WP creates unnecessary "cropped-"[filename] icon file

When you setup web icon, it always creates "cropped-"[filename] icon file, even when you upload precisely 512×512 png file, so that the new file is exact copy.

(and btw it is not optimal that for icon you have to go to customizer and for logo you have to go to site editor. IMO both should be logically defined on options-general.php admin screen, where is the site title and description and then as a block in site editor you could change the logo as well).

Thanks for the report!

I found some further weirdness in my testing. If you remove the icon using the remove button and select the source 512x512 image again, it makes ANOTHER copy. You can repeat this process a bunch of times and each will result in another cropped copy made.

@joedolson mentioned :
Two things: 1) should be able to skip cropping if the image has the right dimensions, 2) should only create a cropped version once.

Moving to 6.3 to keep visibility on this and work toward a resolution.

I have opened a pull request that addresses the cropping issue when uploading an image with the correct dimensions. However, I am unable to replicate the problem of multiple cropping. Is it possible that the issue has already been resolved?

@antpb Are there any steps other than removing/uploading a new icon?

Comment has no sense because we know for sure that this is $context === 'site-icon':

// Skip creating a new attachment if the attachment is a Site Icon.

This line is not working because _wp_attachment_context doesn't exist at this point:

get_post_meta( $attachment_id, '_wp_attachment_context', true ) == $context

And this condition is now working either became there is no $metadata array:

$data['width'] === $metadata['width'] && $data['height'] === $metadata['height']

So, it needs to check something else to make this work.

Hey, I am kinda new to this whole "contributing thing". So, I have no idea if this is the best way to contribute, yet, I was struggling with a similar issue with SVG instead of ICO files and wanted to share it here.

  1. I added SVG support and wanted to upload a .svg file as the Site Icon (Appearance >> Customize >> Site Identity).
  2. I uploaded the .svg first. That went well since I had enabled SVG support inside functions.php.
  3. I wanted to select the uploaded .svg as a Site Icon. I selected the image, but WP asked me to crop the image. I could not do that since WP is not set up to crop vector images. I clicked on "Crop" anyway and WP gave me an error, that the image can't be cropped. Suprise, surprise...

To fix the issue, I added the following code in the same file /wp-admin/includes/ajax-actions.php

function wp_ajax_crop_image() {

// of the code

if ( empty( $attachment_id ) || ! current_user_can( 'edit_post', $attachment_id ) ) {


// Check if the attachment is an SVG file
    $mime_type = get_post_mime_type( $attachment_id );
    if ( 'image/svg+xml' === $mime_type ) {
        // For SVG files, send the original image data without cropping
        wp_send_json_success( wp_prepare_attachment_for_js( $attachment_id ) );


$context = str_replace( '_', '-', $_POST['context'] );
$data    = array_map( 'absint', $_POST['cropDetails'] );
$cropped = wp_crop_image( $attachment_id, $data['x1'], $data['y1'], $data['width'], $data['height'], $data['dst_width'], $data['dst_height'] );

// of the code

What it does, is it checks if the image that is going to be cropped is an SVG, if it is and you click on "Crop" it does not bother to crop it at all and returns the image as it is.

This way I was able to designate the SVG file I uploaded as a Site Icon.

I am not saying that this is a perfect solution, but I do not see the point in cropping an SVG at all. So it works for me...
