What is the difference between shrinking and compressing a PDF?

"Shrinking" and "compressing" a PDF mean the same thing — reducing the file size. Both terms describe re-encoding the file to use less storage space. FixTools uses the terms interchangeably.

How fast does FixTools shrink PDFs?

For most PDFs under 10MB, shrinking takes under 10 seconds on a modern device. Larger files (50MB+) may take 30–60 seconds depending on page count and image density.

Does shrinking a PDF change the page layout?

No. Compression only changes the internal encoding of images and the efficiency of data storage. Page dimensions, margins, fonts, and layout remain exactly the same in the output PDF.

Can I shrink a PDF on my phone?

Yes. FixTools works in mobile browsers on both iPhone and Android. The upload, compress, and download workflow is identical — just tap instead of click.

Will shrinking a PDF remove bookmarks or hyperlinks?

No. FixTools compression preserves PDF structure including bookmarks, hyperlinks, form fields, and annotations. Only image quality is reduced — all navigational and interactive elements remain intact.
