Browser upscaling increases pixel dimensions. It is not an AI enhancement model.

Are images uploaded to a server?
No. UploadReady V1 processes selected images locally in your browser and does not store them.
Is this AI upscaling?
No. V1 uses browser canvas scaling, so it increases pixels but cannot invent real detail.
Why can the result look soft?
Upscaling stretches existing pixels. Start from the highest-quality source possible.
What formats are supported?
V1 supports JPG, PNG, WEBP and best-effort HEIC/HEIF conversion where your browser and file allow it. PDF tools are intentionally not included in this first image-focused release.
