What does PDF compression change?

AG File Tools removes common metadata and rewrites the PDF with compact object streams while keeping page content.

Is this the same as Compress PDF to Exact Size?

No. This page reduces size where practical; the exact-size page evaluates a specific KB or MB target.

Will links and selectable text remain in the PDF?

The structural rewrite preserves normal page content, including text and links supported by the source PDF.

Are my files uploaded to your server?

No. Your files never leave your device. Processing happens privately in your browser.

How PDF Compressor works

Compress PDF files online to reduce file size with private browser processing. Remove common metadata and optimize supported PDFs without server upload.

What you provide: A PDF document.
What AG File Tools returns: A structurally optimized PDF when the rewritten file is smaller, otherwise the original-sized result with an honest explanation.
Practical limit: Browser-side structural optimization cannot substantially shrink PDFs dominated by already-compressed images or scanned pages.
