Based on seller guidance and not confirmed on an official page. Check your seller center.

This page tests a product photo against the Pinduoduo rules we could find, using the real pixels of your file. We could not confirm the figures on an official Pinduoduo page, so treat them as guidance and check your seller account.

Rules a pixel test cannot judge, such as what may appear in the photo, are listed beside the report.

What else to know about Pinduoduo photos

Seller articles describe square carousel images of at least 480 pixels, up to 1 MB.

A white background is advised for the first main image.

Promotional main images may use other sizes (one article cites 750 x 352 under 100 KB), so check your merchant backend.

Questions sellers ask

What size should a Pinduoduo product image be?

Aim for about 800 pixels on the shortest side (our suggestion). The minimum tested here is 480 pixels. These figures come from seller guidance, not an official page, so confirm them in your Pinduoduo account before a large upload.

What shape should a Pinduoduo photo be?

The checker tests for 1:1, based on seller guidance, not an official page. A photo in another shape fails this check, and Fix All pads it on white to reach the shape.

What is the file size limit for Pinduoduo images?

The checker uses 1 MB, based on seller guidance, not an official page. Fix All lowers the JPEG quality first, then the pixel size if it has to, to get under that figure.

Which image formats does Pinduoduo accept?

The checker passes JPEG, PNG, based on seller guidance, not an official page. Fix All exports a JPEG. If your browser cannot open a file, export it as a JPEG from your phone or editor first.

What background does Pinduoduo want on the main image?

In this checker the background is pure white (#FFFFFF), based on seller guidance, not an official page. Fix All does not repaint a background behind your product, so use the background remover if this check fails.

Why did my Pinduoduo photo fail the checker?

The report names the exact rule, such as shape, size, file limit, format or background. Fix All handles shape, size and file limit. A background failure usually needs a new photo in better light or the background remover.

If my photo passes here, will Pinduoduo accept it?

Not necessarily. A pass means the photo meets the rules we can test from pixels. Pinduoduo can apply content rules or change its requirements, so a pass is a useful check and not a promise of acceptance.

Is this Pinduoduo photo checker free, and is my photo uploaded?

It is free and needs no account. Your photo is read by your own browser and never sent to a server. This is an unofficial tool and is not affiliated with Pinduoduo.
