How to Batch Convert To PDF
When you have dozens of Word documents, Excel spreadsheets, images, and presentations that all need to become PDFs, converting them one by one is tedious and error-prone. Batch conversion processes your entire folder of files in one operation, applying consistent settings to every document. SublimePDF's batch converter handles mixed file types and outputs a ZIP of individual PDFs or a single merged document.
Follow the step-by-step instructions below, then use the free tool directly — no registration or download required.
Open Tool →How to Batch Convert To PDF — Step by Step
Upload your files
Open the Batch Convert to PDF tool and drag all files onto the upload area. You can mix file types freely—Word (.docx), Excel (.xlsx), PowerPoint (.pptx), images, HTML files, and plain text are all supported.
Review the file list
The tool displays all uploaded files with their detected type, size, and estimated output. Check that all files were recognized correctly. Remove any files you uploaded by accident.
Set conversion preferences
Configure global settings: PDF page size for non-PDF inputs, image quality, whether to include metadata from source files, and how to handle fonts (embed all fonts for guaranteed fidelity).
Choose output format
Select 'Individual PDFs' to get a ZIP archive with one PDF per input file (preserving original filenames), or 'Merged PDF' to combine all converted files into a single document in the order listed.
Convert and download
Click 'Convert All' and monitor the progress bar as each file is processed. Failed conversions are flagged with error details. Download the completed output as a ZIP or merged PDF.
Pro Tips
- 💡 Name your files consistently before uploading—the output PDFs inherit the source filenames, so 'Report_Q1_2026.docx' becomes 'Report_Q1_2026.pdf.'
- 💡 For PowerPoint files, the conversion preserves slide layouts, transitions are ignored, and speaker notes can optionally be included as separate pages.
- 💡 If some files fail to convert, check that they aren't password-protected or corrupted. Re-save them from their original application and try again.
- 💡 Use batch conversion at the end of a project to archive all working files as PDFs in one shot, ensuring long-term accessibility regardless of software changes.
Privacy & Security
All processing happens directly in your browser. Your files are never uploaded to any server — they remain on your device throughout the entire process. SublimePDF uses WebAssembly technology for fast, secure, client-side processing.
Works Everywhere
This tool works on any modern browser — Chrome, Firefox, Safari, or Edge — on desktop, tablet, or mobile. No software to install. PDF is an open ISO standard supported by all major platforms.

How to Convert PDF To Grayscale
Printing color PDFs on black-and-white printers often produces muddy, hard-to-read output because the printer's automatic color conversion isn't optimized for clarity. Pre-converting your PDF to grayscale ensures consistent, clean results on any mono printer and can dramatically reduce printing costs for large jobs. SublimePDF converts all colors—in text, images, and vector graphics—to properly weighted grayscale.
