Image Filter & Color Adjuster

What is Image Filter & Color Adjuster?

The deftdeck Image Filter is a free online photo filter and color-correction tool that runs entirely in your browser. Photographers, designers, social-media creators, and bloggers can drop in any image their browser can open (such as PNG, JPEG, or WebP) and fine-tune it with eight independent controls: Brightness, Contrast, Saturation, Hue, Grayscale, Sepia, Invert, and Blur. Drag each slider or type an exact value into the number box and the preview re-renders automatically, so you can dial in a vintage sepia look, a high-contrast black-and-white, a color shift, or a soft blur without leaving the page. A live before-and-after preview lets you click either image to zoom in, and a Reset filters button instantly restores the original look. The filtered image keeps its original JPEG or WebP format (anything else, such as PNG, is exported as PNG) and downloads with a -filtered suffix.

How to use Image Filter & Color Adjuster

1. Drag and drop an image onto the dropzone, or click it to pick a file (PNG, JPEG, WebP, or any other image your browser can open) from your device.
2. Adjust the Brightness, Contrast, and Saturation sliders (100% is the original); the result preview re-renders automatically as you change them.
3. Shift colors with Hue, or stylize with Grayscale, Sepia, and Invert (0% means the effect is off).
4. Drag the Blur slider for a soft-focus effect, or type an exact value into any number box for precise control.
5. Compare the Original and Filtered previews side by side (click either one to open the zoom lightbox), and use Reset filters to return to the original.
6. Click Download to save the adjusted image, named with a -filtered suffix in its original format.

Frequently asked questions

Which adjustments can I make?

Eight independent filters: Brightness, Contrast, and Saturation (percent, 100% = original), Hue rotation (degrees), and Grayscale, Sepia, Invert, and Blur. You can combine any of them, and each slider has a matching number box for exact values.

What image formats are supported?

Any image your browser can open (the dropzone accepts image/*), including PNG, JPEG, and WebP. The result keeps the original format if it was JPEG or WebP; everything else, such as PNG, is exported as PNG.

Does the preview update as I change a slider?

Yes. Whenever you move a slider or type a new value, the tool re-renders the image automatically after a brief pause, so the Filtered preview always reflects your current settings without clicking a button.

How do I undo my changes?

Click Reset filters to return every control to its original value (no effect applied), or use Clear to remove the image entirely and start over with a new one.

Are my images uploaded to a server?

No. Everything runs 100% client-side in your browser using the HTML canvas filter. Your image is never uploaded to deftdeck or any server, and nothing leaves your device.
