Quick answer

The ListingFix Pinduoduo image tool exports a square product photo at 800 x 800 pixels and under 1 MB. Third-party seller articles describe carousel images as square, at least 480 pixels and up to 1 MB. The 800 pixel size is our suggestion, and we found no official Pinduoduo rule page, so confirm in your merchant backend.

What this tool does

Exports an 800 pixel square
Every photo comes out 800 x 800 pixels, our practical choice above the 480 pixel floor in seller articles.
Compresses under 1 MB
Exports a JPEG and lowers quality until the file fits, based on the 1 MB figure seller articles give.
Pad with white or crop
Pad keeps the whole photo and fills gaps with white, while crop fills the frame and trims the edges.
White background retest
Tests each output's outer ring of pixels for white and flags it, since articles advise white on the first image.
Batch and ZIP download
Takes several photos together, then lets you download each one separately or the whole set as a ZIP.

How to use it

1Add your product photo.
2Check the preview in the square frame.
3Download the image and try it in your merchant backend.

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

Seller articles describe Pinduoduo carousel images as square, at least 480 pixels on each side, up to 1 MB, in JPG or PNG. This tool exports an 800 pixel square that fits those numbers.

We could not find Pinduoduo's own rule page, and the articles are from 2022 and 2024. Treat these sizes as a starting point and confirm them in your merchant backend.

Promotional images can differ

One article gives a separate size for activity main images: 750 x 352 pixels under 100 KB. This tool does not make that size. Articles also advise a white background on the first main image, which a resizer cannot create, so start from a photo shot on white.

Questions sellers ask

What size should a Pinduoduo product image be?

Seller articles describe carousel images as square, at least 480 pixels on each side, up to 1 MB, in JPG or PNG. This tool exports 800 x 800 pixels, which is our own suggestion. We found no official rule page, so check your merchant backend.

Are these official Pinduoduo image rules?

No. We could not find Pinduoduo's own rules, so these figures come from third-party seller articles published in 2022 and 2024. Rules can change. Check the rule center in your merchant backend before you prepare a whole catalog at this size.

Why does the tool export 800 pixels?

The articles give 480 pixels as a floor, and 800 pixels clears it with more detail for buyers on larger phones. The 800 figure is our practical choice rather than a Pinduoduo number. Your backend will show whether it needs something different.

Why keep a Pinduoduo image under 1 MB?

Seller articles say carousel images should be 1 MB or smaller, in JPG or PNG. We could not confirm this on a Pinduoduo page. Keeping the file under that figure is a low-risk choice, and an 800 pixel JPEG usually fits comfortably.

Does a Pinduoduo main image need a white background?

Seller articles advise a white background on the first main image, though we could not confirm this on a Pinduoduo page. This tool can pad with white but cannot repaint a background, and it flags an output whose edges are not white. Start from a photo shot on white.

Can this tool make a 750 x 352 Pinduoduo promotional image?

No. One article cites 750 x 352 pixels under 100 KB for activity main images, and this tool does not make that size. It only exports the 800 pixel square. Check your merchant backend for what a particular promotion actually asks for.

Should I pad or crop a photo for Pinduoduo?

Pad when the whole product must show, because it keeps the full photo and adds white at the sides. Crop when there is spare background around the product, since it fills the frame by trimming the edges. Check the after preview either way.

Why did my Pinduoduo photo get a warning after resizing?

The tool retests each output against the seller guidance we hold. A failed background test is a common result, because resizing cannot repaint a background. The result lists exactly which test missed, so you can reshoot on white or use a background remover, then resize again.

Is my photo sent to a server when I use this Pinduoduo tool?

No. Your browser does the work on your own device, and the site has no server that receives images, so nothing is sent to us or to a third party. The tool is free and you can use it without creating an account.
