be reduced 50–80%. PDFs that are mostly text compress 10–20%. Already-compressed PDFs may not reduce significantly. The tool shows the actual reduction before download.

Compression reduces image resolution and quality within the PDF, removes embedded duplicate fonts, and resamples high-DPI images down to screen-appropriate resolution. Text content and layout are not affected.

Text remains crisp at all compression levels — only embedded images are resampled. Light compression keeps images at 150 DPI; Maximum compression reduces to 72 DPI, acceptable for screen viewing but not for print.

Basic compression runs in the browser. For advanced compression (server-side image resampling), files are processed on temporary servers and immediately deleted after download — typically within 30 minutes.

Browser-based compression handles up to 50 MB. Server-side compression accepts files up to 200 MB. For larger files, use a desktop compression tool or Ghostscript from the command line.
