Convert TIFF to AVIF

How it works

The server opens the TIFF and decodes its first image into pixels. TIFF can use many compression methods, color models, and page structures, so the browser is not asked to interpret that production-oriented container. The decoded first page is passed to an AVIF encoder, which uses a lossy quality setting to find a smaller representation. The result is a new AVIF file, not a TIFF renamed for a browser.

AVIF is valuable here because it is built for modern image delivery. It can describe photographic gradients and texture with far fewer bytes than a typical uncompressed or lightly compressed TIFF. That advantage depends on accepting a quality tradeoff. At normal display size the loss may be hard to see, but a scan with small lettering or technical lines needs a closer inspection than a landscape photograph. Compare the actual content, not only the byte count.

Why this helps web and storage workflows

Browsers and content systems increasingly understand modern web codecs, while TIFF is still associated with scanners, print production, and desktop imaging. A TIFF can be excellent as a master and still be the wrong file to send on every page view. An AVIF derivative reduces network transfer and storage for a site that has confirmed its browser and editor support. Keep a fallback format when the audience includes older clients or a CMS does not accept AVIF.

The largest savings often come from dimensions rather than from codec choice. A scan made for a printed page may contain several times more pixels than the web layout can show. Resize from the TIFF to the maximum useful content width before encoding. This avoids spending bandwidth on pixels that will be discarded by the browser's layout, and it leaves the full-resolution source available for a later print export.

The first-page and quality boundaries

TIFF is allowed to contain multiple pages, which is common for fax bundles and office scanners. This single-image route selects page one because an AVIF output has one image slot. Do not label that result as the complete report. Generate a numbered AVIF per page for a viewer, or choose a document container when preserving the page set is the actual requirement.

Finally, avoid using the AVIF as the only copy of a scan. Lossy encoding is useful for delivery and often excellent for photographs, but it is not an archival policy. Keep the TIFF, inspect fine details at the destination size, and regenerate a new AVIF from the master when quality, dimensions, or the page selection needs to change.
