Questions about Optimize PDF for Web

What does fast web view mean for a PDF?

Fast web view is another name for a linearized PDF. Without it, a browser may need the whole file before it can show anything. A linearized file puts what the first page needs at the start, so page 1 can appear while the rest downloads. Optimize PDF for Web makes this change for you.

Is Optimize PDF for Web free?

Yes. Optimize PDF for Web is free and unlimited, and you don't need an account. It runs on your device, so there are no daily limits or file counts. The only practical limit is your device's memory, comfortably around 1 GB of PDFs on a computer and less on a phone.

Is my PDF uploaded when I optimize it?

No. Optimize PDF for Web does all its work inside your browser, and your file never leaves your device. That's useful for drafts you haven't published yet. The only time the file goes online is when you upload the optimized copy to your own website yourself.

Will optimizing make my PDF smaller?

Not really. Optimize PDF for Web changes the order of what's inside the file, so the size stays about the same and the pages look identical. What changes is how soon the first page appears in a browser. If you also need a lighter file, run it through Compress PDF first, then optimize the compressed copy.

Does Optimize PDF for Web work on a Mac or Chromebook?

Yes. Optimize PDF for Web works in any modern browser on Mac, Windows, Linux, Chromebook, iPhone, iPad and Android, with no app to install. Open the page, add your PDF, optimize it and save the copy. Then upload that copy to your website the way you normally would.

When is it worth optimizing a PDF for the web?

Optimize PDF for Web helps most with long or image-heavy PDFs that people open from a link, such as reports, catalogs, menus and handbooks. For a short one-page file, the difference is small. It doesn't change how email attachments open, since those arrive in full before anyone can view them.
