TIFF to WebP Converter
Convert TIFF to WebP in your browser. TIFF files usually come from scanners, print and publishing workflows, photo archives and tethered camera capture; WebP is the better fit for images on websites and in apps. You get a lossy WebP at the quality you choose (lossless under More options), keeping transparency. Nothing is uploaded.

Why use Aback Images for tiff to webp
Where the WebP goes next
WebP opens in every current browser, Windows, macOS, Android, and recent Photoshop, GIMP and Affinity.
WebP next to TIFF
A lossy WebP usually comes out far smaller than the TIFF, which stores none, LZW, PackBits, Deflate or JPEG, chosen per file.
The first lossy pass
The TIFF holds 1 to 16 bits per channel, or 32-bit floating point with nothing discarded yet. This conversion is the first lossy encode these pixels see, and hard edges and flat colour show it first.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
TIFF vs WebP
What changes from TIFF to WebP
Encoding: the TIFF uses none, LZW, PackBits, Deflate or JPEG, chosen per file; WebP uses lossy VP8 coding or lossless VP8L, and the download is a lossy WebP at the quality you choose (lossless under More options), keeping transparency.
Bit depth: 1 to 16 bits per channel, or 32-bit floating point in the TIFF; WebP allows 8 bits per channel, and the WebP written here has 8 bits per channel. 16-bit and floating-point TIFFs are reduced to 8 bits per channel.
Colour: RGB, CMYK, Lab, greyscale or palette, often with an ICC profile in the TIFF; WebP supports RGB; lossy WebP stores colour at half resolution (4:2:0), written here as 8-bit sRGB.
Transparency: the TIFF stores it as an extra sample declared in the ExtraSamples tag; the WebP keeps it as a separate alpha plane, available in lossy as well as lossless files.
Other images: the TIFF can hold several pages, each in its own image file directory; only the main image is converted.
Metadata: the TIFF can carry EXIF, XMP, IPTC and ICC, all stored as tags; WebP can carry EXIF, XMP and ICC chunks, but nothing is copied across.
About TIFF
TIFF is the professional archive and print format. It can hold multiple pages, high bit depths and lossless data, and is common in scanning, publishing and GIS.
A TIFF begins with 'II' or 'MM' for the byte order and the number 42, then an offset to the first image file directory (IFD): a table of tags giving the size, compression, colour model and the location of the strips or tiles of pixels. Each further page is another IFD.
TIFF files usually come from scanners, print and publishing workflows, photo archives and tethered camera capture.
About WebP
WebP is Google's web image format. It supports lossy and lossless compression, transparency and animation, and is typically 25 to 35 percent smaller than JPEG at the same visual quality.
A WebP is a RIFF file: 'RIFF', a length, 'WEBP', then chunks. A simple lossy file is one VP8 chunk and a lossless one is VP8L; the extended VP8X header announces alpha, animation, ICC, EXIF or XMP chunks.
When converting TIFF to WebP makes sense
WebP is the better choice for images on websites and in apps, while TIFF suits printing, scanning and archival masters.
WebP strengths: 25-35% smaller than JPEG; Transparency and animation in one format; Supported by every modern browser. Drawbacks to weigh: Some older desktop apps and photo printers cannot open it; Max 16383 px per side.
Limitations
- Only the first page of a multi-page TIFF is converted; split the file first if you need every page.
- CMYK TIFFs from print workflows are converted to RGB, which changes how a print shop's colours are described.
- A few older desktop apps, print services and upload forms still reject WebP; keep a JPG or PNG copy for those.
- WebP images are limited to 16383 pixels on each side.

Frequently asked questions
Does converting TIFF to WebP lose quality?
WebP is lossy, so detail the eye barely notices is discarded to save space. 16-bit and floating-point TIFFs are reduced to 8 bits per channel. Not carried over: any several pages.
Is transparency kept in the WebP?
Yes. TIFF stores it as an extra sample declared in the ExtraSamples tag, and the WebP is written with an alpha channel, so transparent areas stay transparent.
What quality should I choose for WebP?
80 to 85 is visually close to the original for most photos. Go lower for thumbnails, or switch on Lossless under More options for screenshots and graphics.
Which apps open WebP files?
Every current browser, Windows, macOS, Android, and recent Photoshop, GIMP and Affinity.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
