Convert TIFF to WebP — Free, Fast & Private
WebP shrinks a TIFF scan or photo to a web-sized file in one step. The catches are page count, colour mode and app support. Everything runs in your browser — nothing is uploaded.
One page per file
MiniPx converts page 1 of a TIFF and notes when pages were left out.
Colour mode
CMYK pages become RGB, which can shift colours a little. WebP output is 8-bit RGB with optional transparency.
Lossy by default
Smart writes lossy WebP. For scanned text use Gentle, or TIFF to PNG for an exact copy. For maximum compatibility, TIFF to JPG works everywhere.
Scans, print files and cameras
TIFF is lossless and often huge. A WebP copy is the practical version for a website or a gallery, and usually far smaller. For long-term archiving keep the TIFF. The measured table below uses real TIFF files.
Check the WebP against the TIFF before you save
The result card shows the TIFF size, the WebP size and the output dimensions, with a notice when pages were left out. Batches download as a ZIP.
Support
A real WebP is written on every browser, including Safari, through MiniPx's own WebAssembly encoder. WebP displays from Safari 14. More WebP routes are on the WebP converter; TIFF to AVIF goes smaller but is opened by fewer apps.

Measured 2026-10-07 in Chromium 145.0.7632.6 by running this page's converter with its default setting (WebP) on each file. The photos and scans are CC0 or public-domain files from Wikimedia Commons; the TIFF photo is the phone photo halved and saved as an LZW TIFF; the grayscale TIFF is the memo scan saved the way a document scanner writes one (8-bit gray, LZW); the transparent TIFF is the measuring script's app icon saved as an RGBA TIFF. Sizes are shown as the tool shows them (1 KB = 1,024 bytes).
