How to do it
Add your file
Add the PDF you publish on a website or send as a link — a catalog, a manual, a report people open in a browser.
Set it up the way you want
There is nothing to set. The file is restructured so what a reader needs first comes first, and cleaned up losslessly on the way.

Download the result. It is the same document, arranged so the first page can appear before the rest arrives.
Questions about Optimize PDF for web
- Will my file get smaller?
- Often a little, never at the cost of quality. Alongside the reordering, duplicate and unused parts are dropped and the internal data is re-packed with the strongest lossless setting — text and images stay exactly as they are. A very tightly made file can grow slightly, because the page index this adds outweighs the cleanup. For a much smaller file, use Compress PDF.
- How does that work?
- A normal PDF keeps the index of where everything lives at the end, so a reader has to fetch the end before it can draw anything. Optimized files put that index at the front and group each page’s objects together, which lets a browser request just the first page.
- Do I need this for a file I send by email?
- No. It only helps when the file is being streamed over a network — a website, a document viewer, a link people click. An attachment is downloaded whole before it opens, so the arrangement makes no difference.
