Free Image Upscaler to 4K
Low-res 240p / 480p photos boosted to crisp 1080p, 1440p or 4K.
Breathe new life into small, blurry or old images. The upscaler detects whether your source is 240p-class, 480p, 1080p or 1440p, then progressively enlarges it in high-quality passes to 1080p Full HD, 1440p QHD or 4K Ultra HD — finishing with an adjustable sharpening filter and your choice of PNG, WEBP or JPEG output.

Frequently asked questions
Can I upscale a 240p image to 4K?
Yes. The multi-pass engine enlarges 240p-class images step by step up to 3840×2160 with smoothing and sharpening to keep edges clean.
Will upscaling make a blurry photo perfectly sharp?
Upscaling adds pixels and enhances edges, but it cannot recover detail that was never captured. Results look dramatically cleaner, not magically re-photographed.
Which output format is best after upscaling?
PNG preserves maximum quality, WEBP gives the smallest files, and JPEG is the universal choice for sharing.
Is the upscaled image uploaded anywhere?
No. All enlargement and filtering run on a local canvas in your browser.
