About image editing
Pixuno's editor applies the same tonal adjustments found in desktop photo software — brightness, contrast, saturation, blur and sharpness — using CSS and Canvas filters, live in the browser. Every slider updates the preview instantly, so you're reacting to what you actually see rather than guessing a number and re-exporting to check.
Brightness and contrast fix exposure problems — a photo that came out too dark or washed-out. Saturation controls how vivid colors look, from fully grayscale at 0% up to punchy and oversaturated well above 100%. Blur softens detail (useful for backgrounds or reducing noise), while sharpness does the opposite, adding edge definition to a slightly soft photo.
Every adjustment is applied to a fresh copy of the original pixel data, never to the source file itself — so "Reset all" always gets you back to exactly where you started, and re-opening the same file gives you a clean slate every time, no matter how far you pushed the sliders on a previous attempt.

No install, works anywhere
A full adjustment panel in the browser — no desktop app to install, on any device that can open a web page.
FAQ
What adjustments are supported?
Pixuno supports brightness, contrast, saturation, blur and sharpness sliders, plus a grayscale toggle. All adjustments are previewed live.
Is the live preview accurate?
The live preview uses CSS filters applied to the image element. The exported image uses the same filter values applied to a Canvas, which should match closely in modern browsers.
Can I undo adjustments?
Click "Reset all" to return all sliders to their default values. You can also adjust individual sliders back manually.
Are filters destructive?
Filters are non-destructive — the original file is never modified. You are always applying adjustments to a fresh copy of the original image data.
Can I combine editing with other tools like Crop or Resize?
Yes — download the edited result, then open it again in Crop, Resize or Rotate to continue working on it. Each tool operates on whatever file you currently have open.
