Compress PDF Online Privately and Offline

Large PDF documents are difficult to share over email or upload to forms. Amendly PDF Studio provides an adjustable slider-based compression tool that shrinks PDF file sizes completely inside your local browser. No cloud uploads, no server delays.

🎛️ Target Size Percentage Control

Drag the compression slider to set your target percentage size. The tool will calculate the expected output size dynamically and balance quality and speed to match your requirements.

🖼️ Preservation of Font and Text Details

Our optimizer compresses inline image metadata, streams, and redundant vectors while preserving original embedded font glyphs, styles, and high-fidelity text vectors for perfect readability.

Frequently Asked Questions — PDF Compression

How much can I reduce my PDF size?

Typically, documents with scanned page images can be reduced by 50% to 80% without noticeable quality loss. Pure text vectors will see minor changes as they are already highly optimized.

Are my PDF files safe during local compression?

Yes. Traditional PDF compress services transmit files to their remote clusters. Amendly processes the PDF stream directly in your browser's memory, meaning your files never leave your machine.

Does this support PDF standard guidelines?

Yes, our client-side compression preserves PDF structure parameters, keeping them compliant with standard viewers, Acrobat, and web browser readers.
