About the RAW to PNG Converter

Turn a headerless RAW pixel dump into a PNG you can open anywhere. A RAW file has no width, height or color layout stored in it, so you enter those and the tool decodes the bytes in your browser, shows the picture and lets you download a lossless PNG.

Key Features

Decodes RGBA, RGB, BGRA and 8-bit grayscale byte layouts
Checks width x height x bytes per pixel against the real file size
Suggests every landscape size that exactly fits your file
Shows the decoded image on a transparency checkerboard
Downloads a lossless PNG with the alpha channel intact
Reads the file locally with no upload and no account

Use Cases

Inspecting a framebuffer dump from an embedded display or Raspberry Pi camera
Checking a texture or render target exported from a game engine or OpenGL readback
Verifying the output of a C, Rust or Python image pipeline against what you expected
Recovering a picture from a headerless .raw or .bin capture when the size is only half remembered
Round-tripping files made by a PNG to RAW converter to confirm the byte order

Supported Formats

RGBA

RGB

BGRA

Grayscale (8-bit)

How do I know the width and height of a RAW file?

A RAW pixel file stores only pixel values, so the dimensions are not in the file. Multiply width by height by bytes per pixel and the result must equal the file size in bytes: a 1920 x 1080 RGBA file is exactly 8,294,400 bytes. If you only know the size, pick the pixel format first and use the suggested dimensions, which list every landscape size that divides evenly. A wrong width produces a sheared, diagonal picture, which is the quickest sign to try another size.

Your file stays on your device

The bytes are decoded by your browser's canvas. Nothing is sent to a server.
