Free BMP to TIFF converter

Why convert BMP to TIFF?

People convert BMP to TIFF because BMP stores every pixel uncompressed, so the files are enormous for what they actually contain, while TIFF is what print shops, archives and scanning workflows ask for by name.

How to convert BMP to TIFF

1. Choose your BMP file. Drop it on the box above, or tap to browse. You can pick several files at once.
2. Confirm the target is .tiff. It is preselected when your browser can encode it; otherwise the closest available target is chosen. Adjust quality, size or the other options if you want to.
3. Convert and download. Press Convert, then Download. Your file stays on your device the whole time.

What is a .bmp file?

BMP stores pixels uncompressed, which makes files very large and very simple. It survives from early Windows and still appears in older software and some hardware exports; almost any modern format will store the same picture in a fraction of the space.

What is a .tiff file?

TIFF is the lossless format of scanners, print workflows and archives, able to hold multiple pages and very high bit depths. Files are large, and browsers cannot display one, so a TIFF usually has to be converted before it can be shared or put on a web page.

What to expect from this conversion

The target format is lossless, so every pixel of the decoded image is preserved exactly. The result can be larger than the original, which is the normal trade for keeping full quality.

Is it private?

Yes, by design. Every conversion happens inside your own browser using your device’s processor — there is no server that receives your BMP file, so there is nothing for anyone to store, scan or leak. You can confirm it yourself: open your browser’s developer tools, watch the Network tab while you convert, and you will see no upload.

Questions about BMP to TIFF

Is this BMP to TIFF converter free?

Yes, completely. There is no account, no daily limit, no watermark and no premium tier.

Is my BMP file uploaded to a server?

No. The conversion runs inside your own browser using your device's processor. The file is read from your disk, converted in memory and saved back to your disk — nothing is transmitted, so there is nothing for anyone to store.

Can I convert BMP to TIFF online without downloading software?

Yes. This is an online BMP to TIFF converter that runs in your browser, so there is nothing to install and no app to trust with your files. It works the same on a phone.

What happens to the quality?

The target format is lossless, so every pixel of the decoded image is preserved exactly. The result can be larger than the original, which is the normal trade for keeping full quality.

Can I batch convert several BMP files to TIFF at once?

Yes. Select as many files as you like and they are converted one after another in a single tap, with a download for each and a zip of all of them.

Should I keep the original BMP file?

Yes — keep it, converting never touches it. The reason to make a copy in another format is that BMP stores every pixel uncompressed, so the files are enormous for what they actually contain.
