{# canonical_base is the OWNING tenant's origin: all 16 Peasy domains serve the same catalogue, so a page rendered by a non-owner points its canonical at the owner instead of competing with it. Falls back to this site for static/self-owned pages. #}

About Adjust Image

Adjust brightness, contrast, saturation, and hue of JPEG, PNG, and WebP images with precise slider controls. Fix underexposed photos, boost colors, or create artistic effects — all in your browser.

How It Works

Multiple CSS filter functions (brightness, contrast, saturate, hue-rotate) are combined into a compound filter string and applied to the Canvas 2D context. Each adjustment is applied simultaneously for the best visual result.

Step by Step

  1. 1 Upload one or more images (JPEG, PNG, or WebP)
  2. 2 Adjust brightness, contrast, saturation, and hue sliders
  3. 3 100% is the original value for brightness/contrast/saturation
  4. 4 Click Adjust to process your images
  5. 5 Download the adjusted results

Tips

  • Brightness: increase for dark photos, decrease for overexposed ones.
  • Contrast: boost to make colors pop, reduce for a flat/muted look.
  • Saturation: increase for vivid colors, set to 0% for grayscale.
  • Hue rotate: shift all colors around the color wheel (e.g. 180° inverts colors).

Frequently Asked Questions

What does 100% mean?
100% is the original, unmodified value. Below 100% reduces the effect, above 100% increases it.
Can I adjust individual color channels?
This tool adjusts overall brightness/contrast/saturation. For channel-level editing, use a full image editor.
