Fast local batch conversion
Batch PDF converter for Windows.
CometPDF lets you convert many files in one run instead of opening every document manually. Add Word documents, Excel spreadsheets, PowerPoint presentations, images, emails, text files, or PDFs, choose an output folder, and create the results locally on Windows.
Batch conversion is useful for office teams, freelancers, accounting work, project folders, document archives, scan folders, and email records. It saves time while avoiding browser uploads, online queues, account limits, and repeated manual export steps.
CometPDF supports batch conversion to PDF, optional merge to a single PDF, and reverse PDF export batches for images, text, Word, and PowerPoint.

Convert many files
Add multiple supported files and let CometPDF process them in one batch instead of exporting one by one.
Merge outputs
When useful, combine converted PDF outputs into a single PDF for delivery, archiving, or review.
Stay local
Batch jobs run on your computer, making the workflow practical for sensitive folders and internal documents.
Batch workflows
Real document work rarely involves one file at a time. A folder may contain proposals, spreadsheets, scanned images, emails, reports, and attachments that all need PDF copies. CometPDF is built for that kind of mixed batch: select the files, choose the conversion mode, and produce outputs without opening each source file manually.
When Microsoft Office, Outlook, or LibreOffice are installed, CometPDF can use them for print-like PDF output. That helps preserve page orientation, print areas, slide proportions, Word headers, and other formatting details while still giving users a simple batch interface.
FAQ
Can CometPDF convert multiple files at once?
Yes. Add multiple supported files and run them in one batch. This is useful for folders of documents, emails, images, reports, or mixed office files.
Can it merge converted PDFs?
Yes. CometPDF can optionally merge PDF outputs into a single file after conversion. This is useful when many documents need to be delivered or archived together.
Does batch conversion upload files?
No. Batch conversion happens locally on your Windows computer. CometPDF does not send your selected files to a server.
Which file types can be batch converted?
CometPDF supports DOC, DOCX, RTF, XLS, XLSX, XLSM, PPT, PPTX, MSG, EML, JPG, PNG, WEBP, BMP, TIFF, TXT, CSV, HTML, XML, JSON, and PDF export modes.
Does it support reverse PDF batch conversion?
Yes. CometPDF 1.1 can batch export PDFs to PNG, JPG, TXT, DOCX, and PPTX. Visual export modes preserve page appearance rather than rebuilding every object as editable content.
