Sepia replaces an image's colours with warm brown tones reminiscent of antique photographs. This tool uses the classic sepia matrix: each output channel is a fixed blend of the original red, green and blue (for example the new red is about 0.39 red + 0.77 green + 0.19 blue), which produces the familiar aged, sun-warmed brown rather than a flat tint over gray.
A sepia tone is a quick way to give photos a nostalgic, timeless feel, to unify a set of images under one warm palette, or to soften a harsh snapshot. The output keeps your original format and dimensions - a PNG stays a PNG (transparency preserved), a JPEG stays a JPEG - so it slots straight back into your layout.
Everything runs entirely locally in your browser on a canvas (no upload, even offline) - your image never leaves your device. The effect is a fixed per-pixel matrix, so it is exact and repeatable. Animated images are flattened to a single frame; for plain black and white use the grayscale tool instead.

Limitations: Applies the classic sepia matrix per pixel to give a warm brown vintage tone; alpha is kept. The original format and dimensions are preserved (PNG keeps transparency; JPEG flattens onto white). Animated inputs are reduced to a single frame. It is a fixed transform with no settings.
No. The effect runs entirely locally in the browser on a canvas - even offline. Your image never leaves your device.
Grayscale removes all colour; sepia replaces it with a warm brown palette via a fixed matrix, for an aged-photo look rather than neutral gray.
Yes. A PNG stays a PNG with its transparency; a JPEG stays a JPEG (flattened onto white). Dimensions are unchanged.
No. Sepia blends the colour channels and cannot be reversed exactly, so keep your original if you need it back.
