Online Image Enhancer

Enhance photos online by improving brightness, contrast, saturation, warmth, and sharpness. This tool uses PHP GD for server-side auto-level and contrast correction, while still keeping a browser preview option for quick manual checks.

Features:

• Server Enhancement: Use GD-based processing for auto-level, contrast correction, and sharpening.
• Manual Controls: Fine tune brightness, contrast, saturation, warmth, and sharpness.
• Useful Presets: Start with Auto, Brighten, Portrait, or Product settings.
• Before and After Preview: Compare the original image with the enhanced result before downloading.
• PNG Download: Save the enhanced output as a clean PNG image.

1. Improve Dull or Dark Photos

Low-light and flat-looking photos often need better brightness, contrast, and color balance. The enhancer helps make details easier to see without requiring a full photo editing application.

2. Prepare Images for Web and Social Media

Use the tool to polish product photos, blog graphics, profile images, document snapshots, and social media visuals before resizing, compressing, or converting them for publishing.
