As answered by people managing OpenCV and ConvertifyApp.net.
ConvertifyApp.net's answer:
ConvertifyApp.net's answer:
ConvertifyApp.net's answer:
Built out of frustration with existing converters that require signup or add watermarks. Wanted a fast, private, no-nonsense tool. Chose Rust + libvips for performance — the hardest part was getting HEIC support working by building libheif 1.21.2 from source.
ConvertifyApp.net's answer:
iPhone users who need to convert HEIC photos, web developers working with WebP and AVIF formats, and anyone who needs fast batch image conversion without installing softwar
ConvertifyApp.net's answer:
Convertify is completely free with no signup required and no watermarks. Most converters either require registration, add watermarks, or are slow. Convertify is built with Rust + libvips for maximum speed, supports 20+ formats including HEIC, and automatically deletes files after 6 hours for privacy.
ConvertifyApp.net's answer:
No signup, no watermarks, no limits on format combinations. Built with Rust + libvips — one of the fastest image processing libraries available. Supports HEIC conversion which most browser-based tools struggle with. Files are automatically deleted after 6 hours, so nothing is stored permanently. Batch convert up to 10 images at once with quality and resize controls.
