Why convert TIFF to WebP
TIFF to WebP: reduce file size 95% without sacrificing visual quality
Digitization for the web
Publish TIFF-scanned documents and photos on the web with files 10-20 times lighter.
100% private
Your TIFF is processed in your browser. Never uploaded to any server, regardless of file size.
Compatible with all CMS
CMS platforms do not accept TIFF for web publishing. WebP works in WordPress, Shopify, and all modern CMS.
No size limits
Process large TIFFs from professional scanners directly in the browser without server queues.
How it works
Three steps, no hassle
Upload your TIFF file
Drag and drop or select your .tiff or .tif file. Accepts uncompressed TIFF, LZW, PackBits, or ZIP-compressed TIFF exported from scanners, Photoshop, or RAW cameras.
Adjust WebP quality
Use the quality slider to control the size-to-quality ratio. For web files, 80-85% is the optimal point.
Download the WebP
Get a WebP up to 20 times lighter than the original TIFF, ready to publish on the web, send by email, or upload to a CMS.
FAQ
Got questions?
TIFF (Tagged Image File Format) was developed by Aldus Corporation in 1986 and acquired by Adobe Systems in 1994. The current specification is TIFF 6.0, published in June 1992. TIFF is the industry standard for high-quality image files because it is flexible: it supports multiple color modes (RGB, CMYK, LAB, grayscale), bit depths up to 32 bits per channel, multiple layers and pages, and optional compression. An uncompressed TIFF of a 24-megapixel photo is approximately 70 MB. Even with LZW compression (lossless), the file remains 20-40 MB. Professional document scanners (such as Fujitsu ScanSnap or Epson Perfection models) save to TIFF by default to preserve maximum fidelity. This makes TIFF completely unsuitable for the web without conversion.
The size reduction is significant: an uncompressed 70 MB TIFF typically becomes a 2-5 MB WebP at 85% quality — a 93-97% reduction. A 15 MB LZW TIFF produces a 1-3 MB WebP. The exact ratio depends on content: photographs with smooth gradients compress better than documents with sharp text or images with fine detail. For scanned documents (text on paper), also consider PDF/A or PNG if you need perfectly sharp text, as WebP with aggressive compression can produce artifacts at text edges.
TIFF supports embedded ICC (International Color Consortium) profiles, used in professional print workflows to ensure exact color reproduction across different devices. The browser converter uses the HTML5 canvas element, which works in sRGB color space (the standard web color space, defined by IEC specification 61966-2-1 from 1999). Wide-gamut ICC profiles (AdobeRGB, ProPhoto RGB, CMYK) are approximately converted to sRGB during rasterization. For print workflows where exact color management is critical, use professional tools like Photoshop or GIMP with full ICC profile support.
Multi-page TIFFs are a common use case for scanned documents — each page of the document is a 'page' of the TIFF. The browser Canvas API can only access the first page/frame of a multi-page TIFF. To convert all pages of a scanned TIFF document to WebP, you would need to process the file with a server-side tool like ImageMagick (command: magick document.tiff -quality 85 page_%d.webp) or Pillow in Python.
Document and photography scanners generate TIFF as the master file format because it is the only widely supported format that combines: lossless (or minimal-loss LZW), high color depths (16 bits per channel for archival photography), CMYK support for print workflows, and universal compatibility with editing software (Photoshop, GIMP, Affinity Photo, Lightroom). TIFF files are the standard in cultural heritage digitization (museums, libraries, historical archives) according to the FADGI (Federal Agencies Digital Guidelines Initiative) specification from the U.S. government. For publishing these digitizations on the web, conversion to WebP is the optimal path.
Yes. TIFF supports both associated and unassociated alpha channels (premultiplied and straight). If your TIFF has transparency (common in Photoshop compositions with layers exported as a flat TIFF with alpha), the converter preserves the alpha channel in the resulting WebP. This is useful for high-quality graphic elements — product cutouts, advertising composites — that you need to publish on the web while maintaining transparent backgrounds.
Convert TIFF to WebP: scanner archive digitization and web optimization
TIFF (Tagged Image File Format) was originally developed by Aldus Corporation in 1986 and acquired by Adobe Systems in 1994, which has maintained the specification since then. The current version, TIFF 6.0 (published June 1992), defines an extraordinarily flexible format: it supports lossless compression (LZW, from Terry Welch's 1984 specification, and ZIP/Deflate), lossy compression (embedded JPEG), depths up to 32 bits per channel, RGB, CMYK, LAB, and grayscale color spaces, embedded ICC profiles, multiple pages in a single file, and extensible tags. This flexibility makes TIFF the standard format in professional image workflows: production scanners (Fujitsu, Epson, Canon), editing software (Adobe Photoshop, which has supported TIFF since its first version in 1990), medium-format digital cameras, and cultural heritage digitization projects following the FADGI (Federal Agencies Digital Guidelines Initiative) specifications from the U.S. government and the European Metamorfoze standard. The problem is that TIFF has no place on the web: uncompressed files from 50-megapixel cameras exceed 150 MB, browsers do not support it natively for HTML rendering, and CMS platforms systematically reject it.
WebP (Google specification, 2010, based on the VP8 codec from On2 Technologies acquired by Google in 2009) is the optimal destination format for publishing web content originally in TIFF. The size reduction is dramatic: an uncompressed 70 MB TIFF converts to a 2-5 MB WebP at 85% quality — a 93-97% reduction with imperceptible visual difference on screen. For archival digitization projects — museums publishing their collections online, libraries digitizing historical holdings, photographic archives creating web galleries — this compression makes publishing entire collections viable without prohibitive bandwidth or storage costs. The cultural heritage digitization standard for master files is uncompressed TIFF at 400-600 DPI; web derivative files are generated in lighter formats. WebP at 80-85% quality provides the best quality-to-size ratio for these web derivatives.
TIFF-to-WebP conversion in the browser uses the HTML5 Canvas API: the TIFF is loaded as an ImageBitmap (supported in Chrome 50+, Firefox 42+, Safari 15+) and rendered onto a canvas, which is then exported to WebP via the toBlob() method. Native browser support for TIFF is limited — Chrome and Firefox support basic TIFF, Safari is more comprehensive — but for most scanner TIFF files (uncompressed or LZW, 8 bits per channel, RGB or grayscale) support is sufficient. For TIFF with advanced features (16 bits per channel, CMYK, wide-gamut ICC profiles, multiple pages), the server-side reference tool is ImageMagick (open-source project initiated by John Cristy in 1987, now supporting over 200 formats) with commands like magick input.tiff -quality 85 output.webp. For large-scale digitization projects, the combination of VIPS (libvips, the high-efficiency image processing library from Birkbeck College) with the Node.js binding sharp is the industry standard for mass conversion pipelines.
