About BMP and TIFF
BMP .bmp
Microsoft's plain bitmap. It generally stores pixels with no compression at all, which makes it simple to read and very large on disk.
Good for
- Dead simple — every pixel stored literally
- No compression artefacts of any kind
- Reliably readable by old Windows software
Trade-offs
- Enormous files, often ten times a PNG of the same image
- Effectively unusable on the web
- Transparency support is inconsistent between readers
image/bmp
TIFF .tiff
A flexible container used wherever image fidelity matters more than file size — scanning, publishing and archives. A single TIFF can hold multiple pages.
Good for
- Lossless storage suitable for archival masters
- Multi-page, which suits scanned documents
- Standard in print, publishing and document capture
Trade-offs
- Very large files
- Poor support in browsers — effectively unusable on the web
- So flexible that not every reader supports every variant

BMP and TIFF side by side
| BMP | TIFF | |
|---|---|---|
| Compression | Uncompressed | Lossless (usually) |
| Transparency | Limited — 32-bit variants only | Yes |
| Animation | No | No — but multi-page |
| Typically used for | Legacy Windows software, intermediate working files | Scanning, print production, archival masters |
What changes when you convert BMP to TIFF
How the TIFF is written
Our default is quality 90 with LZW compression, which every print and scanning tool reads. The quality control on the converter moves this if you need to — the default aims to be indistinguishable from the source at a sensible file size, rather than to win a compression benchmark.
Expect a dramatic drop in size
A BMP stores every pixel literally, with no compression at all — which is why they are so large. TIFF compresses, so the same image commonly lands somewhere between a tenth and a half of the size it started at. Nothing about the picture changes to achieve that: the file was simply storing its pixels in the least efficient way available.
Nothing is lost in this step
Both BMP and TIFF store every pixel exactly, so this conversion changes the container rather than the content. What changes is file size and what will open it — convert freely, and as often as you like, without degrading anything.

Where your transparent background went
Transparency is the property most often lost silently in a conversion — the file looks perfect until it lands on a coloured background and grows a white rectangle.
