Stop choosing between 4K quality and file size. You filmed it in 4K. Then WhatsApp rejected it for being too big. You tried another compressor — and it dumped your footage down to 1080p, ruining the quality you bought your iPhone for. Crispy fixes that. Crispy is a video compressor built around a single promise: shrink your file size dramatically without throwing away your resolution. A 500 MB 4K clip becomes 50 MB — still in true 4K. Then when Instagram, TikTok, or Reels re-compresses your upload, they have far less quality left to butcher. — WHY CRISPY IS DIFFERENT — - Keep your 4K. Most compressors quietly downscale to 1080p or 720p to hit smaller file sizes. Crispy uses smart bitrate compression so 4K stays 4K, HDR stays HDR. - 100% on-device. Your videos never leave your iPhone. No cloud uploads, no servers, no accounts, no tracking. Compress on a plane, in the subway, anywhere. - Built on Apple AVFoundation. Native Apple video technology — not a hacky FFmpeg wrapper. Faster encoding, lower battery drain, full HEVC and H.264 support. - No watermarks. Ever. — ONE-TAP PRESETS FOR EVERY PLATFORM — Why fiddle with bitrate sliders? Crispy includes 15+ optimized presets: - WhatsApp — fits the 16 MB attachment limit - Instagram Reels — vertical, platform-perfect bitrate - TikTok — optimal upload spec - YouTube Shorts — 9:16 ready - X (Twitter) — under the upload cap - Telegram, Discord, Signal - Gmail, Outlook, iCloud Mail — email-friendly sizes - Save to Photos — storage saver mode One tap. Done. No guesswork. — FEATURES YOU'LL ACTUALLY USE — - Batch compression — queue dozens of videos at once - Custom mode — full control over resolution, bitrate, frame rate, codec (H.264 / HEVC) - Resize and crop for any aspect ratio - Trim before compressing — drop the parts you don't need - Metadata preserved — keep dates, location, and HDR data - Built-in duplicate video scanner — find and remove identical clips eating your storage - MP4, MOV, HEVC, H.264 supported - Estimated output size shown before you compress - Dark Mode, Dynamic Type, VoiceOver — fully accessible — WHO IT'S FOR — Content creators who shoot in 4K and need to upload without quality loss. Travelers and parents whose 256 GB iPhones are full of memories. Anyone who's ever stared at the "file too large" error in WhatsApp. Editors who need to send proxies. People who care that their videos look as good as the day they were filmed. — PRIVACY-FIRST. ALWAYS. — Crispy does zero cloud processing. Your videos are compressed entirely on your iPhone's chip. We don't see them. We can't see them. There's no upload, no analytics on your content, no third-party SDKs touching your footage. If you're tired of compressor apps that quietly ship your camera roll to a server somewhere, this is the one. — FREE WITH ADS, OR AD-FREE FOREVER — Crispy is free to use with all features unlocked — supported by ads.
