Compresto is a native macOS app (formerly CompressX) that batch-compresses videos, images, PDFs and GIFs locally on your Mac. Drop in hundreds of files, optionally point it at a watched folder, and it shrinks them by up to 90% with no visible quality loss — all without uploading anything to the cloud.

Built by Hieu (Tony Dinh), it supports MP4/MOV, PNG/JPEG/HEIC/WebP, animated GIF and PDF, integrates with Raycast, and can save in place, replace originals or write to a separate folder. Pricing is a one-time Lifetime license ($49 Personal / $69 Standard) or a yearly subscription, with educational discounts available.
