Why convert TIFF to AVIF?

TIFF and AVIF serve different purposes. Converting between them lets you use whichever format works best for your situation.

What is a TIFF file?

Tagged Image File Format: TIFF is a high-quality image format used in publishing, photography, and scanning. It supports lossless compression and stores a lot of metadata, which makes files large but preserves every detail.

Created by: Aldus Corporation (now Adobe), first released in 1986

Used for: Print publishing, professional photography, document scanning, archival storage

Technical details: Supports lossless and lossy compression, multiple layers, 16-bit color depth, and extensive metadata. Files can be very large.

Compatibility: Supported by professional image editors and publishing software. Not natively displayed by most web browsers.

What is a AVIF file?

AV1 Image File Format: AVIF is a newer image format based on the AV1 video codec. It compresses images more efficiently than JPEG or WebP, producing smaller files at the same quality. Browser support has been catching up quickly.

Created by: Alliance for Open Media, first released in 2019

Used for: Web images where file size is critical, high-quality photo compression

Technical details: Based on AV1 video codec. Supports lossy and lossless compression, HDR, wide color gamut, and transparency. Typically 20-50% smaller than JPEG at similar quality.

Compatibility: Supported in Chrome, Firefox, Safari (since 16.4), and Edge. Some older browsers and image editors may not support it yet.
