What is the difference between a 'Main Filter' and 'Adjustments'?

A 'Main Filter' (like Sepia or Grayscale) applies a distinct stylistic effect to the image. 'Adjustments' (like Brightness, Contrast, Hue Rotate, Saturation, Blur) are global modifications that fine-tune the image's appearance and can be used alone or in combination with a Main Filter.

How does the 'Threshold' filter work?

The Threshold filter converts the image to a stark black and white. Pixels brighter than the 'Threshold Level' (adjustable from 0 to 255) become white, and pixels darker or equal become black. It's great for creating high-contrast, graphic effects, especially on grayscale images.

Can I use these image filters for Instagram or other social media?

Yes, absolutely! This online image filter tool is perfect for quickly adding creative touches or enhancing your photos before posting them on Instagram, Facebook, Twitter, or any other social media platform.

Is this image filter editor completely free?

Yes, our Image Filters & Adjustments tool is free to use online. You can apply various filters and adjustments to your photos without any cost or limitations.

Will applying filters and adjustments reduce the quality of my image?

The filters and adjustments are applied using a combination of CSS canvas filters and pixel manipulations. While the goal is to maintain quality, some complex operations or re-saving in lossy formats (like JPEG if chosen for download) can introduce minor changes. The original uploaded image remains unaffected. For pixel-perfect preservation, PNG output is often best.

What do Hue Rotate and Saturation adjustments do?

'Hue Rotate' shifts all the colors in your image around the color wheel, measured in degrees (0-360). This can create psychedelic or artistic color changes. 'Saturation' adjusts the intensity of colors. Negative values desaturate (move towards grayscale), while positive values make colors more vibrant.
