Is my image uploaded to a server?

No. All conversion happens entirely in your browser using the Canvas API. Your file never leaves your device.

What quality setting should I use?

For most web use cases, 80–90 provides an excellent balance of quality and file size. Use 100 for lossless-equivalent output, or go lower for maximum compression.

Does this support multi-page TIFF files?

The built-in TIFF decoder reads the first page for conversion. For exporting every page, use a dedicated multi-page TIFF tool.

Why is WebP better than TIFF for the web?

TIFF is an archival format with very large file sizes. WebP is optimized for the web, offering lossy and lossless compression, transparency support, and 25–35% smaller files than comparable JPEG or PNG.

What browsers support WebP conversion?

All modern browsers (Chrome, Edge, Firefox 96+, Safari 14+) support WebP encoding via the Canvas API. If your browser does not support it, a warning is shown.

Are there file size limits?

There is no hard server-side limit since processing is local. Very large TIFF files (above 100 MB) may be slow depending on your device memory and CPU.

Summary

This tool converts TIFF images to WebP format directly in your browser using the Canvas API. No files are uploaded to any server — all processing happens locally on your device. WebP typically produces 80–95% smaller files than an uncompressed TIFF — and around 25–35% smaller than a comparable JPEG or PNG — while maintaining excellent visual quality, making it ideal for web publishing.

How it works

Click "Choose TIFF File" and select a .tiff or .tif file from your device.
The image is decoded by your browser and drawn onto an invisible canvas.
Adjust the quality slider (1–100) to balance file size vs. image fidelity.
The canvas exports the image data as WebP using the browser's built-in encoder.
A real-time preview appears alongside file size estimates for both formats.
Click "Download WebP" to save the converted file to your device.

Use cases

Reduce large TIFF scan files before uploading them to a website.
Convert design exports from Photoshop or GIMP to a web-ready format.
Batch-prepare product photography from TIFF originals for e-commerce.
Shrink archival TIFF images for sharing without losing noticeable quality.
Convert medical or GIS imagery stored as TIFF for web visualization.
Quickly compare visual quality at different WebP compression levels.
