Default uploading image size in Magento 2

by

The question:

I met one strange issue in Magento 2 – I’m trying to change default uploading image size from 800x1200 to 934x1400.

I modified view.xml and now uploaded images going straight to folder media/catalog/product/cache/1/image/934x1400/

<image id="product_page_main_image" type="image">
                <width>934</width>
                <height>1400</height>
</image>
<image id="product_page_main_image_default" type="image">
                <width>934</width>
                <height>1400</height>
</image>
<image id="product_page_image_large" type="image">
                <width>934</width><!-- 800 -->
                <height>1400</height><!-- 1090 -->
</image>
<image id="product_page_image_medium" type="image">
                <width>934</width><!-- 800 -->
                <height>1400</height><!-- 1090 -->
</image>

But their actual size is still 800x1200

Any ideas how to solve this issue? I can’t find any settings to modify default uploading image size.

The Solutions:

Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.

Method 1

There are two ways to change max resizing width & height of the image after uploading:

1) MagentoFrameworkFileUploader.php contain constants MAX_IMAGE_HEIGHT & MAX_IMAGE_WIDTH which is set to 1200 by default

2) magento/module-backend/view/adminhtml/templates/media/uploader.phtml contains PHP code for echo same constants MAX_IMAGE_HEIGHT and MAX_IMAGE_WIDTH. You can just hardcode your value instead these values.

Method 2

Some clarification:

The upload image size limitation is done in multiple area :

Upload images on configurable product creation steps:

vendor/magento/module-configurable-product/view/adminhtml/web/js/variations/steps/bulk.js:317

Upload image for a product

vendor/magento/module-backend/view/adminhtml/templates/media/uploader.phtml:17

Upload image for CMS

vendor/magento/module-cms/view/adminhtml/templates/browser/content/uploader.phtml:103

Abstract class with the constant value

vendor/magento/framework/File/Uploader.php:138

To my mind Magento has not finished to implement correctly this feature because the value is harcoded for the configurable creation.
