TIFF to BMP: what changes and when it makes sense
TIFF is a Tagged Image File Format. It is best known for archival quality, high bit depth and CMYK support. The main drawbacks are large files and no display support in most browsers.
BMP is a Bitmap image format. It is best known for a simple structure that legacy programs and embedded systems can read without a decoder library. The main drawbacks are enormous files and no reliable transparency.
TIFF vs BMP at a glance
| Property | TIFF | BMP |
|---|---|---|
| Type | Container format | Raster image |
| Compression | Flexible: uncompressed, lossless (LZW or ZIP) or JPEG-compressed | Usually uncompressed (run-length encoding exists but is rare) |
| Transparency | Full alpha channel with soft edges | None |
| Animation | No | No |
| Colour depth | 8, 16 or 32 bits per channel, with CMYK, layers and multiple pages | 1 to 32 bits per pixel |
| Support | Supported by professional editors, scanners and print workflows. Safari is the only major browser that displays it | Opens in browsers and most desktop software, but almost never used on the web |
| History | Created by Aldus (later Adobe) in 1986 for desktop publishing and scanning. Owned by Adobe since 1994. Remains the professional standard for print, archival imaging and medical imaging. | Created by Microsoft for Windows 1.0 in 1985 as the native bitmap format for the Windows Graphics Device Interface. The "BM" signature has been unchanged since then. Still used in embedded systems and legacy Windows software. |
What actually changes in this conversion
- Both TIFF and BMP are lossless, so the pixels come through unchanged.
- BMP cannot store transparency, so transparent areas are filled with white.
- Expect the BMP file to be far larger than the TIFF source.
- Browser-based conversion works in 8-bit sRGB. Wide-gamut, 10-bit and 16-bit data are reduced. For colour-critical work, keep the original.
- EXIF, GPS and camera data are stripped on every conversion. That is good for privacy, but you lose capture dates.
About TIFF: history and technical details
Created by Aldus (later Adobe) in 1986 for desktop publishing and scanning. Owned by Adobe since 1994. Remains the professional standard for print, archival imaging and medical imaging.
Technical: Tag-based file structure with IFD (Image File Directory) entries. Supports CMYK, Lab, RGB, grayscale, bilevel. 8, 16, 32-bit depth. Multiple pages. Layers via extensions. Compression: none, LZW, ZIP, JPEG, PackBits.
Real-world size: A 300 DPI A4 scan is 25-50 MB as uncompressed TIFF. Same as PNG: 10-20 MB. As JPG at quality 90: 3-8 MB but with loss. Print workflows use TIFF because quality is preserved and CMYK is supported.
Popular tools: Adobe Photoshop, Adobe Illustrator, GIMP, ImageMagick, Capture One, Vuescan, SilverFast.
Alternatives: PNG (8-bit only, no CMYK), JPEG XL (future format), PSD (Photoshop native), PDF (for sharing).
About BMP: what you get
Created by Microsoft for Windows 1.0 in 1985 as the native bitmap format for the Windows Graphics Device Interface. The "BM" signature has been unchanged since then. Still used in embedded systems and legacy Windows software.
Technical: File header 14 bytes (signature, size, reserved, offset) followed by DIB header (40+ bytes). Supports 1, 4, 8, 16, 24, 32-bit pixels. Rows padded to 4-byte boundaries. Pixels can be stored bottom-up or top-down. Optional RLE4/RLE8 rarely used.
Real-world size: A 12-megapixel photo is 36 MB as 24-bit BMP. As JPG it is 2-4 MB (90% smaller). A 1920x1080 screen at 32-bit BMP is 8.3 MB; as PNG 200-600 KB.
Popular tools: Windows Paint, IrfanView, XnView, ImageMagick, GIMP, Adobe Photoshop, embedded dev tools.
Alternatives: PNG (lossless, 5-20x smaller), TGA (game pipelines), TIFF (professional print), JPG (lossy, much smaller).
Browser and software compatibility
TIFF: Supported by professional editors, scanners and print workflows. Safari is the only major browser that displays it. BMP: Opens in browsers and most desktop software, but almost never used on the web.
BMP output opens in browsers and most desktop software, but very few web workflows expect it.
Why people move away from TIFF
- Browsers other than Safari cannot display TIFF, so it is unusable on web pages.
- TIFF files are huge. A single scan can run to hundreds of megabytes.
- Email clients and chat apps often cannot preview TIFF at all.
Why people choose BMP
- Some legacy Windows software, embedded displays and industrial tools only read BMP.
- With no compression there is no decoding step and no compression artefacts.
Common mistakes with TIFF
- Using TIFF for web images — browsers will not display it
- Assuming all TIFFs are lossless — JPEG-compressed TIFF exists
- Ignoring bit depth — a 16-bit TIFF converted to 8-bit loses tonal range
Best practices for keeping quality
- TIFFs often hold 16-bit or CMYK data. Browser conversion works in 8-bit sRGB, so bit depth is reduced and colour can shift. For colour-critical work, use Photoshop or ImageMagick.
- Expect a very large file. Check the upload limit and free disk space before saving.
- Flatten any transparency first. BMP does not reliably carry an alpha channel.
- Resize before converting if the image will be shown small. A 4000 pixel photo displayed at 800 pixels wastes bytes in any format.
- Check the result at 100 percent zoom, especially around text, edges and gradients, before you replace any originals.
- Keep your original files. Conversions to a lossy format cannot be undone.
- When you convert a set of images, use the same quality setting for the whole batch. The converter handles up to 20 files at once.
TIFF to BMP questions
Quick answers about privacy, quality, supported formats, file limits and how BMP works.
Why convert TIFF to BMP?
BMP is lossless. It keeps every pixel exactly. It is the safe choice when you plan to edit, print or need exact pixel data.
Will converting TIFF to BMP lose quality?
No. BMP is lossless, so nothing is thrown away.
Does BMP keep transparency?
No. BMP does not support transparency. Transparent areas will be filled with white.
Are my files uploaded?
Never. Everything runs in your browser. Your files never leave your device. Open DevTools Network tab while processing — you will see no upload request.
Can I convert many files at once?
Yes, up to 20 files at once. Download them individually or all together as a ZIP.
Does the converter strip metadata?
Yes. Browsers do not pass EXIF data through a canvas, so GPS, camera model and dates are removed on every conversion. That is good for privacy.
Is it free?
Yes. No credits, no daily cap, no account, no watermark. The practical limit is your device memory.
Why is BMP so large?
Because it stores raw pixel data with little or no compression. A 12-MP photo as 24-bit BMP is 36 MB, compared to 2-4 MB as JPG. The tradeoff is speed (no decoding needed) and lossless quality.
Your files never leave your device
No upload, no account, no tracking. Everything happens in your browser using the Canvas API and WebAssembly. You can confirm this in your browser's DevTools Network tab while the tool runs — no request carries your file. See why ToolDeck is different.
