Frequently Asked Questions

What is the maximum file size?

Up to 100MB per file. Premium users can process larger files.

Does this preserve bookmarks and form fields?

Yes. Compression rewrites image streams and re-encodes fonts, but bookmarks, hyperlinks, form fields, and annotations carry over to the smaller file.

What PDF versions are supported?

PDF 1.0 through 2.0. The output PDF version follows the input; downgrades are not performed.
