TIFF to WebP Crop Converter

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

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 WebP file. No server upload is required. The full workflow — loading, cropping, and WebP 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. A quality slider lets you control the output compression ratio before downloading. Unlike JPEG, WebP fully preserves any alpha channel transparency in your source image.

Who This Is For

  • Web developers optimising TIFF assets to compact WebP images for faster page loads
  • Designers exporting a specific cropped region of a TIFF to WebP for use in modern web interfaces
  • Photographers reducing large TIFF archives to web-deliverable WebP files for online galleries
  • Anyone who needs to trim and convert a TIFF to WebP without installing Photoshop or GIMP

Frequently Asked Questions

How does WebP compare to JPEG and PNG for web use?
WebP is typically 25–35% smaller than JPEG at equivalent visual quality, and 20–30% smaller than PNG for lossless content. Unlike JPEG, it also supports transparency. This makes WebP the best all-round format for web images when file size and quality are both priorities.
What quality setting should I use?
The default of 85% is ideal for most photographic web content — visually excellent while significantly smaller than JPEG. Use 90–95% for high-fidelity thumbnails or product images where detail is critical. Use 70–80% for social media previews or thumbnails where maximum compression matters most.
Does transparency carry through from TIFF to WebP?
Yes. WebP supports a full alpha channel in both lossy and lossless modes. Any transparent or semi-transparent pixels in your TIFF source are preserved in the WebP output — unlike JPEG, which requires flattening transparency to a solid colour.
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 crop coordinates are mapped back to the full-resolution image before the WebP is generated.
What browsers are supported?
All modern browsers — Chrome, Firefox, Edge, Safari (desktop and mobile). WebP encoding via canvas.toBlob is supported in Chrome 32+, Firefox 96+, and Safari 14+. The tool uses standard HTML5 Canvas and Blob APIs.
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.
