Why convert BMP to TIFF?

TIFF is widely supported by professional image editors, print workflows, and document management systems, while BMP is limited to Windows. TIFF also supports lossless compression (LZW), reducing file size while preserving every pixel — something BMP cannot do. Converting to TIFF gives you broader software compatibility without sacrificing image quality.

Does this tool preserve image quality?

Yes — the conversion is fully lossless. BMP stores raw uncompressed pixels; the converter reads those pixels exactly and writes them into a TIFF container. No pixels are resampled, color-shifted, or compressed with lossy algorithms.

Does my data get uploaded to a server?

Never. All BMP decoding and TIFF encoding happens entirely in your browser using JavaScript. Your images never leave your device.

BMP to TIFF Converter

Convert BMP bitmap images to lossless TIFF format entirely in your browser. Every pixel is preserved — no quality loss, no resampling. Batch convert multiple BMP files, preview thumbnails, download individually or as a ZIP. No uploads, no account required.

What This Tool Does

Converts BMP bitmap images to TIFF (Tagged Image File Format) entirely in your browser. The conversion is fully lossless — every pixel from the source BMP is written exactly into the TIFF output with no resampling, color shifting, or quality degradation. No server upload, no account, no file size limits imposed by a backend.

Who This Is For

Photographers and designers who need BMP images in TIFF for professional editing workflows in Photoshop or Lightroom
Print professionals who require TIFF files for prepress, publishing, and archiving purposes
Developers and archivists migrating legacy BMP assets into the more portable and better-supported TIFF format
Anyone who needs to convert BMP graphics for use in software that doesn't support BMP natively

Example: Input: logo.bmp (Windows bitmap) → Output: logo.tiff (lossless, ready for print or professional editing)

💡 Need a compressed web-compatible format? Try BMP to AVIF for modern web use. To convert BMP to a favicon icon, use BMP to ICO. For TIFF to other formats, see TIFF to JPG or TIFF to PNG.

How It Works

Drop your BMP filesDrag one or more .bmp files onto the drop zone, or click Browse Files. Thumbnails generate immediately from the raw pixel data.

Click Convert to TIFFThe browser reads each BMP into a canvas element, extracts the raw RGBA pixel data, and writes a standards-compliant TIFF file in memory using UTIF.js.

Download your TIFFsDownload files individually or check "Download as ZIP" for a single timestamped archive. The tool resets after export.

🔒 Privacy & Security

All decoding and encoding runs entirely in your browser. BMP files are never sent to any server — they stay in your browser's memory from load to download. This is especially important for sensitive business assets, legacy graphics, or confidential documents.

BMP vs TIFF: Format Comparison

Property	BMP	TIFF
Primary use	Legacy Windows graphics, raw bitmaps	Professional photography, print, archiving
Compression	None (uncompressed by default)	LZW, ZIP, or uncompressed — lossless options
File size	Very large (no compression)	Smaller with LZW; same quality
Color depth	1–32 bit	1–128 bit, including HDR
Transparency (alpha)	Limited (32-bit BMP only)	Full RGBA transparency supported
Multi-page support	No	Yes — multiple images in one file
Platform support	Windows-native; limited elsewhere	Universal — all OS and editing apps
Best for	Legacy Windows applications	Print, scanning, professional workflows

Frequently Asked Questions

Is the TIFF output lossless?▼

Yes — the conversion is fully lossless. The BMP pixel data is read directly from the canvas and written to TIFF without any resampling or compression that would affect quality. What goes in comes out pixel-perfect.

Can I convert multiple BMP files at once?▼

Yes — drop up to 25 or more files at once. The tool processes them sequentially, shows per-file status badges, and lets you download all TIFFs individually or as a single timestamped ZIP.

Does the TIFF support transparency?▼

Yes — the output TIFF is written as 32-bit RGBA, which supports full alpha channel transparency. If your source BMP contains an alpha channel (32-bit BMP), it will be preserved in the output.

Is this tool free with no limits?▼

Yes — completely free with no file size limits, no per-conversion limits, and no account required. Processing happens in your browser so we never see your files.

What software opens TIFF files?▼

TIFF is supported by nearly every professional imaging application: Adobe Photoshop, Lightroom, GIMP, Affinity Photo, CorelDRAW, and all major scanning and print software. macOS Preview and Windows Photos both open TIFF natively.

What is the ZIP file named?▼

The ZIP is named dataconversioncenter_bmp_to_tiff_YYYYMMDDHHMM.zip using your local time — for example dataconversioncenter_bmp_to_tiff_202603061709.zip.
