About Sepia Photo Filter
The sepia matrix used here is the long-standing Microsoft one: red becomes 0.393R + 0.769G + 0.189B, with slightly different weights for green and blue. It is a warm-toned desaturation rather than a simple tint, which is why it looks like aged photographic paper instead of a brown filter laid over the top.

Questions
What does the strength slider do?
It blends between the original and the fully transformed pixel. At 40–60% you get a subtle warm cast that keeps some color; at 100% you get the classic full sepia.
Which file types can I use?
JPG, PNG, WEBP, GIF, BMP, AVIF and SVG — anything your browser can display. Because decoding is handled by your browser rather than a conversion server, support tracks whatever your browser can already open.
Is there a file size limit?
No imposed limit — there is no server quota to hit. The real ceiling is your device's memory, since the whole file is held in RAM while it is processed. Desktop browsers cope with very large files; phones give up sooner.
What are the limits on strength?
It accepts 0 to 100%, starting at 100%.
