Image Filter, Presets & LUT Color Grading

What is Image Filter, Presets & LUT Color Grading?

The deftdeck Image Filter is a free online photo filter and color-grading tool that runs entirely in your browser. Tap a one-click preset (None, Vintage, Warm, Cool, B&W, High contrast, Fade, Cinematic) for an instant look, or build your own with eight CSS filter sliders: Brightness, Contrast, Saturation, Hue, Grayscale, Sepia, Invert and Blur. Advanced controls add per-pixel Temperature and Tint (white balance), Sharpen and Vignette, and you can import a .cube 3D LUT to reproduce a grade from your video or photo editor. A draggable before/after slider compares the original with the filtered result, and the output keeps its original JPEG or WebP format (anything else is exported as PNG) with a -filtered suffix. Everything, including the LUT, is processed locally and nothing is uploaded.

How to use Image Filter, Presets & LUT Color Grading

1. Drag and drop an image onto the dropzone, or click it to pick a file (PNG, JPEG, WebP, or any image your browser can open).
2. Tap a preset such as Vintage, Warm, Cool, B&W, High contrast, Fade or Cinematic for an instant look, or leave it on None to start clean.
3. Open Adjustments (the gear) to fine-tune Brightness, Contrast, Saturation, Hue, Grayscale, Sepia, Invert and Blur, plus Temperature, Tint, Sharpen and Vignette.
4. Optionally click Import LUT to load a .cube 3D LUT for custom color grading; use Remove to drop it again.
5. Drag the before/after slider to compare the original against the filtered result, and click the result to zoom in.
6. Click Download to save the image (original format, -filtered suffix), or Reset filters to return every control to neutral.

Examples

Frequently asked questions

What presets are included?

None, Vintage, Warm, Cool, B&W, High contrast, Fade and Cinematic. Each preset simply sets the sliders, so you can apply one and then fine-tune every value afterward.

What do Temperature, Tint, Sharpen and Vignette do?

They are per-pixel adjustments applied on top of the CSS filters: Temperature and Tint shift the white balance (warm/cool and green/magenta), Sharpen applies an unsharp mask, and Vignette darkens the edges.

Can I use my own LUT?

Yes. Import a 3D .cube LUT file and it is applied with trilinear interpolation for custom color grading. 1D LUTs are not supported, and the file is read only in your browser.

What is the before/after slider?

A draggable divider over the preview: one side shows the original image and the other shows the filtered result, so you can judge the effect at any split position.

Are my images or LUTs uploaded to a server?

No. Everything (filters, presets, LUTs and grading) runs 100% client-side in your browser. Your image and .cube file are never uploaded to deftdeck or any server.
