Linearization (also called 'Fast Web View') restructures the internal layout of a PDF so that a web browser or PDF viewer can begin displaying the first page while the rest of the file is still downloading. This is especially valuable for large PDFs hosted online, reducing perceived load times significantly.
A regular PDF stores its data in no particular order — a browser must wait for the full file to download before rendering anything. A linearized PDF places all data needed for the first page at the very start of the file, enabling progressive rendering and a much faster user experience for online documents.
No. Linearization only reorganizes the internal structure of the file. The text, images, fonts, and formatting of your PDF remain completely unchanged. The file size stays approximately the same.
Yes! You can upload as many PDF files as you need. Each file is linearized independently in your browser, and all results are packaged into a single ZIP archive for convenient download.
