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 an AVIF file. No server upload is required. The full workflow — loading, cropping, encoding — runs entirely in client-side JavaScript using the HTML5 Canvas API. TIFF 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 AVIF image, a modern format offering superior compression and quality over legacy formats like JPEG and PNG.
Who This Is For

- Photographers reducing archive TIFF files to web-optimized AVIF for online portfolios
- Designers cropping a specific region of a TIFF and delivering it as a modern AVIF file
- Anyone who needs to trim and convert a TIFF to AVIF without installing Photoshop or GIMP
