UpSynth

The first upscale is free on UpSynth, and a one-time trial plan with 200 credits and full feature access sits between that and the monthly subscriptions.

UpSynth is an AI image upscaler and photo editor that enlarges, sharpens, restores and modifies photos and graphics in one editor, with inpainting and outpainting for changing or extending an image.

The aim is controlled workflows that give more accurate, natural results.

Paid plans are priced by credits and concurrent workers.

Basic gives you 1 worker and 1000 credits a month, enough for 25 standard upscales, 10 large upscales or 40 edits.

Standard has 3 workers and 2250 credits, or 60 standard upscales, 25 large ones or 90 edits.

Premium has 5 workers and 11000 credits, covering 300 standard upscales, 125 large upscales or 440 edits.

Prices rise steeply at the top, so the worker count matters most if you run many upscales in parallel.

Occasional users can stay on the trial or Basic.
