Frequently Asked Questions

Common questions about Merchlint – Product Image Size Checker for Google Merchant Center

It is a warning in Google Merchant Center: the image of this offer is smaller than 500 × 500 pixels, the minimum Google applies to all products from 31 January 2027. Until then the old minimum applies: 100 × 100 pixels, or 250 × 250 for clothing. The rules are on Google's help page for the image_link attribute.

It can, but only after the products have been sent to Google. Google for WooCommerce lists the

Product Feed page. Before sending, it checks that the image link is valid, not how large the image is. If there is any error in that list, for any product or for the account, the card shows only the errors, and warnings like this one are not listed. This plugin gives you the list before anything is sent: which image it is (main, gallery, or variation), its size, and a larger original if there is one. This describes Google for WooCommerce 3.9.6.

Not necessarily. Google says it will optimize some images smaller than 500 × 500 automatically, and it does not say which. A listed image may be rejected or replaced with an enlarged copy. Images under 100 × 100 px are rejected already today; the plugin marks them separately. My original image is large, but Merchant Center still says it is too small. The plugin checks the full-size file. Some feed plugins let you choose which image size goes into the feed; if yours sends a smaller size, Google gets that smaller image. Set the feed to the full size.

Images whose file is not on this server (for example images offloaded to S3 or a CDN), empty files, and formats whose size PHP cannot read (SVG, or AVIF on older PHP). They are listed as "Not checked" with the reason, instead of being guessed. Drafts and private products are not checked: they do not go to Google.

The plugin does not do it, and it does not help: an enlarged small picture gets bigger, not sharper. Use a larger original or a new photo. Google recommends about 1500 × 1500 pixels.

No. It reads products and image files and never writes to them. It stores the last result in one option, and up to three marks per user that keep closed things closed: the notice on the Plugins screen, the box about Merchlint, and the review request. Deleting the plugin removes the option and all the marks, on every site of a network.
