Frequently asked questions
Is this AI upscaling?+
No. It uses high-quality resampling plus sharpening, which gives cleaner enlargements but cannot invent new detail like AI models.
Are my files uploaded anywhere?+
No. The conversion runs inside your browser, so your file never leaves your device.
Is it free?+
Free accounts get a few tasks per day; sign up for more, or go Pro for unlimited use and larger files.
Is there a file size limit?+
Files are processed on your device, so the practical limit is your browser's memory. Not AI: it enlarges cleanly but cannot add real detail.
Does it work on my phone?+
Yes. Modern mobile browsers run this tool, although large files are faster on a computer.
