- Short answer
- Yes for WebP — one of nine accepted product image types; no upload list we read names AVIF, served only where a browser supports it.
- AVIF on upload
- No accepted-file-type list we read on September 8, 2026 names AVIF — only delivery does.
- Collection images
- WebP is refused for a collection image, even though products and Files accept it.
- Delivery depends on the browser
- WebP or AVIF reach the shopper only where the browser supports them; Shopify picks per client.
- Other upload surfaces
- Theme uploads convert PSD, TIFF and BMP to JPEG or PNG; Content > Files accepts five image formats.
- As of
- Shopify Help Center product media, add-media, Files and theme image pages plus shopify.dev image_url, read September 8, 2026.
Does Shopify accept WebP for product images?
Yes. Shopify names PNG as the best type for most product images, JPEG next, and then lists the rest: "Other accepted file types are PSD, TIFF, BMP, GIF, SVG, HEIC, and WebP". That is nine types in total, and animated GIF and WebP files are supported as well.
Two other limits ride on the same upload: a product or collection image must be under 20 MB and no larger than 5000 x 5000 px, or 25 megapixels.
Can you upload an AVIF file to Shopify?
Not according to Shopify's own file-type lists. None of the accepted-file-type lists we read on September 8, 2026 names AVIF — not on the product media types page, theme images, Content > Files, add-media, or shopify.dev's image_url reference.
Yet a shopper can still receive AVIF where the browser supports it: the conversion happens on delivery, not on upload.
Shopify automatically detects which image formats are supported by the client (e.g. WebP, AVIF, etc.) and selects a file format for optimal quality and file size.
So converting your library to AVIF before upload buys nothing: those lists don't name it, and Shopify already picks that format per browser. The file's size and dimensions are still yours.
Where does WebP get refused?
As a collection image. Shopify says so outright: "Collection images don't support WebP, even though products and Files do". So the same file can sit on a product and be refused as the collection image above it.
Two other surfaces accept WebP but publish their own shorter lists.
- Theme editor — JPEG, Progressive JPEG, PNG, GIF, HEIC and WebP; PSD, TIFF and BMP are converted to JPEG or PNG on upload.
- Content > Files — five types: JPEG, PNG, WEBP, HEIC and GIF. Uploads there and product media draw on one file storage pool.
