Why convert TIFF to WebP?

TIFF pages are often large and effectively uncompressed, especially scans and archival images. WebP compresses that same page for efficient web delivery, with wider browser support than AVIF.

Is this a lossless conversion?

No. This is not a lossless conversion, and a smaller file is not guaranteed for every source image — though an uncompressed TIFF page usually shrinks substantially.

Does this convert every page of a multi-page TIFF?

No. The WebP encoder only ever sees the first page of the TIFF; pages two and beyond are left out of the conversion.

Are my files uploaded?

No. Conversion runs locally in your browser and does not upload your file to Looty Tools servers.

What is validated before conversion?

The file must actually be a TIFF — the tool checks the byte-order header (little-endian "II*" or big-endian "MM*"), not just the filename or extension, before decoding.

What TIFF to WebP conversion does

Convert a TIFF image to WebP directly in your browser, with adjustable quality for efficient web delivery — a practical way to shrink a large, often uncompressed archival TIFF page down to something a browser can load quickly.

How to convert TIFF to WebP

Choose a TIFF or TIF file.
Adjust WebP quality if needed.
Select Convert & download.
Save the .webp file from your browser downloads.

Why use this conversion

WebP is often used for page assets where current browsers are expected and you want efficient delivery without switching to JPG. Since a TIFF page is typically large and effectively uncompressed, converting to WebP with broad browser compatibility can meaningfully cut load size.

Transparency and output quality

This tool does not flatten onto white. When the browser WebP encoder supports alpha, transparent pixels from the source TIFF page can remain transparent. The quality slider defaults to 90%. Because TIFF pages (as decoded here) are usually large and uncompressed, WebP conversion tends to produce a large size reduction, with broader browser compatibility than AVIF — though complex graphics or high quality settings can narrow that gap.

Privacy and local processing

Processing occurs locally in the browser.
Files are not uploaded to Looty Tools for conversion.
Converted files remain on your device.

Limits and known issues

Input: TIFF (.tif, .tiff) only, up to 25.0 MB and 8,192 px per side.
Encoding requires canvas WebP support. Unsupported browsers show a clear error and do not increment usage.
If the TIFF has multiple pages, only the first is decoded; the remaining pages are not part of the WebP output.
Metadata is not preserved in the downloaded file.
