True linearization
The file is rewritten with a linearization dictionary and hint tables, the standard Fast Web View format.
Fast web view · Free · No upload
Make a PDF open faster on the web.
Linearization (Fast Web View) reorders a PDF so browsers can show page one while the rest is still loading. YaPDF runs qpdf in WebAssembly to do it on your device.

03 · WHAT YOU GET
Standards-based optimization.
Every feature below runs on your device. See how the engines work.
Compact object streams
Objects are grouped into compressed streams, often trimming file size.
Lossless
Fonts, images and vector content are copied unchanged.
Proven engine
qpdf is the same tool used in professional pipelines, compiled to WebAssembly and run locally.
Does linearizing reduce file size?
Sometimes, thanks to object streams, but the goal is faster first-page display rather than compression. Images are not recompressed.
When does Fast Web View matter?
When a PDF is served from a web server that supports byte-range requests. Local files and email attachments open the same either way.
Can I linearize a protected PDF?
Unlock it first, then optimize the unlocked copy.
