Submit files to /v1/convert, poll the job endpoint, then download outputs programmatically.
Animated, sequence, or multipage inputs need explicit frame/page handling.
Converting HEIF to AVIF decodes the source image and writes a AVIF output. Use this route when AVIF is a better fit for compatibility, file size, editing, or delivery.
AVIF can produce strong compression, but aggressive settings may introduce smoothing, color shifts, or detail loss. Encoder effort and quality settings matter.
Convert JPG/PNG/WebP to AVIF for modern web delivery. Offer JPG/PNG/WebP fallbacks where compatibility matters.
Known metadata support: Exif, XMP, item properties, thumbnails, derived images.
