Upload a JPG, PNG, or WebP image and upscale it 2× or 4× on your device using high-quality interpolation with optional detail sharpening. This enlarges existing pixels—it is not generative AI. Files are not uploaded or stored.

How to use this tool

1. Choose an image file from your device. 2. Select a scale factor: 2× or 4×. 3. Optionally enable detail enhancement after upscale. 4. Click Upscale image and wait for processing. 5. Download the larger image.

Worked example

Example: upscale a 500×500 icon by 2× to 1000×1000 for a presentation slide—edges may look softer than a native high-resolution source.

How it works

Upscale an image by 2× or 4× using browser canvas interpolation, with an optional sharpening pass. This increases pixel dimensions but cannot recover detail that was not in the original.

Limitations

Results are based on the inputs you provide and may not cover every edge case. This tool is for general use and is not professional advice.

Privacy and file handling

Your image stays on your device and is not uploaded.
