Frequently Asked Questions
What is an AI image upscaler and how is it different from traditional resizing?
An AI image upscaler uses neural networks to intelligently add new pixels when enlarging an image, predicting what details should exist at higher resolutions. Unlike traditional resizing (which simply stretches pixels and creates blur), AI upscaling generates realistic textures, sharpens edges, and recovers fine details. The result is a larger image that looks naturally high-resolution rather than blurry or pixelated.
How does AI upscaling and color enhancement work?
Our AI analyzes your image, enhances color depth and vibrancy, then intelligently scales it from 2x to 16x based on your choice. It restores faded tones, reduces noise, and preserves fine details — especially effective for old photos or images with dull colors. Simply upload, select your scale, and get results in seconds.
What scaling options are available (1080p, 4K, 8K, 16K)?
Choose from 2x, 4x, 8x, or 16x scaling. 2x is ideal for web and 1080p, 4x for social media and 4K, 8x for standard prints, and 16x for large-format displays and ultra-high 16K resolution. Each option includes AI color enhancement for vibrant, crystal-clear results. Professional plan unlocks up to 16x scaling.
What's the maximum resolution I can upscale an image to?
You can upscale up to 16x, which takes a 1000×1000 pixel image to 16000×16000 — well beyond 8K. Free accounts can upscale up to 4x; Starter and Professional plans unlock 8x and 16x.
How large should my source image be to get a sharp 4K result?
For true 4K output (3840 pixels on the long edge), a source of about 1000 pixels works well with 4x upscaling. Smaller sources still work — the AI reconstructs detail — but starting above 500 pixels gives noticeably cleaner results.
What resolution do I need for printing?
Print needs about 300 DPI: an 8×10 inch print requires roughly 2400×3000 pixels, and an A2 poster around 5000×7000. Upscale at 4x for standard prints and 8x or 16x for posters and large-format printing.
Will upscaling improve image quality without losing details?
Yes! Our advanced AI doesn't just increase resolution — it enhances details, sharpens edges, reduces noise, and improves overall quality. Unlike simple resizing that creates blur, our neural networks are designed to preserve and enhance image quality throughout the upscaling process.
Is it free? How do credits work?
You get 10 free credits every month — no credit card required, no trial expiration, no hidden fees. Free credits reset monthly and don't roll over. Need more? Upgrade to Starter ($19.90/mo, 600 credits), Professional ($39.90/mo, 1,800 credits), or Premium ($69.90/mo, 3,600 credits) anytime — or buy a one-time credit pack that never expires. Cancel anytime with no commitment.
What image formats and devices are supported?
We support JPG, PNG, HEIC, and WebP formats for both input and output. Our web-based tool works on all devices — desktop, tablet, and mobile browsers — with full functionality and no app download required.
Can I upscale anime, cartoon, or AI-generated images?
Absolutely! Our AI handles anime, cartoon, manga, and AI-generated images with excellent results. It preserves clean lines, flat colors, and stylistic details unique to illustrated content. Whether you're enhancing Midjourney outputs, anime screenshots, or digital art, our tool maintains the artistic style while increasing resolution up to 16x.
Can I use upscaled images commercially?
Yes! All enhanced images are yours to use for any purpose, including commercial projects like marketing, e-commerce, print, and portfolios. This applies to all plans, including the free tier — as long as you have the rights to the original image.
