Why convert BMP to TIFF?
BMP is excellent for legacy Windows software, embedded devices and raw pixel workflows, but it has some limitations:
- Huge file sizes
- Poor web support
- No transparency in common variants
Converting to TIFF gives you:
- Archival, lossless quality
- Multi-page support
- Preferred by printers and scanners

What are BMP and TIFF files?
BMP (.bmp)
BMP is an old uncompressed bitmap format from Microsoft Windows. It stores raw pixel data, so quality is perfect but files are very large.
TIFF (.tif, .tiff)
TIFF is a high-quality format used for printing, scanning and archiving. It supports layers and multiple pages, which makes it popular with scanners, publishers and photographers.

Private by design: how this converter works
Unlike typical online converters that upload your file to a remote server, this BMP to TIFF converter processes everything on your own device using the HTML5 Canvas API and native image decoders built into your browser. Your file is read into browser memory, converted, and offered back as a download — it is never sent to us.
- No upload wait — conversion starts instantly, even on slow mobile data.
- Private — safe for NID copies, certificates, bank statements and personal photos.
- No limits — no daily quota, no queue and no watermark.
- Offline-ready — once loaded, many tools keep working without internet.
