Pixelpaper's image enhancer cleans up and enlarges photos directly in your browser. It sharpens soft details with an unsharp mask, optionally smooths sensor noise, and upscales up to 4× using high-quality resampling — all without uploading your image anywhere.
Because the free tier runs locally on your device, it is private by design and instant for most photos. For genuinely difficult, low-resolution images, an optional AI HD (Pro) mode can offload to a server-side super-resolution model.
Frequently asked questions
Is the image enhancer free?
Yes — sharpen, denoise and up to 4× upscale are free, with no sign-up or watermark.
Are my images uploaded?
No. The free tier runs entirely in your browser; your image never leaves your device. Only the optional Pro AI HD mode sends data to a server, and it is clearly labelled.
How much can I upscale?
Up to 4×, capped at 4000px on the long edge so processing stays fast in the browser.
What is AI HD (Pro)?
An optional paid mode using a server-side AI model for stronger results on tough photos. The free local tier always works without it.
