 ## Fault-Tolerant Decoding for Other Formats
 
 In addition to JPEG, @cross/image provides fault-tolerant decoding for several other formats that

+### QOI (Quite OK Image)
+
+Fast lossless format with simple encoding.
+
+```ts
+import { Image } from "jsr:@cross/image";

+const data = await Deno.readFile("input.png");

+### PGM (Portable GrayMap)
+
+Netpbm grayscale format; RGB is converted to grayscale using luma weighting.
+
+```ts
+import { Image } from "jsr:@cross/image";
+
+const data = await Deno.readFile("input.png");
+const image = await Image.decode(data);

+// Encode as PGM (binary P5 format)
+const pgm = await image.encode("pgm");
+await Deno.writeFile("output.pgm", pgm);
+```
+
+### PBM (Portable BitMap)
+
+Netpbm monochrome format; pixels at or above luma 128 become white.
+
+```ts
+import { Image } from "jsr:@cross/image";
+
+const data = await Deno.readFile("input.png");
