Image Upscaler by sorabing

Enlarges and sharpens an image by 2x or 4x with the Real-ESRGAN model in a Gradio page on ZeroGPU. For anyone who needs a bigger, cleaner version of a small picture.

Made by sorabing 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 makes a picture bigger and sharper with AI. It enlarges an image two times or four times using the Real-ESRGAN model, and it runs on ZeroGPU at Hugging Face, which the README describes as free. The README is written in Thai.

Who it suits: Designers, shop owners, photographers and hobbyists who have a small or soft image and want a larger version.

Industry | Who uses it | How they use it | Example
E-commerce | Shop owners | Enlarge a small product photo | Upscale a catalog picture four times
Design | Graphic designers | Prepare a low resolution asset for larger use | Double the size of a logo mockup
Photography | Hobby photographers | Sharpen an old or small photo | Upscale a scanned family picture
Software | Developers | Study a small Gradio wrapper around an upscaler | Read app.py and requirements.txt

If you need to repair heavy damage or retouch details by hand, an image editor is the better tool.

Where to use it: It runs in two places.

• A web browser, on the Space's page at Hugging Face with nothing to install
• A local copy on Windows, macOS or Linux, which needs Python

Use case | Who | What they get back
Upscale a picture | Anyone with a small image | A version made two or four times larger
Prepare web images | Shop owners | Sharper pictures at a bigger size
Study the code | Developers | A short app.py around the Real-ESRGAN model

How to set it up: Using it online needs nothing. A local copy needs a few things.

• Python and pip
• The packages listed in requirements.txt

1. Install the Hugging Face tools.
2. Download the Space into a folder.
3. Move into that folder.
4. Install Gradio and the packages from requirements.txt.
5. Start the app.

pip install -U huggingface_hub
hf download sorabing/image-upscaler --repo-type space --local-dir image-upscaler
cd image-upscaler
pip install gradio
pip install -r requirements.txt
python app.py

How to use it: Open the Space page, add your image and choose a scale of two or four. Run it and the enlarged picture appears on the page. In a local copy, run python app.py to open the same page on your own computer.

Example: You have a small product photo and need a bigger one. You add it, choose four times, and run it. The page returns a picture with four times the size.

For newcomers and experts: Start with a two times upscale on a small image to see the difference. A four times upscale makes a much larger file, so use it when you need the size.

Real-ESRGAN is a model that predicts fine detail when it enlarges a picture. The Space wraps it in a Gradio page and runs it on ZeroGPU, where a GPU is lent for each request. The repository holds only app.py and requirements.txt.

You add an image
You choose a 2x or 4x scale
Real-ESRGAN enlarges and sharpens it
The larger picture shows on the page

Good to know: The README is two lines, so the largest input size and the output format are not described.

• License: BSD 3-Clause
• Cost to run: the README calls ZeroGPU free, and no key is named
• Data it reaches: the images you add to the page
