Foca Upscaler: Practical Image Enhancement for Photos and Artwork

Image enhancement is useful when an original photo or piece of digital artwork has the right composition but not enough resolution for its intended use. Foca Upscaler is a browser-based tool for improving image quality without requiring a desktop installation or a local GPU.

Foca offers two different workflows. Foca Sharp focuses on keeping lines, text, colors, and the original structure close to the source. Foca Physics takes a more reconstruction-oriented approach, using the visible content, materials, and lighting in an image to produce natural-looking detail. This makes the workflows useful for different kinds of photos, product images, artwork, and other visual assets.

Useful workflows for different images

• Foca Sharp for graphics, text, product images, and sources that are already fairly clear.
• Foca Physics for portraits, architecture, landscapes, and more difficult photographic sources.
• Anime upscaling for illustrations, manga, game characters, and other stylized artwork.
• Old Photo Restoration for faded, blurry, or low-contrast photographs.

Results can be previewed with a draggable Before/After comparison and inspected at higher magnification. The service supports PNG, JPG, WebP, and transparent images, with output sizes up to 16K depending on the workflow and source. For anyone working with photos or digital artwork, Foca Upscaler is a practical way to test a larger, cleaner version of an image directly in the browser.
