About this tool
Small logos, icons, old web graphics and thumbnails often need to be bigger for print, slides or a new website. This tool multiplies the width and height of your image by the factor you choose and shows the exact output size before you start.
Honest note: this is high-quality enlargement, not AI. The image is enlarged in several smooth passes so edges stay clean instead of blocky, but no new detail is invented. A blurry photo will become a bigger, still-soft photo. It works best on clean graphics, line art, pixel art and images that are already fairly sharp.

Good to know
Why some factors are greyed out
A 24x enlargement of a 1000 px image would be 24,000 px wide — far more than a browser can draw. Limits depend on your device: phones are capped around 16 megapixels, computers allow more. Smaller originals unlock higher factors.
Best output format
PNG keeps every pixel without new compression and is the safest choice for graphics. For big photos, JPG or WebP give much smaller files.
Frequently asked questions
Is this AI upscaling?
No. Real AI super-resolution needs large models that are slow or crash on many phones when run in a browser. Rather than mislabel it, we offer clean multi-pass enlargement and say so clearly.
Will the result be sharper than my original?
It will be bigger and smooth, but not more detailed. Enlarging cannot recover detail that was never captured.
What's the biggest image I can create?
About 16 megapixels on phones and up to 100 megapixels on computers with enough memory. The tool checks this before it starts so your browser doesn't freeze or crash.
Is my image uploaded?
No. The enlargement happens entirely in your browser, and the file never leaves your device.
