Reliable pdf to word
Date: Feb 03 2026SummaryHad to go back and edit a few old contracts that were only in PDF form. Accuracy of conversion was about 95%, which is pretty good considering the documents were scanned from an old machine. Took about 10 minutes to clean up formatting errors in three documents compared to hours it would've taken to retype everything. Highly recommend for anyone with old documents that need to be edited.
PositiveManaged to turn a few scanned contracts into Word documents that could be edited, and the accuracy of the text scanning was surprisingly good even for scanned documents from an old machine. Formatting was preserved, which was a huge time-saver compared to having to manually clean up scanned documents.
NegativeSometimes the tables end up a little wonky and need to be tweaked, but at least it's quicker than having to retype everything.

Excel to PDF nailed it
Date: Feb 24 2026SummaryThe quarterly budget spreadsheets had to be sent out as locked PDFs for board review. The PDF was an exact replica of the original Excel spreadsheet, which saved a round of reformatting 😊
PositiveThe Excel to PDF conversion was perfect in retaining column widths, borders, and conditional formatting colors. Even multi-sheet workbooks were exported into a single file.
NegativeA page break preview before export would be useful for longer spreadsheets.

Decent compression but limits exist
Date: Jan 22 2026SummaryI wanted to attach a presentation to a client through email and it exceeded mail limit constraints. Using the compress feature in zendocs helped me reduce its size sufficiently without compromising image quality. This isn’t one of those platforms offering a multitude of tools; however, this helps to facilitate what is advertised. Split a very large file to overcome certain mail-size constraints.
PositiveCompression shrunk the size of my presentation from 28MB to 11MB, which was sufficient to send by email. Image quality was still okay for sharing. It has a neat interface that took no more than 30 seconds to complete the process.
NegativeFree tier also has restrictions on file size, which forced me to zip in two installments in bigger projects – would have been better with larger limitations.

Efficient annotate for team feedback

Plus, the merging feature is very nice for putting together different design iterations into one presentation.
NegativeI would appreciate it if there were a feature for adding a custom filename before download instead of just having the default one generated. It's a small workflow improvement that saves me a renaming step afterwards.

Reliable fillable form handling
Date: Dec 09 2025SummaryI completed application forms over several days, saved drafts, and returned without losing data. The ability to pick up where I left off was a lifesaver. Autofill would speed up repetitive info entry, but otherwise very reliable.

Good for quick edits
Date: Nov 17 2025SummaryI needed to mark up a project plan PDF and send it back to a colleague. ZenDocs let me do it directly in the browser without creating a new file version. It's a lightweight solution for collaborative editing when you don't need full Acrobat functionality.
PositiveThe annotation tools meet most of my requirements when adding comments, highlighting texts, and drawing basic shapes. I use this while giving feedback on draft documents coming from my team.
NegativeThe color palette for the highlighter and drawing tools is a bit limited. I would love to have a custom color picker in order to match our brand colors for more formal review cycles, but for internal notes, it's fine.
