ImageUpscaler
A no-friction browser upscaler with a sensible spread of repair tools sharing one credit pool, priced well below the desktop alternatives. The credit ladder is the catch: the free allowance is a taster, and the cheapest paid tier covers 50 images a month. The operator is anonymous, which is worth weighing before uploading client work.
Pros
- Upscales to 16K rather than a fixed 2x/4x ceiling
- Deblur, JPEG artifact removal and enhancement share the same credit balance
- Handles JPG, PNG, WEBP and BMP up to 30 MB with no install
- Credits also cover video at 5 credits per file
- Entry paid tier at $9.90/month undercuts most desktop upscalers
Cons
- No company name or country published anywhere on the site
- Free allowance is about one image a month
- No API, so bulk work is manual
- Processing takes 10-40 seconds per image, which is slow for batches
