Upload a low-resolution photo, upscale it 4x and sharpen it with AI, and optionally colorize black and white photos too. Free, runs entirely in your browser.
Whether you're rescuing an old low-resolution family photo, sharpening a product shot for an online listing, or bringing a faded black-and-white print back to life, the AI model downloads once to your browser and runs locally from then on — so you can enhance photos without waiting on an upload or a server queue.
Is it free?
Yes, no account needed.
Does my photo get uploaded anywhere?
No, upscaling and colorizing run entirely in your browser.
How much does it upscale by?
4x — input is capped at 480px on the longest side before upscaling.
Do I need to sign up?
No.
Can I colorize and upscale at the same time?
Yes, check the colorize box and the photo is colorized first, then upscaled.
How long does upscaling take?
After the AI model finishes downloading (once per session, then cached), a single photo typically processes in a few seconds to under a minute, depending on your device's hardware.
What resolution do I end up with?
Your image is upscaled 4x from the (possibly downscaled) input — for example, a 480px-wide photo becomes roughly 1920px wide — and downloaded as a PNG.
Which browsers and devices does it work on?
Any recent version of Chrome, Firefox, Safari, or Edge, on desktop or mobile — no extra software needed, though a device with WebGPU support processes images noticeably faster than one relying on the WebAssembly fallback.
