Frequently Asked Questions
Is ClarityLens really free?
Yes. ClarityLens is completely free to use, supported by lightweight advertising rather than subscriptions or paywalls.
Are my photos uploaded to a server?
No. Every image-quality job happens locally in your browser using an on-device processing engine. Your photo is never sent anywhere.
How is this different from just resizing an image?
A resize stretches or interpolates existing pixels, which looks blurry at larger sizes. ClarityLens runs a real super-resolution neural network that reconstructs plausible detail, so edges and textures stay sharp.
What image formats can I use?
JPG, PNG, WebP, and other formats your browser can natively decode.
What scale factors are available?
2x, 3x, or 4x. Higher scale factors take longer to process since the model works through more, and larger, image patches.
Why was an improvement level disabled?
ClarityLens calculates the finished pixel count before starting. It disables a level when that output would exceed the safe device limit, because a very large AI result can exhaust browser memory and freeze the page. Choose a lower level or a smaller source image.
Does this work on mobile?
Yes. ClarityLens works in modern mobile browsers with WebGL support. Phones use a lower output-pixel safety limit, so 3x or 4x may be disabled for a large source image.
Do I need WebGL?
Yes. AI upscaling needs GPU acceleration via WebGL to run at a usable speed. If your browser reports WebGL is unavailable, try a recent version of Chrome, Edge, Firefox, or Safari with hardware acceleration enabled.
