Your BMP file(s) are converted to TIFF automatically. The conversion runs instantly in most cases — single files are typically ready in under two seconds. Batch conversions of multiple files take a few seconds longer depending on file sizes.
Once conversion is complete, click "Download TIFF" to save your converted file directly to your device. For batch conversions, download all files at once as a ZIP archive. No sign-up, no email required — your file is ready immediately.
TIFF supports alpha channel transparency, allowing your converted images to have see-through areas for overlaying on any background. Essential for logos, icons, and layered designs.
BMP files are large; converting to TIFF reduces file sizes by 70–95% through efficient compression, making them practical for web use, email, and cloud storage.
Unlike lossy formats, TIFF can be edited and saved unlimited times without accumulating compression artifacts — the professional standard for archival and editing workflows.
TIFF supports CMYK color mode, multi-page documents, and the color profiles required by professional printing equipment and publishing prepress workflows.
Convert up to 10 BMP files to TIFF simultaneously. Perfect for processing entire photo libraries, design asset collections, or bulk content workflows without converting files one by one.
Our BMP to TIFF converter is completely free. There are no watermarks added to converted images, no file count limits, and no account registration required.
BMP files do not support transparency — any area intended to be see-through is rendered as a solid color (usually white). Converting to TIFF unlocks full alpha channel support, allowing designers to overlay images on colored backgrounds, add watermarks, and create layered compositions. This is essential for logo preparation, icon design, and web UI development.
BMP files are notoriously large — a single BMP image can easily reach 10–100 MB. Converting to TIFF applies efficient compression that can reduce file sizes by 70–95% while maintaining excellent visual quality. This makes images practical for web publishing, email sharing, cloud storage, and faster loading in applications.
When preparing images for professional printing, publishing, or long-term archival, TIFF's lossless compression ensures no data is lost over time or across multiple generations of file handling. Print shops, publishers, and archivists prefer TIFF because it guarantees that the file delivered for printing is pixel-for-pixel identical to the original.

Convert BMP to TIFF when you need transparency in your images, or when you need lossless quality for archiving or repeated editing, or when you need to dramatically reduce the BMP file size.
Converting BMP to TIFF is a common task for web developers, graphic designers, photographers, and anyone working with digital images. Microsoft's native Windows bitmap — uncompressed, universally supported in Windows apps, but very large. The professional standard for printing, archiving, and medical imaging — uncompromising quality in a flexible format. Understanding when and why to make this conversion — and how to do it correctly — can significantly improve your workflow, image quality, and website performance.
The most common reasons to convert BMP to TIFF include: the need for transparency support — TIFF can display images with see-through areas, while BMP cannot; file size reduction — BMP files are extremely large, and TIFF can store the same image data in a fraction of the space. BMP (Bitmap Image File) is Microsoft's native raster image format introduced with Windows 1.0 in 1985. It stores image data with no lossy compression by default, resulting in file sizes that can be 10 to 100 times larger than equivalent JPG files. A full-page 300 DPI scan that would be 2 MB as a JPG becomes 50–100 MB as a BMP. BMP's value lies in its simplicity and universal Windows compatibility — every Windows application that handles images can read BMP files. It's used in legacy software, game development, embedded systems, and situations where raw uncompressed pixel data is required for processing. In contrast, TIFF (Tagged Image File Format) is the gold standard for professional image quality. Developed in 1986 and widely adopted in publishing, medical imaging, and professional photography, TIFF supports multiple compression options (including fully lossless), CMYK color for print workflows, up to 64-bit color depth, multiple pages per file, and alpha channel transparency. A high-resolution TIFF from a professional scanner or camera contains every detail of the original, making it the format of choice for archival, medical records, legal documents, and commercial printing. TIFF's flexibility — it can store virtually any image type in any color space — makes it indispensable in professional workflows, even though it's impractical for everyday use. For use cases where TIFF's characteristics better match your needs — whether that's transparency, lossless quality, smaller file sizes, or broader compatibility — conversion is a straightforward solution.
BMP and TIFF differ in several important ways:
**Compression:** BMP uses none (uncompressed by default) compression while TIFF uses optional (lzw, zip, jpeg, or none) compression. This affects both file size and the faithfulness of image reproduction. Lossless formats preserve every detail; lossy formats achieve smaller sizes by strategically discarding imperceptible data.
**Color Depth:** BMP supports Up to 32-bit, while TIFF supports Up to 64-bit. Higher color depth means more precise color reproduction, particularly important in professional photography and print workflows.
**Transparency:** BMP does not support transparency, while TIFF does. For web design and graphic design work, transparency is frequently essential.
**File Size:** BMP typically produces very large (1 mb – 100+ mb) files. TIFF produces very large (2 mb – 500+ mb) files. This difference can be significant for web delivery, storage, and bandwidth costs.
To get the best results when converting BMP to TIFF, follow these recommendations:
**Always keep your originals.** Before converting, back up your original BMP files. Conversions — especially to lossy formats — are not perfectly reversible, and you may want the originals for future use.
**Choose the right quality setting.** For lossy TIFF output, a quality setting of 80–90 provides an excellent balance between file size and visual quality for most web use cases. For professional or print use, use 92–95.
**Consider your intended use.** Images for web delivery benefit from aggressive compression to minimize load times. Images for print or archiving should prioritize quality over file size. Images that will be further edited should be kept in lossless formats throughout the editing process.
**Validate the output.** After converting, open a sample of converted files to verify quality meets your expectations before processing an entire batch or deleting originals.
**Web Developers** regularly convert images between formats to optimize website performance, meet platform requirements, and ensure cross-browser compatibility. Converting to TIFF helps ensure images display correctly across all browsers and devices.
**Graphic Designers** working in Figma, Adobe Photoshop, Illustrator, or Sketch convert between formats depending on project requirements. TIFF is commonly used for Professional printing, Medical imaging (DICOM-adjacent).
**Photographers and Content Creators** need different formats for different platforms: JPG for social media and email, WebP for websites, TIFF for professional printing, PNG for graphics and overlays. Converting between formats is a daily workflow task.
**Developers and System Administrators** often automate BMP-to-TIFF conversion as part of image processing pipelines, content management workflows, and media optimization scripts.
