An ordinary PDF keeps the index of its objects at the end, so a reader has to fetch the tail before it can draw anything. Over a slow link that is a blank screen until the download finishes.
A linearized PDF puts the first page and the information needed to find it at the front. A browser reading the file over HTTP can render page one while the rest is still arriving.
This is worth doing for a PDF served from a website or an email link. For a file that is downloaded and opened locally it changes nothing the reader notices.
Sometimes, a little. Streams are recompressed losslessly, which helps a file that was written without compression. It is not a size tool: Compress PDF is.
No. Nothing is re-encoded. Images keep their original bytes and text keeps its fonts. The file is reordered, not rewritten.
Most readers show it in the document properties as Fast Web View, with a yes or no. The value should read yes after optimizing.
Not really. Linearizing pays off when a reader can fetch the beginning of a file before the end, which is what a web server allows and an attachment does not.
No. Remove the password first with the Unlock PDF tool, using the password you already know.
