What is TIFF and why convert BMP to TIFF?

TIFF (Tagged Image File Format) is a lossless image format used in professional photography, print production, and archiving. BMP files are also uncompressed, but TIFF adds wider software support, metadata capabilities, and is the standard format for professional print and post-production workflows. Converting BMP to TIFF gives you a file that opens everywhere professional imaging software is used.

Can I crop the BMP image before converting to TIFF?

Yes — the tool provides an interactive crop overlay on the source image. Drag the corner and edge handles to define exactly which portion of the BMP you want in the output TIFF. Click Preview Crop to see the result in a pop-up window before downloading.

Does my image get uploaded to a server?

No. All processing — loading, cropping, and TIFF encoding — happens entirely in your browser using JavaScript and the HTML5 Canvas API. Your image never leaves your device.

How does the tool load BMP files?

The tool uses URL.createObjectURL combined with img.decode() to load BMP files reliably. The img.decode() promise resolves only after the image is fully decoded and ready to paint, ensuring the canvas always receives complete pixel data before the crop overlay is drawn.

What is the maximum image size supported?

The tool is limited by your browser's available memory. BMP files can be very large due to their uncompressed nature — a 24 MP BMP can be 70+ MB. In practice, BMP files up to 30–50 MP convert reliably on modern desktop browsers. Very large images on mobile devices may be slower due to memory constraints.

How do I reset and convert a different image?

Click the Start Over button that appears after loading an image. This clears the current file and resets the crop area so you can load a new BMP.

BMP to TIFF Crop Converter

Load a BMP, drag the crop handles to define exactly the area you need, preview the result, then download a lossless TIFF. Everything runs in your browser — your image never leaves your device.

What This Tool Does

This tool loads a BMP image directly in your browser, presents an interactive crop overlay with draggable handles, and converts the selected area to a lossless TIFF file. No server upload is required. The full workflow — loading, cropping, encoding — runs entirely in client-side JavaScript using the HTML5 Canvas API. BMP files are decoded using URL.createObjectURL combined with img.decode(), which resolves only after the image is fully decoded and ready to paint, ensuring the canvas always receives complete pixel data before the crop overlay is drawn. The output is an uncompressed 24-bit RGB TIFF, the format expected by professional print workflows, photo editing software, and archival systems.

Who This Is For

Designers and photographers who need to deliver a specific cropped region of a BMP file as a TIFF for print production
Archivists extracting a portion of a scanned BMP document for lossless preservation in TIFF format
Developers converting legacy BMP assets to TIFF for use in professional imaging pipelines
Anyone who needs to trim and convert a BMP to TIFF without installing Photoshop or GIMP

Frequently Asked Questions

What is TIFF and why is it used in professional workflows?▼

TIFF (Tagged Image File Format) stores image data without lossy compression. Unlike BMP, TIFF is universally supported by professional print systems, prepress software, RAW processors, and archival systems. It also supports higher bit depths, ICC color profiles, and metadata embedding that BMP does not provide.

How precise is the crop tool?▼

The crop operates at native pixel accuracy on the original BMP dimensions. The canvas is scaled to fit your screen for display, but the actual crop coordinates are mapped back to the full-resolution image before the TIFF is generated. You get a TIFF at the exact pixel dimensions shown in the crop dimensions badge.

Can I move the crop selection after setting it?▼

Yes — click and drag inside the crop rectangle (away from the handles) to reposition it anywhere within the image. Handles resize; the interior pans.

Does the output TIFF use compression?▼

The output is an uncompressed TIFF for maximum compatibility. This means the file size will be similar to the source BMP but opens in every application that supports TIFF without any codec requirement.

What browsers are supported?▼

All modern browsers — Chrome, Firefox, Edge, Safari (desktop and mobile). The tool uses standard HTML5 Canvas and Blob APIs that have been universally supported since 2015.

Is there a file size limit?▼

There is no server-imposed limit because no upload occurs. The practical limit is your browser's available RAM. BMP files can be very large due to their uncompressed nature. Most modern desktops handle BMPs up to 50 MP comfortably. Very large files on memory-constrained mobile devices may be slower to process.
