Enhance image quality online — free, private, no API

Blurry, small or dull photos hurt product listings, social posts and website banners. This free image enhancer upscales your picture up to 4x, cleans up noise and compression artefacts, sharpens edges and corrects contrast — all in your browser tab. Drag the divider on the preview to compare before and after, then download the result as PNG, JPG or WebP.

What it does

Lanczos upscaling — a high-quality resampling method that keeps edges cleaner than a normal browser resize.
Edge-preserving noise cleanup — smooths grain and JPEG blocks before enlarging, so they don't get magnified.
Luminance sharpening & clarity — sharpens detail without colour fringing or harsh halos.
Auto contrast, brightness and colour — quick fixes for flat, dull or dark photos.
Transparent PNG support — logos and cut-outs keep clean, transparent edges.

Note: this tool improves what is already in your image. It is not generative AI, so it will not invent facial features or text that were never captured — for very tiny or heavily damaged images, expect a cleaner and sharper result, not a brand-new photo.

Frequently Asked Questions

Is my image uploaded anywhere?

No. Everything happens in your browser using JavaScript and the Canvas API. Your photo never leaves your device, and no API key or account is needed.

Is this AI upscaling?

No. It uses classic Lanczos resampling, edge-preserving noise cleanup and sharpening. It makes images larger and crisper but cannot create detail that isn't in the original.

How large can the output be?

You can upscale 2×, 3× or 4×. To keep your browser stable, very large outputs are automatically limited and you will see a note when that happens.

Which format should I download?

PNG is lossless and keeps transparency. JPG and WebP give smaller files — use the quality slider to balance size and sharpness.
