## What is Upscal?

Enhance and upscale photos and videos directly on your iPhone or iPad with private, offline AI processing. Upscal uses Apple Metal, Metal Performance Shaders, and Core ML to process media locally without uploading your files.

Upscal improves low-resolution, blurry, or compressed media while keeping your files on your device. Enlarge photos and videos with clear details, natural textures, and flexible output settings.

PHOTO ENHANCEMENT

• Upscale photos by 2×, 4×, or 8×
• Improve clarity, edges, and fine details
• Process up to five photos in one batch for free
• Export images as JPG, PNG, or WebP
• Save results without watermarks

VIDEO ENHANCEMENT ON IPHONE

Upscal includes Fast Model for mobile video enhancement. It is optimized for the performance and memory limits of iPhone and iPad, helping you improve video resolution directly on your device.

More advanced video models, including Sharp, General, and Anime models, require the macOS version of Upscal.

PRIVATE AND OFFLINE

Your photos and videos are processed locally. Media files are not uploaded to a remote processing server, helping keep your personal content private.

FLEXIBLE OUTPUT

• Select 2×, 4×, or 8× upscaling
• Export at 720p, 1080p, 2K, 4K, or 8K
• Images: JPG, PNG, and WebP
• Videos: MP4, MOV, and M4V
• Preserve or mute video audio
• Adjust denoise and sharpening settings

GREAT FOR

• Improving blurry or low-resolution photos
• Enhancing videos for larger displays
• Restoring old images and memories
• Enlarging anime and digital artwork
• Preparing content for social media

PERFORMANCE

Requires iOS 16.6 or later. Video enhancement is computationally intensive. Processing speed depends on your device, video length, source resolution, and output scale.

For advanced AI video models and faster processing, use Upscal for macOS on an Apple silicon Mac.

### 5/5 — Best picture upscaling app

*2026-08-24*

Free and very powerful! (at least for picture upscaling)

### 1/5 — Instantly Crashes Every Attempt

*2026-08-19*

Every attempt crashes the app regardless of settings. The video I’m attempting to upscale is only 6 seconds. I’m not sure what the issue is or why this app has good reviews (fake?).

### 1/5 — Crashing

*2026-08-11*

It will convert four files successfully then fail every subsequent file no matter its format

**Developer response:** Would you mind sending the screenshots to support @upscal.app? I would like to check the issue.

### 1/5 — macht keinen Unterschied

*2026-08-09*

macht keinen Unterschied

### 5/5 — Upscal Gives You Lots of Options to Dial in Desired Files

*2026-07-21*

I discovered Upscal is the Mac app for online software I invested in a few years ago. It provides a lot of latitude in settings to help me get the images I need for a website migration project involving 4,000-plus images. The output I’m getting is superior to what I got using another Mac app. Needless to say, Upscal is doing more than filling in missing pixels; it’s revolutionizing my workflow for this critical project. Thank you to the developers for a job well-done! One piece from my wishlist: I’d love to see a 3x upscaler option as well.

### 5/5 — AWESOME!

*2026-06-20, version 4.0.3*

Quality is fantastic to upscale CG animations from HD to 4K.

### 1/5 — (?)

*2026-06-02*

To be fair, it did work. A ten second video took 1 minute and 29s to complete. The original 17mb video was a screen recording 1920x720. It upscaled it to 4K size, but it didn't enhance the video, if anything it made it slightly worse? The end result was 720p quality—File size 117mb. Same or slightly lesser quality at 10 times the file size! If you have reason to do this, download it.

**Developer response:** Hello my friend. You are using the iOS version and trying to enhance the video from your mobile phone. Frankly speaking, iPhones are great for image enhancement, video enhancement is much more computationally intensive and is limited by the hardware resources available on mobile devices.  As a result, the quality improvement may not be as significant as you expect. For the iOS version, I have claimed that it is using the traditional algorithm to upscale the video and the details improvement is not guaranteed. If you are looking for the best possible video enhancement results, I would strongly recommend using the macOS version. It has access to much more computing power and can produce significantly better results, especially for detailed and high-resolution videos. Best Regards

### 5/5 — Great

*2026-04-23*

Amazing and no scam like countless others apps do

**Developer response:** Thank you for your 5 stars!

### 1/5 — Scam

*2025-07-30*

I got free lifetime for free at the beginning of this app. After some updates, it told me that my subscription was expired. It's scam to get downloads count.

### 5/5 — Finde ich gut 👍

*2024-08-25*

App macht gut ihre Arbeit. Bilder werden sichtbar schärfer. App ist leicht zu bedienen. 5 Sterne von mir.
