To optimize a PDF for web, also known as fast web view or linearization, is to reorganize the file's internal structure. Instead of requiring the whole file to download before anything appears, linearize PDF moves the first page's data to the front of the document. A reader can then view that page while the rest keeps loading in the background.
This difference matters whenever a document is opened directly in a browser. For a large catalogue, a report of dozens of pages or a brochure shared online, this fast web view clearly improves perceived speed: your readers see content almost immediately, without waiting for a long download to finish. The file's content stays exactly the same; only the way it is served changes.
This optimization makes the most sense when you publish PDFs online: a website, a document portal, a share link or an embed inside a page. To go further, combine it with compress for a smaller file to download, then run web optimization again on the result. If a document looks corrupted or refuses to open, repair can restore its structure before processing, and metadata lets you check or clean the title and author before you distribute it.

Linearisation (or "fast web view") reorganises the internal structure of the PDF so the first page appears before the file has fully finished downloading.
It reorganizes the PDF's internal structure so the first page appears while the rest downloads. The reader sees the beginning of the document without waiting for the full file.
Not necessarily: its purpose is progressive display, not compression. The size stays close to the original and may even grow slightly due to the added navigation information.
