Linearizing PDFs
Linearization (also called Fast Web View) restructures PDFs so the first page can show before the whole file has downloaded. A normal PDF often has to arrive completely before a browser can show it. A linearized PDF lets the first page display while the rest loads in the background. Big improvement for large PDFs on websites, slow connections and mobile viewing.

Upload
- Upload your PDF, or several at once. Up to 100 MB each.
- Shows filename and original size.
- Each file is checked to be a real PDF.
Settings
- No profiles to pick:
- One job: the file is rewritten in linearized order with the qpdf engine.
- No compression: pages, images and fonts are not changed, so the file size stays about the same.
- Need a smaller file as well? Run it through Compress PDF first, then linearize it.
Optimize
- Hit "Optimize for web".
- Progress bar shows the upload and the processing.
- Process: the PDF is reorganized so the first page data comes first, with hint tables that tell readers where each page is.
Result
- After completion:
- A linearized copy is ready to download.
Download
- Click download to save the file.
- Saves as "filename-web.pdf".
- Looks identical, but the first page can show sooner on the web.
- Upload it to your website and open the link to see the first page appear quickly.
How to Check
- In Adobe Acrobat or Reader, open File, then Properties.
- Look for Fast Web View: Yes. That's linearization working.
- Other readers may not show this setting.
What Is Linearization?
- Restructures PDF so page 1 content is at the file beginning.
- Browsers can display first page immediately using byte-range requests.
- Rest of pages load in background as you scroll.
- Without: a large PDF may have to download completely before page 1 appears.
- With: page 1 can show early while the rest loads, if the web server supports byte-range requests.

- Faster first page: less waiting on large files.
- Better experience: readers can start reading sooner.

Frequently asked questions
What does it mean to linearize a PDF?
Linearizing, also called Fast Web View, reorganizes the inside of a PDF so the data for the first page comes first. A browser or PDF reader can then show page one while the rest of the file is still downloading.
How do I linearize a PDF?
Add one or more PDFs and click Optimize for web. You download a linearized copy with -web added to the file name.
Will linearizing change my document or make it smaller?
No. The pages look exactly the same and the file size stays about the same. Only the order of the data inside the file changes. To make a file smaller, use Compress PDF.
When is Fast Web View useful?
It helps with large PDFs that people open from a website, such as catalogs, manuals, brochures and reports. The web server must support byte range requests, which most modern servers do.
How can I check that a PDF is linearized?
In Adobe Acrobat or Reader, open File, then Properties, and look for Fast Web View: Yes. Other readers may not show this setting.
Is my file safe?
Linearizing runs on our own server. The file is sent over an encrypted connection and deleted right after processing. Files can be up to 100 MB.
