Shopify Image Megapixel Calculator
Calculate megapixels, file-size risk, and upload readiness for Shopify product, banner, and theme image files.
Megapixel report
5000×5000px is 25MP and 18MB. Shopify: megapixel too high, file size ok.
- danger 25MP vs limit 20MP.
- safe 18MB vs limit 20MB.
- A file can be under the MB limit and still fail if the megapixel count is too high.
How to use this result
Start with the target surface: a printed size, a platform canvas, a marketplace image requirement, or a safe-zone overlay. Enter the real pixel dimensions or upload a local image when the tool supports it, then compare the result with the recommended size, ratio, file-size limit, and source note.
Use the copied output as a production checklist rather than as an approval guarantee. The calculator checks measurable dimensions and ratios, while final acceptance can still depend on compression, color, account settings, crop previews, platform policy, or printer-specific export instructions.
