Multiple upscaling models
Upscale images with AI using selectable models, including options for general upscaling, face restoration, and higher-quality processing.
Overview
Image UpScaler is a web-based AI image upscaling service that enlarges photos, artwork, anime, and other images without requiring an account or sign-up for small-scale use. The main upscaler lets users upload an image, choose a model, and generate a higher-resolution version directly in the browser.
The service emphasizes configurable output and practical workflow details: users can choose between general upscaling, plus-style quality, or face restoration; process images in bulk; and download finished files from a gallery. The site also provides a separate browser-based bulk image converter for converting files to PNG, JPEG, or WebP.
Source pages describe a free daily quota, with additional quota available through donations. Processed images are retained only briefly, and the privacy policy says uploads are not permanently stored and are deleted after processing.
Key Features
High-resolution output options
Scale images by 2x or 4x, with model-dependent output sizes up to 256MP and 16K for the General model.
Common format support
Handle PNG, JPG, and WebP inputs, with support for transparent images on the Plus and General models.
Bulk processing and downloads
Process more than one image at a time and download results individually or as a ZIP archive.
Short-term private processing
Keep uploads private during processing; the site says images are matched to a cookie-based client ID and deleted after a short retention window.
Browser-based converter
Use the separate bulk image converter in the browser to convert images to PNG, JPEG, or WebP without uploading files to a server.
Use Cases
Upscaling old or soft photos
Improve low-resolution photos that need more detail before sharing or archiving, using the model that best matches the image quality and subject matter.
Enlarging art and illustration files
Prepare artwork, anime frames, or digital illustrations for larger displays or prints, with support for transparent images on selected models.
Fixing facial detail in portraits
Restore faces that look blurry or distorted in portraits, screenshots, or group photos by choosing the face restoration option.
Batch upscaling
Process several images in one session and download the results in bulk, which is useful for batches of product shots, assets, or client files.
Local format conversion
Convert a folder of images to PNG, JPEG, or WebP in the browser when the task is format conversion rather than AI enlargement.
Pros and Cons
Pros

- Transparent images are supported in the Plus and General models.
- Bulk processing and ZIP download make it practical for multiple files.

Cons

FAQ
Is the image upscaler free to use?
Yes. The site says small-scale use is free, with no sign-up or paywall, but a daily free quota applies. When the free quota is exhausted, the account page says paid quota can be unlocked through a donation.
What happens to uploaded images after processing?
The home page says processed images are automatically deleted about 3 hours after processing, and the privacy policy says uploaded data is temporary and stored only short term for processing.
Which image formats does it support?
The site supports PNG, JPG, and WebP for the image upscaler. It also notes that animated formats like GIF are not supported.
Do I need to install anything?
The upscaler can be used directly in the browser from the website. The site also mentions an Android APK download link, and the separate bulk image converter runs entirely in the browser.
How does the quota system work?
The account page says a free daily request limit applies. If you need more quota, you can support the service with a donation; paid quota only starts after the free quota is used up.
