Output
The target size is shown beside your image before you run anything — 8× on a 3000px photo is 24000px wide, which is a request no service will finish quickly.
With REPLICATE_TOKEN set on the backend this runs Real-ESRGAN, which invents
plausible detail — edges, hair, texture. Without it the page falls back to a high-quality
canvas resample: bigger, cleanly filtered, but no detail that was not already there.

Frequently asked questions
What does AI Image Upscaler do?
Upscale photos up to 4× without losing detail. It runs on ToolMunch's own API, so the result comes back to the page with nothing to install.
Is AI Image Upscaler free to use?
Yes. AI Image Upscaler is completely free on ToolMunch — no trial, no premium tier holding back the main feature, and no daily or hourly cap on how many times you can use it.
Do I need to create an account or sign up?
No. There is no account, no email address, and no login. Open AI Image Upscaler, do the job, and take the result — nothing is gated behind a signup form.
Where is the work done?
AI Image Upscaler sends what you give it to ToolMunch's own API, does the work there, and returns the result to your browser. It is used to answer that one request — it is not sold, shared, or added to an advertising profile.
Does AI Image Upscaler work on Mac, Windows, and phones?
Yes. AI Image Upscaler runs in any modern web browser on Windows, macOS, Linux, Chromebook, Android, and iOS. There is nothing to download or install.
Can I use it as many times as I want?
Yes. There is no queue, no per-hour quota, and no counter that runs out — run AI Image Upscaler as often as the work needs.
