Foca Upscaler

Foca Upscaler is a browser-based image enhancement studio for creators, photographers, ecommerce teams, designers, and anyone who needs a clearer, larger image without losing what makes the original recognizable. It runs on desktop and mobile without a software installation or local GPU.

Three enhancement workflows and photo restoration

Foca Sharp is designed for product photos, graphics, text, design assets, and already-clear images where preserving lines, colors, and structure matters. Foca Physics is intended for photographs such as portraits, architecture, and landscapes; it uses the visible subjects, materials, and lighting as context to reconstruct natural-looking detail. A dedicated Anime workflow is tuned for line art, faces, hair, clothing, and clean color boundaries. Old Photo Restoration is a separate workflow for faded, soft, or damaged photographs.

Large outputs with room to inspect

Users can choose 2K, 4K, 8K, or up to 16K output, with a maximum long edge of 15,360 pixels. A before-and-after viewer helps review results using a draggable comparison line, zoom, pan, and full-screen viewing; mobile users can also zoom with touch gestures. Downloads are available as PNG, JPG, or WebP, and transparent PNG images can retain their alpha channel.

Designed for practical image work

Large jobs and format conversion use background processing rather than depending entirely on browser memory. Uploaded images, results, and related files are automatically removed after about 24 hours under the current retention policy. Foca is free to try, with credits and subscriptions available for people who need more processing volume.

Image generation in the same workflow

Foca also includes AI image generation with models such as GPT Image, Nano Banana, and Seedream. Generated images can be sent into the enhancement workflow for further upscaling.
