SizeCap: Compress Video to MB

Compress to a chosen MB cap. SizeCap verifies the finished file is at or below the limit before delivering it.

SizeCap compresses a video to a file size you choose, and checks the real bytes before calling it done.

Pick a video, set a cap (10, 25, 50, or 100 MB, or type your own), and SizeCap works out the bitrate from your number. After compressing, it reads the finished file's actual size. If the file is under your cap, you get it. If your cap is too small for the clip's length, it tells you the smallest size that would work, instead of handing you a file that still fails to upload.

WHAT IT DOES • Compresses up to 9 videos in one run, each one under the size you set • Shows the original size, the result size, and the time it took • Imports from Photos, Files, or the iOS share sheet • Lets you choose Automatic, Quality (HEVC), or Compatibility output • Keeps HDR clips in HEVC Main 10 with HDR color information • Preserves separate audio tracks, or removes every audio track when you want silence • Queues share-sheet videos safely, then imports them when you open SizeCap to review settings • Restores the current task after relaunch, keeping finished results and restarting interrupted items • Pauses the batch when storage is low so you can free space and continue without redoing finished items • Shows source names when available and lets you remove individual videos before a batch starts • Lowers resolution before quality collapses when a small cap calls for it • Saves to your photo library or hands the file to the share sheet • Lets you keep or remove the capture date on compressed copies; location is not copied • On iOS 26, a user-started compression can continue in the background with system progress • Cancel any time; completed batch results stay available • Leaves your original video untouched

WHY A NUMBER, NOT A SLIDER Email attachments, course platforms, and upload forms reject files by size. A quality slider makes you guess and re-export until something fits. SizeCap starts from the limit and does the math for you.
