Optimize a PDF to Load Faster Online
Reorganize a PDF so the first page loads instantly instead of waiting for the whole file.
How it works
1. Upload your PDF. 2. We reorganize its internal structure for progressive loading. 3. Download the optimized file.
What does "fast web view" actually mean?
A linearized PDF lets a browser display page 1 as soon as enough of the file has downloaded, instead of waiting for the entire file — most noticeable on large PDFs over a slow connection.
Does this change how my PDF looks or reduce its size?
No — the content is identical. This only reorders the file's internal structure and adds a small hint table for progressive loading — it's not compression, so don't expect a smaller file (use Compress PDF for that). The hint table can make the file a tiny bit bigger, but you won't notice the difference.
How do I check that a PDF is actually linearized?
Open the file's Properties in Adobe Acrobat or Preview — the Description tab will show "Fast Web View: Yes." No PDF reader handy? Open the file in a plain text editor and look near the very top for /Linearized — that's the marker every linearized file starts with.
Will I notice a difference, or does this only matter for websites?
It only matters when the PDF streams over the web — opened straight from a link, viewed inside a browser tab, or embedded on a page. If someone already has the whole file sitting on their disk before they open it, there's nothing left to speed up. This tool is for PDFs people view online, not ones they've already downloaded.
