SublimePDF vs PDF Bob — FAQ

Is PDF Bob a full PDF tool?
PDF Bob is primarily a PDF editor — it lets you add text, draw, and annotate. It doesn't offer merging, splitting, compression, or format conversion. SublimePDF provides all of these plus editing capabilities.
Can PDF Bob merge or split PDFs?
No. PDF Bob focuses on editing individual PDFs. For merging, splitting, or compressing, you'd need SublimePDF or another full-featured tool.
Which is more private?
SublimePDF — it processes files entirely in your browser. PDF Bob processes files on its servers, meaning your documents are uploaded during use.
Is PDF Bob good for everyday PDF work?
PDF Bob is fine for occasional annotation and text editing on a single PDF. But if you regularly merge, split, compress, or convert PDFs, you'll quickly outgrow its limited feature set. SublimePDF covers the full range of everyday PDF operations.
