You have a folder with Word files, scanned TIFFs, Excel sheets, Outlook emails and a few HTML pages, and the person asking for them wants one set of PDFs. Running five different converters for that is slow and easy to get wrong. Coolutils Converter is built to take that whole mixed pile in one batch.
Quick facts
- Platform: Windows (7, 8, 10, 11; Windows 2000 is also listed)

- Trial: 30-day free trial, plus a 30-day money-back guarantee

Key features
Convert mixed file types in a single batch
Input formats include PDF, XPS, EPS, PCL, HTML, DOC, DOCX, RTF, XLS, XLSX, TIFF, JPG, MSG and EML, plus Outlook emails. Newer additions cover PowerPoint and OpenDocument presentations, OneNote sections and OFD files, the Chinese e-invoice format. You choose the files, pick a target format and apply your settings.
Stamp page counters, Bates numbers and watermarks
You can add headers, footers, page counts, date stamps, any custom text and image watermarks such as a logo. The same tools handle Bates stamping, which matters for legal and e-discovery work.
Archive-ready PDF/A output and protected PDFs
Save to PDF/A for long-term records. For ordinary PDFs you can set permissions (view, print, edit, annotate), add a password, or sign with a digital certificate.
Combine, rename and preview inside the app
It can merge documents within folders and rename output files with counters or dates. A preview panel and a Filter tab let you sort the list by name, date, type or size and check a file before converting it.
Command line and a server version
The GUI can produce a ready-to-use command line for your settings. For silent server work there is a separate ConverterX SDK with no interface or popup messages.
Who it's for
It suits people who regularly convert large, mixed batches: legal teams, e-discovery and forensics staff, accountants handling invoices and tax documents, and anyone archiving old project files. If you only convert a single Word file now and then, a dedicated single-format tool will do.
