Is my file uploaded to a server?

No. The entire conversion runs inside your browser using JavaScript and the HTML5 Canvas API. Your file never leaves your device.

What types of TIFF files are supported?

Standard grayscale, RGB, and RGBA TIFF files are supported, including LZW-compressed and uncompressed variants. CMYK and multi-sample exotic formats may not render correctly in all browsers.

What BMP format is produced?

The output is a standard 24-bit uncompressed BMP (DIB), compatible with Windows Paint, Photoshop, GIMP, and most imaging libraries.

Can I convert multi-page TIFF files?

Yes. Each page is shown as a separate preview and can be downloaded as its own BMP file.

Why is the file size larger after conversion?

BMP is an uncompressed format. A TIFF compressed with LZW will produce a larger BMP because all pixel data is stored without compression.

Is there a file size limit?

There is no hard server limit since conversion is client-side. Very large files (over ~50 MB) may be slow depending on your device memory and CPU.

Summary

This tool converts TIFF (.tif / .tiff) images to BMP (Bitmap) format entirely within your browser using the HTML5 Canvas API. No file is ever sent to a server — conversion happens locally on your device. The resulting BMP is a standard 24-bit uncompressed bitmap ready for use in any graphics application.

How it works

Select or drag a TIFF file onto the upload area.
The browser decodes the TIFF using UTIF.js into raw pixel data.
The pixel data is painted onto an HTML5 Canvas element.
The Canvas is read back and the raw pixel data is encoded into a 24-bit BMP binary.
A download link is generated so you can save the BMP file immediately.

Use cases

Prepare scanned documents for software that only accepts BMP.
Convert fax images (often TIFF) to BMP for legacy Windows apps.
Strip TIFF metadata when moving images between workflows.
Quickly check a TIFF image without installing a desktop viewer.
Convert multi-page TIFF — each page is exported as a separate BMP.
Work offline: after page load no network is required.
