Note: This tool uses browser-based interpolation for upscaling. It increases dimensions but cannot reconstruct missing detail.
• Works best for graphics, screenshots, and illustrations
• Requests high-quality browser image smoothing
• Processing happens entirely in your browser
How do I enlarge an image 2x or 4x?
Choose an image, select a 2x, 3x or 4x scale factor, and download the enlarged PNG. Both width and height are multiplied by that factor using the browser's image smoothing.
- Select an image and check its original dimensions.
- Choose 2x, 3x or 4x and review the resulting dimensions.
- Run the upscaler and inspect the downloaded PNG at its intended display size.
Worked example
An 800 × 600 px image at 2x.
A 1600 × 1200 px PNG. At 4x, the same input becomes 3200 × 2400 px.
Supported behavior and limitations
This tool uses canvas interpolation, not AI detail reconstruction. It cannot recover detail absent from the source. A 4x enlargement creates 16 times as many pixels and can require substantial memory. PNG output can be larger than the original JPEG.
Will enlarging fix a blurry photo?
It increases pixel dimensions and smooths scaling, but does not reconstruct missing detail. Start with the sharpest, largest original you have.
Should I upscale before compressing?
Use the dimensions required for the final placement, then compress if the exported file is too large. Avoid enlargement when the original already has enough pixels.
