I’m a novice programmer trying to create an image uploader for my personal website. I’m using the libpng library to handle the PNG format images that I want to display. However, I’ve run into an issue with the “ICCP known incorrect sRGB profile” warning message popping up whenever I try to upload my images. I have no idea what this warning means or how to resolve it.
Here’s a portion of my code:
void read_png_file(char* file_name) {
png_byte header[8];
FILE *fp = fopen(file_name, "rb");
if (!fp) {
printf("[read_png_file] File %s could not be opened for reading", file_name);
return;
}
fread(header, 1, 8, fp);
if (png_sig_cmp(header, 0, 8)) {
printf("[read_png_file] File %s is not a valid PNG image", file_name);
return;
}
png_structp png_ptr = png_create_read_struct(PNG_LIBPNG_VER_STRING, NULL, NULL, NULL);
if (!png_ptr) {
printf("[read_png_file] png_create_read_struct failed");
return;
}
png_infop info_ptr = png_create_info_struct(png_ptr);
if (!info_ptr) {
printf("[read_png_file] png_create_info_struct failed");
return;
}
if (setjmp(png_jmpbuf(png_ptr))) {
printf("[read_png_file] Error during init_io");
return;
}
png_init_io(png_ptr, fp);
png_set_sig_bytes(png_ptr, 8);
png_read_info(png_ptr, info_ptr);
int width = png_get_image_width(png_ptr, info_ptr);
Could someone please help me understand what an “ICCP known incorrect sRGB profile” warning message means and how I can resolve it? Any help or direction would be greatly appreciated.

The error “libpng warning iccp known incorrect sRGB profile” usually occurs when an image has an incorrect profile. To resolve this issue, open the image using a photo editing software and make sure it is saved without any color profile or with a proper sRGB color profile.
See lessSometimes this error is also generated because the image is missing a profile, so to fix this, you can set the color profile of your image before saving it. This can be done using a photo editing software or command-line tools like ImageMagick.
In my personal experience, I had encountered this error while working on a web project. I had to make sure that all the images used on my website were optimized and saved with the correct color profile. This helps in reducing the page load time while maintaining the color quality of the images.
To troubleshoot this error, it is also recommended to check if your code is properly handling the image files and loading them in the correct format. Sometimes, the issue may not be with the image itself but with the way it is being processed and loaded. By following these steps and practices, you can avoid this error and ensure that all the images on your website or application are displayed correctly.
