ON1 Resize AI

Best overall

waifu2x

For everyday users who need to upscale photos (especially from a phone or camera), ON1 Resize AI is the clear winner—it delivers excellent quality and batch processing, but it costs money and has no mobile app. Waifu2x is a free, easy web tool that works great for anime art but struggles with real-life photos and lacks any integration. The single biggest difference: ON1 is a paid, professional-grade tool for photographers, while waifu2x is a free, niche tool for anime fans.

Common questions

Is ON1 Resize AI better than waifu2x for upscaling family photos?

Yes. ON1 Resize AI is designed for real-life photos and produces much sharper, more natural results on faces and landscapes. Waifu2x will often make family photos look waxy or artifact-ridden.

Can I use waifu2x on my phone?

No. Waifu2x is a website that works on a computer browser. There is no official mobile app, and the site is not optimized for phone screens.

Does ON1 Resize AI work as a standalone program?

Yes. You can install it as a standalone app or use it as a plugin inside Adobe Photoshop and ON1 Photo RAW.

Which tool is better for upscaling old, low-resolution game sprites?

Waifu2x is better for game sprites and pixel art because its noise reduction and upscaling algorithms are tuned for that style. ON1 Resize AI is designed for continuous-tone photos.

Is waifu2x really free forever?

Yes, the official waifu2x website is free to use with no limits. Some third-party clones may have ads or limits, but the original site is free.

Can ON1 Resize AI upscale images to 4x or more?

Yes, ON1 Resize AI can upscale images up to 1000% (10x) while maintaining good quality, though results depend on the original image resolution.

ON1 Resize AI wins for photo quality and batch work; waifu2x wins for free anime upscaling—pick based on what you're enlarging.

If you're a photographer or someone who needs to enlarge real-life photos for printing, go with ON1 Resize AI—it's worth the money. If you're just messing around with anime art or old game sprites and don't want to spend a cent, waifu2x will do the job fine. Neither tool has a mobile app, so plan to use them on a computer.
