Upscale

Upscale

Enlarges pictures in the browser with a Gradio app built around the Real-ESRGAN model. Suits anyone who needs a bigger version of a small image without installing software.

Made by Delanoir on Hugging Face. These notes are Mindket's, written from its Space page and README; the app's own files and license are on Hugging Face.

About

What it is: This Space is a small Gradio app for enlarging images. Its repository is named ESRGAN, and the page names the Real-ESRGAN model from ai-forever. You open it in a browser, so there is nothing to install. The source gives no further description.

Who it suits: It suits people with small or low-resolution pictures who want a larger copy, and developers who want to read a short Gradio app around an upscaling model.

Industry | Who uses it | How they use it | Example
Photography | Hobby photographers | Enlarge older, low-resolution photos | Upscale a small scan of a printed picture
Online retail | Shop owners | Get larger versions of small product pictures | Enlarge a thumbnail before reusing it
Design | Designers | Start a draft from a bigger image | Upscale a low-resolution reference picture
Software | Developers | Read a short app that wraps an upscaling model | Open app.py and follow it

Skip it if you need batch processing or fine control, since the source describes only a small app.

Where to use it:

• A browser: open the Space's page on Hugging Face, with nothing to install
• A copy on Windows, macOS or Linux, using Python 3.11.9

Use case | Who | What they get back
Enlarging a picture | Anyone with a small image | A larger version of the same picture
Reading the code | Developers | A short Gradio app with three files
Running locally | Learners | A copy of the app on your own computer

How to set it up: The online copy needs nothing. For a copy on your own computer, you need the following.

• Python 3.11.9 with pip on Windows, macOS or Linux
• The Hugging Face hub client, which the first step installs
• The packages listed in requirements.txt

1. Install the Hugging Face hub client.
2. Download the Space's files into a local folder.
3. Move into that folder.
4. Install the Gradio version the Space pins.
5. Install the remaining packages from requirements.txt.
6. Start app.py.

pip install -U huggingface_hub
hf download Delanoir/ESRGAN --repo-type space --local-dir ESRGAN
cd ESRGAN
pip install gradio==5.23.3
pip install -r requirements.txt
python app.py

How to use it: Online, open the Space's page, give it a picture and run it. On your own computer, start the app with the command below and use the page it launches. The source does not describe the controls, so follow the labels.

python app.py

Example: You upload a small picture and run the upscaler. The Space returns a larger version for you to look at and save. The source gives no figures on the scale or the quality of the result.

For newcomers and experts: If you are new, open the Space online and try one small picture first, since the app runs on shared processor hardware. Compare the result with the original.

If you know the field, this is a thin Gradio wrapper around Real-ESRGAN, with Gradio 5.23.3 on Python 3.11.9 and cpu-basic hardware at Hugging Face. Running on a processor only, large images are likely to be slow.

You open the Space or run app.py
You give it a picture
The Real-ESRGAN model enlarges it
You get the larger picture back

Good to know: The source is short, so details on scale factors and limits are not available.

• License: apache-2, as listed on Hugging Face
• Cost to run: no API key or paid service is named, and the online copy runs on cpu-basic hardware
• Data it reaches: the pictures you give it, which the online Space handles on Hugging Face's servers, and a local copy downloads the Space's files
• Not for: the source lists no exclusions, so use only pictures you have the right to edit
