For Walmart sellers
Photo resizing for Walmart sellers
Drop your product photos, pick the Walmart preset, and get back a ZIP sized to Walmart's own rules. No account for the free pack, and your photos never leave your browser.
Why this is slower than it should be
- ·Walmart's image guidance asks for a square image on a seamless white background (RGB 255, 255, 255), with the product kept off the frame edge on white background shots.
- ·A file over Walmart's size limit fails the submission, so oversized originals have to be shrunk before they are uploaded.
- ·Sellers with many items need every main image at the same size, not resized one at a time.

Walmart main image size (2200×2200px) quotes Walmart's own words, dated, with the size SizeSpec outputs for it.
Questions
What are Walmart's main image requirements?
See the full, sourced answer in the Walmart main image requirements guide, including the size, the file size limit and the background rule, and the note about which Walmart page the figures come from.
Can I process many product photos in one go?
Yes. Drop the batch in, pick the Walmart main image preset, and download one ZIP with every photo at the same spec.
Are my product photos uploaded to SizeSpec's servers?
No. Resizing happens in your browser; photos are never uploaded.
