Image Upscaler is an online service for improving picture quality with AI. It started as a convolutional neural network for enlarging images and has grown into a set of tools: upscaling to as much as four times the original size, deblurring, JPEG artefact removal, enlargement and general enhancement, plus extras such as AI image generation and turning video into cartoon footage. Everything runs on the company's servers through the browser, so nothing has to be installed, and several files can be uploaded together. Each tool can be tried with three free credits a month; subscriptions raise that to between 50 and 1,000 credits. Uploaded photos are removed 60 minutes after processing, and an HTTP API is documented for developers. ## Key features - **4x Upscaling**: Raises resolution by up to four times while rebuilding edges and textures from the content of the photo. - **Deblurring**: Corrects motion blur and focus problems, with a FacePro option aimed at blurred faces. - **JPEG Artefact Removal**: Cleans the blocky compression marks left on heavily compressed files. - **Multiple Uploads**: Lets you send several files in one go instead of processing them individually. - **Wide Format Support**: Reads PNG, JPEG, WebP, HEIC, AVIF, TIFF, BMP, JFIF and PDF, and MP4 or AVI for video tools. - **Automatic Deletion**: Removes uploaded photos from the servers 60 minutes after the enhancement finishes. ## How Image Upscaler works 1. **Upload a file**: Send an image or a video from the browser; several files can be uploaded together. 2. **Choose a tool**: Pick the function you need, such as upscaling, unblurring or JPEG artefact removal. 3. **Let the servers process it**: The work runs automatically on Image Upscaler's servers, so no software is installed on your device. ## Use cases - **Enlarging Small Images**: A website owner makes a low-resolution picture big enough for a banner or a print. - **Fixing Blurry Portraits**: A photographer brings back facial detail in photos that were out of focus or shaken. - **Cleaning Compressed Files**: A blogger removes artefacts from images that have been saved or shared too many times. - **Product and Social Visuals**: A seller sharpens pictures for shop listings, ads and social media posts. - **Improving Digital Artwork**: An illustrator increases the resolution of drawings and other digital art. ## Things to know - **Free allowance**: Every user gets three free credits per month for each tool; the site notes that a subscriber has to sign out to use them. - **Subscription credits**: A subscription adds between 50 and 1,000 credits a month, valid for all current tools and ones released later. - **Files are deleted after an hour**: Uploaded photos are removed from the servers 60 minutes after the enhancement is complete. - **API quota**: The API documentation says the first 100 API calls each month are free and that an API key is required. ## FAQs ### What is Image Upscaler?
