Shopify Image Maxxxer
Drop an image and it gets resized to fit Shopify's upload limits, then downloads straight away. Everything runs locally in your browser.
What it's for
Shopify accepts product images up to 20 megapixels, 4472×4472 pixels and 20 MB per file. Send anything bigger and the platform handles the resizing at upload — not always in the way you'd choose. This tool puts you in control: it scales the image down cleanly, re-encodes it under the size cap, and hands you back a file you know will upload first time.
- PNG and WebP stay PNG and WebP; anything else is encoded as JPEG at 92% quality.
- Files already within the limits pass through untouched.
- The download is named
filename-maxxed.extso you can tell it apart from the original.
Why it's safe to use
There's no server on the other end. The image is read, resized and encoded entirely by your browser — nothing is uploaded, stored or logged anywhere. Close the tab and it's gone.
