About Bộ lọc ảnh

OptiPix Photo Filters gives you a collection of preset filters and manual adjustment controls for enhancing your photos. Choose from preset filters like Vivid, Warm, Cool, Vintage, Grayscale, Sepia, Fade, and High Contrast — each carefully tuned to produce attractive results with a single click. For more precise control, use the manual adjustment sliders: brightness, contrast, saturation, hue rotation, and blur. Adjustments stack with presets, so you can start with a preset and fine-tune it. The real-time preview shows exactly how your photo will look before you commit. All processing uses CSS filters and Canvas rendering, running entirely in your browser with zero server interaction. Your photos remain private on your device throughout. The tool outputs high-quality PNG files at the original resolution. Perfect for quick photo enhancement before sharing, creating consistent visual styles for social media feeds, or experimenting with different looks.

How It Works

Preset filters and manual adjustments are applied using CSS filter functions (brightness, contrast, saturate, hue-rotate, blur, sepia, grayscale). The real-time preview uses CSS for performance. When you export, the filters are applied to a full-resolution Canvas element for the final output.

Use Cases

  • •Enhance photos before sharing on social media
  • •Create consistent visual styles for Instagram feeds
  • •Apply vintage or retro effects to modern photos
  • •Adjust brightness and contrast for better visibility
  • •Create black-and-white or sepia versions of color photos

Frequently Asked Questions

What preset filters are available?
Nine presets: Normal, Vivid, Warm, Cool, Vintage, Grayscale, Sepia, Fade, and High Contrast. Each produces a distinct aesthetic with a single click.
Can I combine presets with manual adjustments?
Yes. Manual adjustments (brightness, contrast, saturation, hue, blur) stack on top of the selected preset for fine-tuned control.
Is the preview real-time?
Yes. CSS filters are applied to the preview in real-time as you adjust settings. The final render uses Canvas for full-quality output.
Does this reduce image quality?
The output is rendered at the original image resolution with high quality encoding. The only quality changes are from the filters you apply.
Can I undo filter changes?
Yes. Select the Normal preset and reset all sliders to their defaults to return to the original image.
