What our research says

Bigjpg

For anime and illustration upscaling it remains a reference tool, and the multi-month bundles are cheap — $22 covers a year. It shows its age against diffusion-based upscalers on photographic detail, and free-tier jobs require keeping the browser tab open.

Pros

  • Distinct anime-tuned models keep lines and flat colors clean
  • Very low cost: $22 buys twelve months of paid limits
  • Clients on every major platform plus an API
  • Free tier is enough to evaluate output quality

Cons

  • Interpolates rather than reinvents detail — soft results on complex photos
  • Free jobs fail if you close the browser; images auto-delete after 24 hours
  • Anonymous operator; processing defaults to mainland-China servers

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
