Convert BMP to TIFF in Batch on Windows

BMP files accumulate whenever you work with legacy Windows applications, scanner software, or older CAD and paint tools that output uncompressed bitmaps by default. The format is fine for local editing but impractical for print workflows, document archiving, or any process that expects TIFF. Print shops, document management systems, and medical imaging software all expect TIFF — not BMP. Total Image Converter converts BMP to TIFF in batch, preserving color depth and letting you choose the compression method for the output file.

BMP vs. TIFF: What Is the Difference

BMP has no compression and no multi-page support. It is adequate for Windows-internal use but not suited for print prepress, archiving, or cross-platform delivery. TIFF supports lossless compression, multi-page files, and is the standard format for print production and document archiving systems.

How to Convert BMP to TIFF 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 BMP files. Thumbnails appear in the right panel.
3. Select the files you want to convert: click one file, Shift-click for a range, or press Ctrl+A to select every BMP in the folder.
4. Click the TIFF button in the format toolbar at the top of the window.
5. In the conversion options dialog, choose the TIFF compression method: LZW for smaller files, ZIP for maximum compression, or None to keep the output uncompressed. You can also set color depth, DPI, and multi-page options here.
6. Choose the output folder and click Start. All selected BMP files are converted to TIFF and saved.

Command-Line BMP to TIFF

Total Image Converter includes a command-line executable for server use, scripted workflows, and automated batch jobs. Convert all BMP files in a folder to TIFF:

TotalImageConverter.exe C:\Scans\*.bmp C:\Output -c tiff

To convert with LZW compression explicitly set:

TotalImageConverter.exe C:\Scans\*.bmp C:\Output -c tiff -TIFFCompression lzw

Save either command in a .bat file and run it from Task Scheduler to automate nightly or post-scan conversion without any manual steps.

Why Use Total Image Converter

Batch conversion without a file count limit

Select an entire folder or use Ctrl+A to process hundreds or thousands of BMP files in one run. The conversion runs in the background — you do not need to click through each file individually.

TIFF compression options: LZW, ZIP, or None

Not all TIFF files are equal. Print prepress often requires uncompressed TIFF. Archiving benefits from LZW, which reduces file size by 40–60% for typical scanned documents without any quality loss. ZIP compression achieves even higher ratios for some content. You choose the method per conversion job.

Color depth preserved exactly

A 24-bit BMP produces a 24-bit TIFF. A 1-bit or 8-bit BMP stays at that bit depth unless you explicitly change it. No silent conversion to a different color space or unwanted dithering.

Resize and crop in the same pass

Set a target resolution or crop margins in the options dialog. The program applies both the format conversion and the geometry change in one step, without creating intermediate files.

Works offline, files stay local

Everything runs on your Windows machine. No files are uploaded to any server. This matters when converting medical records, scanned contracts, or any documents that must not leave the local network.

Total Image Converter Customer Reviews 2026

"Our prepress department receives BMP files from a client who runs legacy measurement software that cannot export anything else. We convert the entire delivery folder to TIFF with LZW compression before it goes into the RIP. Total Image Converter handles the batch in under two minutes and the output drops straight into our imposition workflow without any complaints from the software."

Thomas Brennan Print Production Specialist

"We digitize records from older Windows scanning stations that produce BMP output. Before ingestion into our TIFF-based archive, every file has to be converted. The command-line version of Total Image Converter runs as a scheduled task every night, converting whatever landed in the intake folder. Multipage TIFF output groups related pages into single files exactly as our indexing system expects."

Christine Vogel Document Archivist

"Our older radiology workstations export annotated screenshots as BMP. The document management system we use for patient records only accepts TIFF. Total Image Converter converts the exports reliably — color depth is preserved and the files pass validation without any issues. Batch processing is fast enough that staff can run it manually at the end of a shift. A watched-folder mode would make the workflow fully automatic, but the current solution does the job."
