Batch Rename TIFF Files and Convert Images to TIFF on Windows

Managing large sets of figures or images often becomes tedious when filenames are inconsistent or when a specific format such as TIFF is required for publication, archiving, or processing tools.
This guide shows how to perform two common tasks easily and automatically on Windows:

1. Batch renaming TIFF files
2. Batch converting all JPG/JPEG/PNG images to TIFF

Everything is done using PowerShell and ImageMagick, both free and easy to use.

🔄 1. Batch Rename Numeric TIFF Files to “Fig X.tiff”

If your folder includes names like:

7.tiff
8.tiff
Fig 1.tiff
Fig 2.tiff
9.tiff

…and you want to rename only the plain-number files (e.g., 7.tiff → Fig 7.tiff), while leaving already-correct names unchanged, run this PowerShell command in that folder:

Get-ChildItem *.tiff | Where-Object {
    $_.BaseName -match '^\d+$'
} | Rename-Item -NewName {
    "Fig " + $_.Name
}

✔ What this command does

• Renames only files whose names consist of digits (e.g., 7.tiff, 8.tiff)
• Leaves files like Fig 1.tiff untouched
• Works instantly inside the chosen directory
• No installation required—PowerShell is built into Windows

🖼️ 2. Batch Convert JPG/JPEG/PNG to TIFF Using ImageMagick

To convert your image folder to TIFF format, install ImageMagick if you haven’t already:

👉 https://imagemagick.org

Once installed, open PowerShell in your folder and run:

Get-ChildItem *.jpg, *.jpeg, *.png | ForEach-Object {
    $output = $_.BaseName + ".tiff"
    magick $_.FullName $output
}

✔ What this command does

• Converts every .jpg, .jpeg, and .png file to .tiff
• Keeps the same base name
  (e.g., photo.jpg → photo.tiff)
• Works on an entire folder automatically

🎨 Optional: Higher-Quality TIFF Settings

Use LZW compression (recommended for publication)

magick input.jpg -compress lzw output.tiff

Create 16-bit TIFF files (useful for scientific figures)

magick input.png -depth 16 output.tiff
