The free preview downloads the model and processes the image locally. ImageBig does not receive or retain the image file.
About ImageBig
Useful image tools without an upload tax.
Honest about AI
Upscaling can add plausible detail and pixels, but it cannot guarantee the recovery of missing facts or print readiness.
Built around tasks
The tools are organized around real questions: required pixels, file resolution, transparency, product-photo review, and download sizing.
How the site works
A small toolset for the step before production.
Upscale
ImageBig loads the open-source ESRGAN 2× model into the browser and creates a preview up to 2048 pixels on the longest edge.
Check
Print, resolution, PNG, DTF, product-photo, and digital-download tools use local browser calculations to expose common gaps before files move into production.
Stay transparent
The site uses Cloudflare Web Analytics for aggregate traffic and Core Web Vitals, plus anonymous product events without files, IP addresses, or persistent user identifiers. See the Privacy Policy.
