Features
Straight from your Photos library
Pick videos and photos right from your camera roll, and save the results back to your photo library. Folders in the Files app work too.
AI super resolution
Powered by Real-ESRGAN running entirely on-device, ReMaster reconstructs lost detail as it enlarges — up to 4× sharper, all the way to 4K. A faster Standard (Lanczos) mode is there when you're in a hurry.
Smooth 60fps with AI frame interpolation
Turn 30fps video into silky-smooth 60fps. Advanced frame interpolation (RIFE) generates natural in-between frames so motion feels alive again.
Batch processing
Select multiple items in the picker — or point ReMaster at a folder — and it remasters every video and photo inside, one after another. Perfect for reviving an entire archive of memories.
Wide format support
Bring in what you have and choose what you get back.
- Video: MOV, MP4 and M4V
- Photos: JPEG and PNG (HEIC is converted automatically on import)
- Output: MP4 / MOV / JPEG / PNG
Private by design
Every pixel is processed locally using the Apple Neural Engine and GPU. Your videos and photos never leave your device — and no account is required.
Questions & answers
Are my videos uploaded anywhere?
No. All processing runs on your device using the Apple Neural Engine and GPU. Nothing is sent to a server, and there is no account to create.
How long does it take?
It depends on your device, the length of the video and the settings you choose. AI super resolution to 4K is the most demanding; the Standard (Lanczos) mode is much faster when you need a quick result.
What does ReMaster Premium do?
ReMaster is free to use. Premium is a one-time purchase that removes the watermark from exported videos.
Which formats are supported?
MOV, MP4 and M4V for video; JPEG and PNG for photos, with HEIC converted automatically on import. You choose the output format: MP4, MOV, JPEG or PNG.
