Convert to 3:4

What it is

Ozon and Wildberries show vertical 3:4 cards larger than square ones. Since February 2025 Ozon has been moving product cards to 3:4 photos: square photos get white bars above and below in search results. If you have many old 1:1 cards, you don't need to remake them: upload a batch and Sozdai converts it to 3:4.

Nothing is cropped: the AI rebuilds the card in the vertical format the way a designer would — the same product, the same text, the same style, with the blocks spread over the height. Before converting, the AI copies all text from the card word for word and carries it over unchanged. The product and lettering are redrawn, though, so check the result before uploading it to the marketplace.

Open it with "Convert to 3:4" in the top menu (on a phone — in the ☰ menu) or the button of the same name above the project list.

You can try it without signing up on the "3:4 photos for Ozon" page: one card is converted there for free.

How to use it

1. Drop images into the frame, or click it and choose files. JPG, PNG and WEBP up to 20 MB, up to 50 per batch. Cards of different products can be mixed — no project is needed.
2. Click "Convert N images · M 💎". The price is on the button, and the whole batch is charged at once.
3. You can leave the page — the batch finishes on its own. One image takes about half a minute; three images in a batch run at the same time.

Price

2 💎 per image.

• If an image fails, its credits come back automatically — the tile says "Failed · 2 💎 returned".
• "Try again · 2 💎" under a finished image is a new generation and costs the same. The first click asks for confirmation ("Spend 2 💎?"), the second one redoes the image. While another batch is running, you can't redo an image from an older batch — wait until that batch finishes.
• Until you've paid for anything, results carry the sozdai.app watermark, like other images (see Credits).

"Already fits"

An image that is already 3:4 or taller is marked "Already fits" and isn't converted — no credits are charged for it.

Images smaller than 400 px on the short side and images wider than 2:1 aren't accepted.

Result size

The width matches the original, but not less than 900 px (Ozon's recommendation) and not more than 2000 px. The height is 4/3 of the width: for example, 1200×1200 → 1200×1600. JPG stays JPG; PNG and WEBP are saved as PNG.

Download

• "Download" under an image — one file.
• "Download all (ZIP)" — all finished images of the batch. Files in the archive are named after your originals with a _3x4 suffix, so it's easy to tell which card belongs to which product.
• Click an image to open the "Before / After" comparison.

History

Below the work area is "Previous batches": the date, the number of images and how many are ready. Click a batch to open it, download the results or redo a single image. "New batch" takes you back to uploading.

Batches don't appear in the project list — they live only on this page.
