Ojoy is an AI-driven image upscaling tool designed for users looking to enhance low-resolution images, including Memoji, photos, and illustrations. It operates entirely within the browser, leveraging machine learning models from UpscalerJS, Waifu2x, and TensorFlow.js to upscale images without uploading them to a server. This client-side processing ensures user privacy and security. Ojoy is particularly useful for improving the quality of stickers, avatars, logos, and other images where the original high-resolution source is unavailable.

Key Features

Ojoy offers two primary upscaling modes: one optimized for photographic content and illustrations, and another labeled 'Sharp' with options for 2x, 3x, and 4x upscaling. The 'Sharp' mode also includes a feature to replace transparent backgrounds with a solid color, addressing a limitation in the models used which only support 3-channel images. Users can adjust settings such as noise reduction to fine-tune the output.

Usage

To use Ojoy, users select the desired upscaling mode and adjust available settings. They can then upload their image or use a sample image provided by Ojoy for testing. The processed image is displayed along with details such as the new resolution, processing time, and any applied settings. Users can save the enhanced image directly from the browser.

Benefits and Limitations

Ojoy's client-side processing and use of advanced machine learning models make it a convenient and private solution for image upscaling. However, its effectiveness can vary, particularly for images containing text. Additionally, upscaling higher resolution images can be resource-intensive and may strain system resources like the GPU.
