Convert PNG to PDF in Batch on Windows

You have a folder of PNG images — screenshots, scanned pages, product photos, diagrams — and you need to hand them off as a single PDF or a set of PDF files. Sending dozens of separate PNGs is unwieldy. Uploading them one by one to an online converter is slow and leaks your files to a third-party server. Total Image Converter converts entire folders of PNG files to PDF in one run, with full control over page size, orientation, and whether images are merged into one document or saved as individual PDFs.

PNG vs. PDF: What Is the Difference

PNG is a lossless raster format. It stores pixels with no quality degradation, supports a full alpha channel, and is the standard format for screenshots, UI graphics, and web images. One PNG file is one image.

PDF is a document format. It can contain multiple pages, embed raster images at any resolution, and is universally accepted by printers, email clients, and document management systems. Converting PNG to PDF makes images printable at exact dimensions and lets you package a set of images into one deliverable file.

How to Convert PNG to PDF in Batch

1. Download and install Total Image Converter. The 30-day trial is fully functional — no email or credit card required.
2. Open the program. In the left panel, navigate to the folder containing your PNG files. Thumbnails appear in the file list on the right.
3. Select files: click one file, Shift-click for a range, or press Ctrl+A to select all PNG files in the folder.
4. Click the PDF button in the toolbar. The conversion options dialog opens.
5. Set page size (A4, Letter, or a custom size in inches), orientation (portrait or landscape), and choose whether to merge all images into one PDF or save each PNG as a separate PDF file.
6. Choose the output folder and click Start. All selected PNG files are converted and saved.

Command-Line PNG to PDF

Total Image Converter includes a command-line version for automation and server use. To convert all PNG files in a folder to individual PDF files:

TotalImageConverter.exe C:\Images\*.png C:\Output -c pdf

To convert all PNG files to a single multi-page PDF with A4 page size:

TotalImageConverter.exe C:\Images\*.png C:\Output -c pdf -multipage -paper A4

Use these commands in .bat files or scheduled tasks to process new PNG files automatically as they arrive in a folder.

Why Use Total Image Converter

Merge a folder of PNGs into one multi-page PDF

Enable the multipage option and every selected PNG becomes one page in a single PDF document. Files are added in the order they appear in the folder — sort by name or date before converting to control page order. This is the fastest way to assemble a presentation, report, or photo album from individual images.

Full page size and orientation control

Choose from standard paper sizes (A0–A6, Letter, Legal, Ledger) or enter a custom width and height in inches. Set portrait or landscape orientation per batch. The image is scaled to fit the page with the original aspect ratio preserved — no distortion, no cropping.

Merge into one PDF or keep files separate

Need one PDF per PNG for an automated document workflow? Leave multipage off and each image becomes its own PDF file, named to match the source. Need a single bundle for email or printing? Turn multipage on. Both modes run in the same interface without changing any other settings.

Runs entirely offline

All processing happens locally on Windows. Your PNG files never leave the machine. There is no upload limit, no queue, and no account required. Medical images, legal documents, and confidential screenshots stay private.

Personal license from $49.90

One-time payment. Free updates and technical support included. Works on Windows 7, 8, 10, and 11. A command-line server version (Total Image Converter X) is also available for integration into server workflows.

Total Image Converter Customer Reviews 2026

"We scan every client intake form as PNG and need a single PDF for each case file. Total Image Converter converts the whole day's scans in one batch overnight. The multipage merge option puts each case's pages into one PDF automatically. Saved us about two hours of manual work per week."

Karen Whitfield Office Manager, Legal Services

"I export client mockups as PNG and bundle them into a PDF for review. This used to mean dragging files into Acrobat one at a time. Now I drop everything into a folder, run Total Image Converter with the multipage option, and the PDF is ready in seconds. Page size and orientation controls work exactly as expected."

Tobias Reimer Graphic Designer

"We integrated the command-line version into our document processing pipeline. PNG thumbnails generated by our rendering service get converted to PDF automatically via a scheduled task. The -multipage and -paper flags cover everything we need. Solid tool, no licensing headaches."
