PDF Linearize
Prepare a PDF for fast web view with our PDF Linearize tool. It rewrites the file with qpdf so the first page and its resources come first and adds the hint tables viewers use to jump to any page, letting browsers show page one before the whole download finishes. Upload a PDF up to 10 MB and 200 pages, such as a manual, catalog or report you publish on a website.
Frequently asked questions
What does linearizing a PDF mean?
A linearized PDF stores the objects of the first page at the start of the file and adds hint tables that say where every other page lives. Viewers can then display the first page and fetch later pages on demand instead of waiting for the entire file.
Is linearization the same as Fast Web View?
Yes. Adobe Acrobat calls a linearized file Fast Web View and shows Yes for it in the document properties. The output of this tool reports as linearized there and in qpdf.
When does fast web view help?
It helps when a large PDF is opened from a web server that supports byte range requests, which most servers and CDNs do. The viewer requests the parts it needs first, so readers see content sooner on slow connections.
Does linearizing make the PDF smaller?
No. Linearization reorders the file and adds hint tables, so the size stays about the same or grows slightly. Use PDF Compress first if you also want a smaller file, then linearize the result.
Does it change how the PDF looks?
No. Pages, text, images, links, bookmarks and form fields stay exactly as they were. Only the order of the objects inside the file changes.
Can I linearize a password protected PDF?
Yes. Enter the password in the Password field and the output keeps the same protection, so readers still need the password to open it.
What are the limits?
You can upload one PDF of up to 10 MB with at most 200 pages. Processing stops after 20 seconds, which is far more than linearizing a file of that size takes.
Should I linearize again after editing the PDF?
Yes. Most editors append their changes as an incremental update, which breaks the linearized layout. Run the edited file through the tool once more before publishing it.
What is the result called?
The download keeps the original name with -linearized added, so manual.pdf becomes manual-linearized.pdf. Rename it before uploading if your links expect the old name.
Is my PDF kept after processing?
No. The file is handled in memory for this request and discarded when the download is ready. Nothing is written to disk or shared.
