Why are BMP files so large?

BMP stores images uncompressed, meaning every pixel's color data is saved directly. This ensures perfect quality but creates larger files.

Which bit depth should I choose?

For most purposes, 24-bit is the best choice. Choose 32-bit only if you need transparency, and 8-bit for simple graphics with few colors.

About BMP: Bitmap format is uncompressed, resulting in larger files but perfect quality. Ideal for Windows applications, printing, and when you need pixel-perfect output. For smaller files, try TIFF to JPG or TIFF to PNG.

How to Convert TIFF to BMP

Upload your TIFF images by dragging and dropping or clicking the upload area. Multi-page TIFF files are fully supported.

Choose page handling: Select whether to convert all pages or just the first page from multi-page TIFF files.

Select bit depth: Choose 24-bit for standard images, 32-bit for transparency, or 8-bit for smaller files.

Optional resize: Enable resizing by percentage or specific dimensions if needed.

Convert and download: Click convert and download individual files or all as a ZIP archive.

Pro tip: Use our TIFF Analyzer first to check your file properties, including page count and color depth. For web use, consider TIFF to JPG for smaller files.

TIFF vs BMP Comparison

TIFF

Tagged Image File Format supports multiple pages, layers, and various compression methods. Commonly used in scanning, printing, and professional photography. Files can be large but preserve maximum quality. Convert to other formats with our TIFF converters.

BMP

Windows Bitmap format stores images uncompressed, resulting in larger files but perfect pixel-for-pixel quality. Universal Windows support, ideal for CAD software, legacy applications, and when compression artifacts are unacceptable. Try BMP to JPG for smaller web-ready files.

Understanding Bit Depth

24-bit

Best for most images. Supports 16.7 million colors (8 bits per channel for RGB). Standard choice for photos and detailed graphics. Compatible with virtually all software.

32-bit

Includes transparency. Adds an alpha channel to 24-bit color. Use when your TIFF has transparent areas you want to preserve. Note: Not all BMP viewers support 32-bit transparency.

8-bit

Smaller file size. Limited to 256 colors using a color palette. Good for simple graphics, icons, or when file size matters. May show banding on gradients or photos.

When to Use BMP Format

Windows Applications

Native format for Windows, supported by all Microsoft software without additional codecs.

CAD Software

AutoCAD and similar programs often prefer BMP for precise image handling.

Print Production

Uncompressed format ensures no quality loss for professional printing.

Legacy Systems

Older software and embedded systems often require BMP format specifically.

Frequently Asked Questions

TIFF files can contain multiple pages (common in scanned documents). Our converter can extract all pages as separate BMP files, or just the first page if you prefer. Each page becomes an individual BMP file named with the page number. For document-focused needs, check our Image to PDF converter.

BMP stores images uncompressed, meaning every pixel's color data is saved directly. A 1920x1080 image at 24-bit color takes about 6MB. This ensures perfect quality with no compression artifacts, but creates larger files. If file size matters, consider TIFF to JPG or TIFF to PNG instead.

For most purposes, 24-bit is the best choice - it supports full color and works everywhere. Choose 32-bit only if your TIFF has transparency you need to preserve. Use 8-bit for simple graphics with few colors, or when you need the smallest possible BMP file size.

Yes, 32-bit BMP includes an alpha channel for transparency. However, not all software properly displays BMP transparency. For reliable transparency, TIFF to PNG is usually a better choice as PNG transparency is universally supported.

Yes, each file can be up to 25MB, and you can upload up to 10 files at once. This accommodates most TIFF files. For very large TIFFs, consider using the resize option to reduce dimensions before conversion, or try our TIFF Resizer first.

Our converter handles all common TIFF compression methods including uncompressed, LZW, ZIP/Deflate, JPEG, PackBits, and CCITT (fax) formats. This covers virtually all TIFF files you'll encounter.
