Upscale to 4K with AI
Turn blurry, low-resolution photos and videos into stunning 4K clarity. WishPix's AI upscaler adds real detail, not just smoothing, making old screenshots, compressed photos, and SD videos look brand new.
Why WishPix's 4K upscaler is different
Not just pixel stretching. Our AI reconstructs actual detail, sharpens textures, and fixes compression artifacts.
Real detail recovery
AI reconstructs textures, edges, and fine details that traditional upscaling can't recover. Hair, fabric, and text become crisp and readable.
Video upscaling
Upscale entire videos frame-by-frame to 4K. Old phone videos, SD recordings, and compressed clips get a dramatic quality boost.
Fast processing
Cloud AI handles the heavy lifting. A typical photo upscales to 4K in 5-10 seconds, even on older Android devices.
No watermark
Your upscaled images are clean. No watermarks, no branding. Free users get full-quality output just like premium users.
Artifact removal
JPEG compression artifacts, blocky edges, and colour banding are automatically cleaned up during the upscaling process.
Works on any phone
Processing happens in the cloud, so you don't need a flagship phone. Any Android 7.0+ device works perfectly.

Frequently asked questions
What does AI 4K upscaling do? +
AI 4K upscaling uses deep learning to intelligently add detail and clarity to low-resolution images and videos, enhancing them up to 4K (3840×2160) resolution. Unlike basic interpolation which just stretches pixels and creates blurriness, AI upscaling reconstructs actual textures, sharpens edges, and removes compression artifacts.
Can I upscale videos to 4K? +
Yes. WishPix supports both image and video upscaling to 4K. Video upscaling processes each frame individually with AI for consistent quality throughout. MP4 files are supported, and the output maintains the original frame rate.
Is WishPix 4K Upscaler free? +
Yes. WishPix includes free daily credits for 4K upscaling. Free users get full-quality 4K output with no watermarks. Premium subscribers get unlimited upscaling and priority queue processing.
What formats are supported? +
For images: JPG, PNG, and WebP. For videos: MP4. The upscaled output is saved in the same format at 4K resolution. Maximum input file sizes depend on your subscription tier.
How long does upscaling take? +
A typical photo takes 5-10 seconds. Short videos (under 30 seconds) take 1-3 minutes. Processing happens in the cloud, so your phone's hardware doesn't affect speed.
Will upscaling make a blurry photo perfect? +
AI upscaling significantly improves quality, but there are limits. A 50×50 pixel image won't become a professional photo. Best results come from images that are at least 200–300px on the shortest side. The AI adds real detail but can't invent content that was never captured.
