WebP to TIFF Crop Converter
Load a WebP, drag the crop handles to define exactly the area you need, preview the result, then download a lossless uncompressed TIFF. Every pixel is preserved exactly. Transparency is retained. Everything runs in your browser — your image never leaves your device.

What This Tool Does
This tool loads a WebP image directly in your browser, presents an interactive crop overlay with draggable handles, and converts the selected area to a TIFF file. No server upload is required. The workflow runs entirely in client-side JavaScript using the HTML5 Canvas API. The cropped pixel data is read via ctx.getImageData() and written into a hand-constructed TIFF binary: a little-endian baseline TIFF with all required IFD tags (ImageWidth, ImageLength, BitsPerSample, Compression=1, PhotometricInterpretation, StripOffsets, SamplesPerPixel=4, RowsPerStrip, StripByteCounts, ExtraSamples for alpha, and SampleFormat). The result is a valid uncompressed 32-bit RGBA TIFF readable by Photoshop, GIMP, LibTIFF, and any TIFF-capable application.
Who This Is For
- Photographers and retouchers who need a lossless TIFF crop from a WebP source for editing in Photoshop or Lightroom
- Print designers who require an uncompressed TIFF for press-ready workflows in InDesign or QuarkXPress
- Archivists converting WebP content to a long-term preservation format
- Anyone who needs to trim and convert a WebP to TIFF without installing desktop software
