ConvertCalm is a native macOS media studio for images, video, and audio. Batch-convert PNG, WebP, HEIC, and AVIF with up to 90% compression, hardware-accelerate video conversion, trim clips, generate GIFs, and extract or mute audio. One-click presets for Instagram Reels, TikTok, YouTube, and Twitter. Built for creators who want speed without the cloud: everything runs 100% offline, and EXIF/metadata is stripped automatically.
