Questions
What makes a sepia tone look the way it does?
The classic sepia matrix maps each pixel's red, green and blue channels to new values using fixed coefficients that shift the palette towards warm brown tones, mimicking the silver-sulphide toning process used in early photography.
Does saving as JPEG lose quality?
JPEG uses lossy compression, so some fine detail may be lost depending on the quality setting. For a lossless result choose PNG. WebP offers a good balance between file size and quality.
Will EXIF or other metadata be kept?
The filter re-encodes the image through the browser canvas, which drops EXIF and other embedded metadata. Keep a copy of the original if metadata matters.
Is the image sent anywhere?
No. All processing runs entirely inside your browser. Your file never leaves your device.
More image tools
ICO Converter
Build a multi-size .ico file from a PNG or JPG, choosing which pixel sizes to include — ideal for application icons and browser favicons.
Favicon Generator
Generate a full favicon set from one image: a three-size ICO, an Apple touch icon, PWA icons, a webmanifest, and the HTML.
SVG Converter
Rasterize an SVG file to PNG, JPEG or WebP at a scale factor you choose. The result is a pixel image — not editable vector paths.
SVG to JPG
Convert an SVG to a JPEG image at the export scale you set, composited onto a solid background colour — because JPEG has no transparency.
Adjust Brightness
Lighten or darken an image by shifting every pixel's brightness up or down with a single slider.
Adjust Contrast
Increase or reduce the difference between light and dark areas to make an image pop or flatten it.
Adjust Saturation
Boost or reduce the intensity of colours in an image, all the way from vivid to greyscale.
Rotate Hue
Shift every colour in an image around the hue wheel to change the overall colour cast.
