Hieu Dinh
Founder of Compresto
Hieu Dinh is the founder of Compresto (formerly CompressX), a native macOS app that batch compresses videos, images, PDFs, and GIFs while keeping quality intact.
Hieu builds tools for macOS creators — focusing on media compression, hardware-accelerated encoding with VideoToolbox, Apple Silicon performance, and offline-first workflows that keep files on-device. Compresto is used by thousands of independent creators, designers, and developers to reclaim storage without sacrificing quality.
He writes most of the technical guides and comparisons on this site, drawing on hands-on work with codecs (H.264, H.265/HEVC, AV1), image formats (HEIC, WebP, AVIF), and PDF optimization.
