How it works
- ● Applies a standard sepia matrix to every pixel's RGB channels.
- ● The intensity slider blends between original and full sepia.
- ● Output is baked into the image — no runtime filter needed.
- ● All processing happens locally in your browser.
The sepia matrix
The classic sepia transformation maps each pixel using these coefficients:
R' = 0.393R + 0.769G + 0.189B
G' = 0.349R + 0.686G + 0.168B
B' = 0.272R + 0.534G + 0.131B
Values are clamped to 255. This mimics the chemical toning used in traditional darkroom printing.
Warm vintage tones, zero uploads
Our sepia filter uses the same matrix transformation found in professional photo-editing software. The intensity control lets you dial in anything from a subtle warm tint to a full old-world photographic look. Everything runs on your device — your images never leave the browser.

Frequently Asked Questions
What is a sepia filter?
A sepia filter applies a warm, brownish tone to an image, mimicking the look of early photographic prints. It works by remapping each pixel's RGB values through a matrix that boosts red and green channels while reducing blue, producing the characteristic warm cast associated with vintage photography.
How do I create a vintage look?
Apply the sepia filter and combine it with reduced contrast or a slight vignette effect. Lowering the intensity slider gives a subtle warm tint, while higher values produce a more dramatic old-photo aesthetic. Pair with desaturation beforehand for an even more authentic vintage feel.
Can I adjust sepia intensity?
Yes. The intensity slider lets you blend between the original image and the full sepia effect. At 0% you get the original image, at 100% you get a complete sepia tone, and anything in between gives you partial warm tinting.
