About the output format

When JPG is the right output

JPG is the default format for photographs — 24-bit colour, lossy compression tuned for continuous-tone imagery, universally supported. Ubiquity is its main strength: government portals, e-commerce marketplaces, print labs, and CMS uploaders that don't say what format they want will accept JPG. The trade-offs: no transparency, no lossless option, compression artefacts around sharp edges (text, logos). Use JPG when the source is a photograph and the destination doesn't require a transparent background.

AVIF to JPG: next-gen to universal

AVIF uses the AV1 codec — a royalty-free video codec that achieves 50% better compression than JPG and 20% better than WebP. The decoder unpacks AV1's prediction-based compressed data into raw pixels, then re-encodes with JPG's DCT algorithm. The resulting JPG is typically 2-4× larger than the AVIF at equivalent visual quality. AVIF supports HDR, wide color gamut, and alpha transparency — all of which are tone-mapped or flattened during JPG conversion.

When to convert AVIF to JPG

Convert AVIF to JPG when you need to open the image in software that doesn't support AVIF yet (Photoshop versions before 2023, many image viewers on Windows 10 without the AV1 extension), share via email or messaging, or upload to platforms that reject AVIF.

About the AVIF Format

AVIF (AV1 Image File Format) is a next-generation image format based on the open-source AV1 video codec, standardized in 2019 by the Alliance for Open Media. It delivers exceptional compression efficiency — typically 20-30% better than WebP and up to 50% better than JPEG at equivalent visual quality. AVIF supports both lossy and lossless compression, making it one of the most versatile modern image formats available.

AVIF is designed for the next era of web imagery, supporting features like HDR (High Dynamic Range), wide colour gamuts with 12-bit depth, and full transparency. Browser support has been growing steadily, with Chrome, Firefox, and Safari 16+ all providing native AVIF rendering. The primary trade-off is encoding speed — AVIF images take significantly longer to compress than JPEG or WebP, which can be a bottleneck for real-time image processing pipelines and high-volume workflows.
