How to Merge TIFF Files into One Multi-Page Image

Scanners, fax machines, and document management systems often produce dozens of single-page TIFF files for what is logically one document. Reassembling them by hand — opening each file, copy-pasting pages, adjusting settings — takes too long once you pass five or ten files. TIFF Combine merges any number of .tif files into a single multi-page TIFF or PDF in seconds.

Why Merge TIFF Files?

• One file instead of many — email a 40-page contract as a single attachment, not 40 separate images.
• Correct page order — sort pages by name, date, or custom order before merging.
• Smaller output — apply LZW, JPEG, ZIP, or CCITT compression during the merge to reduce file size by 30–70%.
• Batch processing — merge thousands of TIFFs across multiple folders in one run.
• Format choice — output as multi-page TIFF or multi-page PDF without a separate converter.

How to Merge TIFF Files: Step by Step

1. Download and install — get the free 30-day trial (6 MB, Windows 7/8/10/11). No email or credit card needed.
2. Add files or folders — click Add Files to pick individual TIFFs, or Add Folder to load an entire directory. Drag-and-drop works too.
3. Choose output format — select multi-page TIFF or PDF in the output settings panel.
4. Set compression and color — pick a compression method (LZW for lossless, JPEG for smaller size, CCITT for black-and-white scans) and color space (RGB, grayscale, B/W).
5. Adjust pages — resize, rotate, or crop pages directly in the app. Reorder them if the default sort is wrong.
6. Click Combine — TIFF Combine creates the merged file. A 500-page merge typically finishes in under a minute.

Merge TIFFs by Filename Pattern

When a folder contains TIFFs from different documents mixed together, TIFF Combine can group files by a common part of the filename. For example, files named invoice_001_p1.tif, invoice_001_p2.tif, invoice_002_p1.tif can be merged into two separate multi-page TIFFs — one per invoice — automatically.

Command-Line Merging

TIFF Combine includes a command-line interface for automation. Example:

TiffCombine.exe /S "C:\Scans\*.tif" /T "C:\Output\merged.tif" /COMPRESS LZW

Wrap the command in a .bat file to run it on a schedule or integrate with a document workflow. The command line supports the same options as the GUI: compression, color space, page order, resize, and rotation.

TIFF Combine vs. Online Merging Tools

Server and ActiveX Edition

For server-side or programmatic use, TiffCombineX provides an ActiveX interface. Integrate TIFF merging into web applications, Windows services, or custom software without a GUI dependency.

When Do You Need to Merge TIFFs?

• Legal and compliance — combine scanned case files or contracts into single documents for filing.
• Medical imaging — merge multi-page patient records stored as separate TIFF scans.
• Architecture and engineering — assemble drawing sets or blueprints into one file for review.
• Accounts payable — group invoice pages that arrive as individual TIFF attachments.
• Digital archiving — consolidate scanned books or periodicals into properly ordered multi-page TIFFs.
