# Convert Raw Pixel Buffer to PNG

Convert a headerless raw pixel buffer file to a PNG image. You must provide the image dimensions, channel count, and bit depth.

## Overview

Use this tool when you need to preview or export a headerless raw pixel buffer as a PNG image. It does not parse photographic camera RAW containers such as DNG, ARW, CR2, or NEF. The conversion is only correct when the width, height, channel count, and bit depth you enter exactly match the source buffer.

## Inputs

- **Raw Pixel Buffer File** (file): Select raw pixel buffer file to convert
- **Image Width (pixels)** (text): Enter image width in pixels
- **Image Height (pixels)** (text): Enter image height in pixels
- **Color Channels** (select): Select number of color channels
- **Input Bit Depth** (select): Select bit depth of raw data
- **PNG Compression Level** (select): Select compression level (0-9)

## When to use

- When you need to visualize raw frame buffers generated by custom camera sensors or embedded systems.
- When debugging graphics rendering pipelines that output raw, headerless pixel arrays.
- When converting uncompressed binary image data into a standard, shareable PNG format.

## How it works

- Upload the headerless raw pixel buffer file containing the binary image data.
- Specify the exact width, height, number of color channels (1 to 4), and bit depth (8-bit or 16-bit) of the source buffer.
- Select the desired PNG compression level to balance processing speed and output file size.
- Click convert to process the binary stream and download the rendered PNG image.

## Use cases

- Visualizing raw sensor data from embedded camera modules during hardware development.
- Converting raw GPU frame buffer dumps into viewable PNG images for debugging.
- Reconstructing images from custom binary datasets used in machine learning pipelines.

## Frequently asked questions

### Does this tool support camera RAW formats like CR2, NEF, or DNG?

No, this tool only converts headerless raw pixel buffers and does not parse photographic camera RAW containers.

### What happens if I enter the wrong image dimensions?

The output image will appear skewed, scrambled, or fail to render because the binary data alignment depends on exact dimensions.

### Which color channel configurations are supported?

You can choose between 1 (Grayscale), 2 (Grayscale + Alpha), 3 (RGB), and 4 (RGBA) channels.

### Can I convert 16-bit raw pixel buffers?

Yes, the tool supports both 8-bit and 16-bit depth configurations per channel.

### Does the compression level affect the quality of the output PNG?

No, PNG uses lossless compression. Changing the compression level only affects the file size and processing time, not the image quality.
