Does this optimize images for Shopify automatically?
It handles practical storefront prep in the browser: framing, format choice, lighter output, canvas background tone, and optional watermarking. It does not claim server-side Shopify-specific automation.
Can I still export JPG or PNG instead of WebP?
Yes. This page starts from Shopify-style defaults, but the export format can still be changed inside the same root tool UI.
Is the product image uploaded to a server?
No. The image stays local while the browser renders the preview and export, and the saved file is rebuilt from canvas with common metadata stripped on save.
What are Shopify's product image limits?
Up to 20 megapixels and up to 20 MB per image. Shopify recommends square images around 2048 x 2048 pixels so the product-page zoom stays sharp.
Should I upload WebP to Shopify?
You can, but it changes less than people expect. Shopify's CDN automatically converts and serves WebP or AVIF to browsers that support them, whatever you upload. Exporting WebP saves you upload bandwidth; it does not change the format shoppers receive.
Does compressing images actually speed up a Shopify store?
Yes, but the win is mostly in what the theme requests, not in the source file. Shopify serves resized derivatives, so a 20 MB original is not sent to shoppers. The real gains come from fewer images above the fold and correct image sizing in the theme.
Square or portrait for Shopify products?
Match your theme. Most themes crop product cards to a fixed ratio, so if the theme is square and your images are 4:5, the cards will be cropped top and bottom. Pick one ratio and use it for the whole catalogue.
Why does this page open on WebP at 0.8 quality?
It is the lightweight-upload workflow: WebP at 0.8 is roughly 25 to 35 percent smaller than a comparable JPEG for the same visual quality, which matters when you are uploading hundreds of images. Switch to JPG if a downstream app or feed does not accept WebP.
