UpSynth

UpSynth is a web-based image editor that uses AI to enhance photos with a focus on user control. It combines three core functions: upscaling images to higher resolutions, restoring specific damaged areas like faces, and modifying content based on text prompts. The tool works directly in your browser, letting you upload an image and apply these processes in a step-by-step, non-destructive workflow. You can undo steps and, crucially, use a 'magic' slider to dictate how much creative liberty the AI has, from conservative reconstruction to more imaginative detail generation.

What sets UpSynth apart is its selective approach. Instead of applying a blanket AI effect to the entire image, you can mark specific areas for restoration or modification. This is ideal for fixing distorted details in an old portrait or removing an unwanted object without reprocessing the whole scene. The upscaling also intelligently reduces common issues like JPEG artifacts and noise while aiming to preserve the original image's structure and feel.

This tool is most useful for photographers dealing with archival material, graphic designers preparing low-res assets for print, or anyone with a collection of old scans, movie posters, or wedding photos that need careful enhancement. It's built for situations where accuracy matters—you want to sharpen and repair an image, not completely reinvent it with unpredictable AI generation.
