Upscale any image with AI, right in your browser
Enlarge photos to 200% or 400% resolution and sharpen detail — instantly, for free, with nothing ever leaving your device.
From blurry to sharp in three steps
Upload your photo
Drag and drop a JPG, PNG, or WEBP file. It's decoded locally — nothing is sent anywhere.
Pick 200% or 400%
Choose how much larger you want the image, plus whether you want a PNG or JPG back.
Download instantly
TensorFlow.js resizes and sharpens the image on your device, then hands you the file. No watermark.
Built to actually be free
Private by design
Your image is processed entirely on your own device. It's never uploaded to a server or stored anywhere.
Fast, no queue
There's no server to wait on. Processing starts the moment you hit upscale.
No catch
No account, no email capture, no watermark, no daily limit hiding behind a paywall.
Common questions
Is this image upscaler really free?
Yes — there's no signup, no credit card, and no watermark added to your download. Because the upscaling runs using your own device rather than a paid server, there's no per-image cost that would need to be recouped from you.
Do my photos get uploaded anywhere?
No. The AI model runs locally in your browser using TensorFlow.js. Your image stays on your device from start to finish.
What's the difference between the PNG and JPG output?
PNG is lossless, so it's the better choice for graphics, text, logos, or anything with sharp edges. JPG compresses the file to a smaller size, which suits photos you plan to share or upload elsewhere.
How much can I enlarge an image?
Choose 200% to double the width and height, or 400% to quadruple them. For 400%, the tool automatically runs two enhancement passes to preserve more detail than a single large jump would.
Will this work on my phone?
Yes, it works on mobile browsers. Very large images or the 400% option can take longer on older phones, since all the processing happens on your device.
