Videos are processed on your device, never uploaded.
iPhone videos look incredible — and they're huge. A minute of 4K can run to hundreds of megabytes, far too big to text, email or upload to a portal. A video compressor re-encodes the clip so it's dramatically smaller while staying sharp, so it actually sends.
ConvertEase compresses video entirely on your iPhone. Pick a target size or quality, and it shrinks the file in seconds — no slow uploads to a website, no watermarks, no ads, and no limit on how long or how high-resolution your clip is.
