AI Image Upscaler
AI Image Upscaler is a browser-based tool for enlarging photos locally with WebGPU. Supports PNG, JPEG, and WEBP, up to 10 files, with 2x or 4x upscaling.
Overview
AI Image Upscaler is a client-side image enhancement tool for enlarging photos and clarifying detail in the browser. Its homepage describes it as a secure 4x ultra-HD enhancer that uses local WebGPU acceleration and keeps image data private by avoiding uploads.
The interface shown on the site supports drag-and-drop uploads and file browsing, with multiple-image processing for up to 10 files at once. The visible controls point to a straightforward workflow for users who want quick upscaling without moving images into a separate cloud service.
Core features
2x and 4x upscale modes
Choose between 2x HD and 4x Ultra HD upscaling options depending on how much enlargement is needed.
Batch upload support
Upload multiple files in one session, with support for up to 10 images at a time.
PNG, JPEG, and WEBP input
Accept PNG, JPEG, and WEBP files, covering the common formats used for photos and web graphics.
10MB per-file limit
Handle files up to 10MB each, which sets a clear per-image size limit for the browser workflow.
Common use cases

Handle a small batch of files
Process a small set of related images at once, such as a batch of product photos or illustrations, using the multi-upload limit shown on the page.
