File to C Array Converter

Select a file:

File info

This section contains basic information on the uploaded file.
If it is an image, the size in pixel and a preview will be shown

Name

Size

Type

Last modified

Preview

The grey border around the image is for visibility only.
If it is shorter than 32px, or taller than 100px, it will be resized. Again, for visibility reasons.

Conversion settings

Code format

The array declaration will contain bytes in this format.
So if you have choosen "Hex (0x00)", it will give you this output:

static const unsigned char awesomeimage[] = {
  0x00, 0xff, 0xff
};

Treat as binary

This tells the converter to treat the current file as a binary, eventhough it is an image.
Every image conversion option will be disabled.
Also will exclude the widht and height info from the output.

Palette mod

This controls the output palette format of the image
For more info on this, please see the WikiPedia aricle on color depth

Resize

Fill only one of the size boxes to resize the image maintaining the original spect ratio.
Keep both empty, if you do not want to change the size.

x (Fill only one to maintain aspect ratio)

Multi line

The bytes in the array will be split into multiple lines, roughly matching the aspect ratio of the image.
Unselect this to have all the bytes in a single row.

Optimize for column read

For applications where you need to display the image one 8bit column at a time - as opposed to the normal mode where you plot the image by row.
Row read optimized:

Column read optimized:

This is only available in 1bit mode!

Separate bytes of pixels

If ticked every byte of every pixel will be added to the array separately. Otherwise one item in the array will represent all bytes of one pixel.

Endianness

static

const

unsigned

Data type

PROGMEM

These control the signature generated.
Please note, not all of them make sense in all languages!
