Does it convert every TIFF page?
No. Only the first page of each TIFF is decoded and converted to WebP.

How to convert TIFF to WebP
01
Set WebP quality
Choose a value from 60 to 95 before adding files; the default is 85.
02
Add TIFF or TIF files
Select one or more files. Each accepted file starts converting immediately.
03
Wait for local processing
The first TIFF page is decoded to RGBA pixels and encoded as WebP.
04
Download the results
Save one WebP at a time or package multiple completed files in a ZIP.
What the converter actually does
First page only
Extra pages in a multi-page TIFF are not converted.
Lossy WebP output
Decoded RGBA pixels are encoded at the selected quality.
Quality 60–95
The default is 85 and is read when conversion begins.
Batch workflow
Each accepted TIFF becomes its own result.
Individual or ZIP
Download one result or bundle multiple completed files.
Metadata is not copied
TIFF tags, profiles and higher bit depth are not transferred.
Common TIFF-to-WebP mistakes
Expecting every TIFF page
Only the first page is processed.
Changing quality after adding files
Existing results are not automatically re-encoded.
Calling the conversion lossless
The WebP encoder uses lossy quality settings.
Assuming a smaller result
A source already compressed efficiently can produce a larger WebP.
Adding too many large scans
Batch work can exhaust browser memory.
Expecting TIFF metadata
The output is encoded from decoded pixels.

Frequently asked questions
What WebP quality is used?
Quality starts at 85 and ranges from 60 through 95. Set it before adding files because conversion begins immediately.
Does changing quality re-encode results?
No. Completed files keep the quality used when their conversion started.
Is the WebP lossless?
No. This component uses the WebP encoder with the selected lossy quality value.
Can WebP retain transparency?
The decoder supplies RGBA pixels to the WebP encoder, but exact alpha results depend on the TIFF variant and its transparency data.
Will WebP always be smaller?
No. Output size depends on source compression, pixel content and quality, so the WebP can be smaller or larger.
Why can conversion fail?
Unsupported or corrupt TIFF data, very large dimensions and limited browser memory can prevent decoding or encoding.
Are files uploaded?
No. TIFF decoding and WebP WebAssembly encoding run locally in your browser.
