What is GIF and why convert TIFF to GIF?

GIF (Graphics Interchange Format) is a widely supported image format limited to 256 colors, making it ideal for simple graphics, logos, and illustrations. TIFF files are large professional-grade images. Converting a cropped TIFF region to GIF produces a compact, universally compatible file suitable for web use, email, and legacy systems that require GIF format.

Can I crop the TIFF image before converting to GIF?

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 TIFF you want in the output GIF. Click Preview Crop to see the result before downloading.

Does my image get uploaded to a server?

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

How does the tool handle GIF's 256-color limitation?

GIF supports a maximum of 256 colors. The tool uses the browser's built-in canvas.toBlob('image/gif') where supported, or encodes a GIF using an optimized median-cut color quantization algorithm to reduce the cropped image to the 256-color palette with minimal visible quality loss.

What is the maximum image size supported?

The tool is limited by your browser's available memory. TIFF files can be very large. In practice, TIFF 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 TIFF.

What This Tool Does

This tool loads a TIFF image directly in your browser, presents an interactive crop overlay with draggable handles, and converts the selected area to a GIF file. No server upload is required. The full workflow — loading, cropping, and GIF encoding — runs entirely in client-side JavaScript using the HTML5 Canvas API. TIFF files are decoded using URL.createObjectURL combined with img.decode(), ensuring the canvas always receives complete pixel data before the crop overlay is drawn. The output is a GIF encoded using a median-cut color quantization algorithm to reduce the image to GIF's 256-color palette while preserving maximum visual quality.

Who This Is For

Web designers who need to deliver a specific region of a TIFF as a small GIF for email or legacy web pages
Developers exporting TIFF assets to GIF for systems or platforms that only support the GIF format
Anyone who needs to extract and convert a portion of a TIFF to GIF without installing dedicated software
Content creators who want a quick, privacy-respecting crop-and-convert tool that needs no account or upload

Frequently Asked Questions

Why does GIF look different from the original TIFF?▼

GIF supports only 256 colors, while TIFF can store millions. For photographic images, this color reduction produces visible banding or dithering. GIF looks best with flat-color graphics, logos, illustrations, and screenshots with limited color ranges. For photos, consider using AVIF, WebP, or JPEG instead.

How precise is the crop tool?▼

The crop operates at native pixel accuracy on the original TIFF 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 GIF is generated. You get a GIF 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 GIF support transparency?▼

GIF supports binary (1-bit) transparency — pixels are either fully transparent or fully opaque. There is no partial transparency (alpha blending). If your TIFF has semi-transparent pixels, they will be converted to either fully transparent or fully opaque in the GIF output.

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. TIFF files can be very large. Most modern desktops handle TIFFs up to 50 MP comfortably.
