Common questions

Is Img.Upscale better than ON1 Resize AI for upscaling old family photos?

For most old family photos (which are usually JPG or PNG), Img.Upscale is better because it's faster, cheaper, and easier to use from a phone or browser. ON1 Resize AI is overkill unless you're printing them at very large sizes.

Can I use Img.Upscale or ON1 Resize AI on my phone?

Img.Upscale works in a phone browser, but there's no dedicated app, so the experience is clunky. ON1 Resize AI has no mobile version at all — it's desktop-only.

Which tool is better for batch upscaling 100 photos at once?

ON1 Resize AI is much better for batch processing. Img.Upscale's free tier is very limited, and even the paid version doesn't handle large batches as smoothly as a desktop app.

Is ON1 Resize AI worth $50 if I only upscale a few images per month?

No. For occasional use, Img.Upscale's free tier or $19/year plan is far more cost-effective. ON1 Resize AI is worth it only if you upscale frequently or need professional print quality.

Do I need an internet connection to use these tools?

Img.Upscale requires a stable internet connection because it processes images in the cloud. ON1 Resize AI works entirely offline once installed.

Img.Upscale wins for speed, price, and ease of use; ON1 Resize AI wins for professional quality and batch RAW processing.

If you just want to quickly improve a few photos without spending much money or time, start with Img.Upscale's free tier — it's fast and dead simple. If you're a photographer who needs professional quality, RAW support, and batch processing, invest in ON1 Resize AI. For most everyday people, Img.Upscale is the smarter choice.
