Is my image uploaded to a server?

No. The entire conversion runs inside your browser using the HTML5 Canvas API. Your image never leaves your device.

Is the output a true TIFF file?

Browsers cannot write the native TIFF binary format. The downloaded file contains PNG-compressed pixel data and uses a .tiff extension. For strict TIFF compliance with LZW compression, multi-page support, or EXIF metadata, use a desktop tool such as GIMP or ImageMagick.

Will the image quality be affected?

At 100% scale the output is a lossless PNG-inside-TIFF copy of your original WebP. Reducing the scale slider resamples the image to smaller dimensions.

Does WebP transparency carry over?

Yes. WebP images with transparent backgrounds are preserved in the output because the PNG encoding inside the TIFF container supports full alpha transparency.

What browsers are supported?

Any modern browser that supports the HTML5 Canvas API and native WebP decoding — Chrome, Firefox, Edge, and Safari 14+.

Summary

Upload a WebP image and download it as a .tiff file — converted entirely inside your browser with no server upload.

How it works

Select or drag a WebP image onto the upload area.
Optionally adjust the output scale (50%–100%) to reduce file dimensions.
The tool draws your image onto an HTML5 Canvas element inside your browser.
The canvas exports PNG-compressed pixel data, which is saved with a .tiff extension.
A preview of the converted image is shown with dimension and size details.
Click "Download TIFF" to save the file to your device.

Use cases

Quickly rename and re-package a WebP image for workflows that expect a .tiff extension.
Prepare images for print or archival pipelines that accept .tiff files.
Convert WebP photos for design software that loads TIFF by extension.
Process images privately without uploading to a third-party service.
Scale down a large WebP image while saving it as a .tiff for storage.
Generate a TIFF-named file for software that reads PNG data inside TIFF containers.
