Linearize PDF

About PDF Linearization

This tool optimizes PDF files for fast web viewing (also known as linearization or Fast Web View). Linearized PDFs can be displayed in a web browser before the entire file is downloaded, providing a better user experience for large documents.

What is PDF linearization?

PDF linearization (Fast Web View) reorganizes the internal structure of a PDF so that the first page can be displayed immediately while the rest of the document continues to download. This is essential for PDFs served over the web.

Why should I linearize my PDFs?

Linearized PDFs provide a better user experience on websites. Visitors can start reading the first page immediately instead of waiting for the entire file to download. This is especially important for large documents.

What does Object Streams do?

Object Streams is a PDF feature that groups multiple small objects together, reducing file size and improving loading performance. It's recommended to keep this option enabled for web-optimized PDFs.

Should I remove metadata?

Removing metadata can slightly reduce file size and increase privacy by removing author name, creation date, and other document information. Enable this if you want to strip personal information from the PDF.

What is the file size limit?

The maximum file size is 50MB. This ensures smooth performance in your browser. For larger files, consider using desktop PDF software like Adobe Acrobat or qpdf.

Is my PDF file safe?

Absolutely! All PDF processing happens directly in your browser. Your PDF file is never uploaded to any server. Everything stays private on your device.

How do I check if a PDF is linearized?

After loading a PDF, this tool shows the 'Web Optimized' status. In Adobe Acrobat, you can check File > Properties > Description > Fast Web View to see if a PDF is linearized.

Will optimization affect PDF quality?

No, this optimization only restructures the PDF internally. All content, images, and formatting remain exactly the same. Only the file structure is reorganized for faster web delivery.
