Should you convert BMP to TIFF?

A safe conversion when TIFF is what you need: both BMP and TIFF keep every pixel, so the picture itself doesn’t change.

Bear in mind TIFF is has patchy support: it works in photo editors, macOS Preview and Windows Photos, but not Chrome, Firefox or most upload forms.

BMP is an uncompressed grid of pixels; TIFF is a high-fidelity format used by scanners, printers and archives. Use TIFF when a printer, publisher or archive asks for it, or for master copies of scans.

How to convert BMP to TIFF

01
Add your BMP

Drop your BMP image onto the box, or click to choose it. It is read from your disk and stays there.
02
Check the settings

The output is already set to TIFF. Change the quality if you want to; the defaults suit most files.
03
Save the TIFF

Press convert and save the TIFF. Several files come back together as a ZIP.

What changes when BMP becomes TIFF

Nothing is discarded

BMP and TIFF both keep every pixel, so the picture survives the move intact. You can convert back and forth as often as you like without it degrading.

Expect a smaller file

TIFF usually stores the same content in less space than BMP. BMP: A 12-megapixel image is about 36 MB. TIFF: A scanned A4 page can be 20–50 MB.

This page is put together from our notes on each format, choosing only what is true of BMP and TIFF, so every pairing states the same facts the same way. How these pages are made.

Why it doesn’t upload

Changing a picture’s format is work your browser already knows how to do. Sending your photos to a server first only adds waiting and risk, so nothing is sent.

Worth knowing

About the BMP. BMP looks like a safe “raw” choice, but a single photo can run to tens of megabytes and most sites refuse it.
About the TIFF. Multi-page TIFFs from scanners look like one picture in some viewers, so pages go unnoticed when converting.
DDS, PSD, EXR, XWD and JPEG 2000 are read by the FFmpeg engine, a one-time 31 MB download.
