Qoo10 and Carousell Image Size Guide for Singapore Sellers (2026)

If you sell in Singapore, chances are you are not on just one platform. Many sellers run a Shopee or Lazada store, list the same stock on Qoo10, and clear older items or one-offs on Carousell. Each platform shows your photos differently, and a picture that looks sharp on one can come out cropped, soft or oddly framed on another.

This guide covers the image sizes and habits that work on Qoo10 and Carousell in 2026, how the two platforms differ, and how to prepare one set of photos that works on both without editing every file twice.

Why Qoo10 and Carousell need different thinking

Qoo10 and Carousell attract different buyers and display photos in different ways.

• Qoo10 is a marketplace built around deals and price comparison. Shoppers scroll grids of square thumbnails, often on a phone, and decide in a second or two which listing to tap. Your main image competes directly with dozens of near-identical products.
• Carousell is a classifieds-style marketplace. Many buyers are looking for a specific item, often second-hand, and they look closely at condition, authenticity and what is included. Real photos matter more than polished studio shots.

So on Qoo10 you are trying to win the thumbnail. On Carousell you are trying to win trust.

Qoo10 image sizes: what to upload

Qoo10 does not publish one clear image spec sheet in English, and the limits in the seller tool (QSM) have changed over the years. The safest approach is to export to a size that is well above any minimum and well below any file size limit you might hit.

Main (thumbnail) image

• Shape: square, 1:1. Qoo10 search results and category pages show square thumbnails, so a non-square image will be letterboxed or cropped.
• Size: 1000 x 1000 pixels is a sensible target. It is sharp on high-density phone screens and leaves room for zoom, without making the upload heavy.
• Format: JPG for photos. Use PNG only if you need sharp text or flat graphics.
• File size: aim for under 1 MB per image. Most product photos at 1000 x 1000 pixels come in at 150 to 400 KB at a JPG quality of around 80 to 85.
• Background: a clean white or very light background reads best in a crowded grid. It also makes your image easier to reuse on Shopee, Lazada and Amazon.

Additional images

Keep extra gallery images square and the same size as the main image. Mixing sizes makes the gallery jump around as shoppers swipe, which looks careless. Use these slots for different angles, close-ups of materials, a scale shot and a photo of what is in the box.

Item description images

Qoo10 listings often include long description images, built as a stack of tall graphics. These behave differently from gallery photos:

• Use a consistent width. Around 800 to 1000 pixels wide works well for both phone and desktop layouts.
• Split very tall graphics into several images rather than one huge file. Long single images load slowly on mobile data, and some upload tools will reject or shrink them.
• Keep text large. Most Qoo10 shoppers are on phones, so anything smaller than about 24 pixels tall at 1000 pixels wide becomes hard to read.

Carousell image sizes: what to upload

Carousell is more relaxed. Its help centre says you can upload up to 10 photos per listing, and photos can be any size. Carousell also stopped forcing a square crop, so portrait and landscape photos now display as shot.

Recommended settings

• Photos per listing: use all 10 if the item is worth more than a few dollars. More photos mean fewer "is it still available, can send more pics?" chats.
• Shape: square still works best for the first photo, because it shows cleanly in search results and on profile pages. Portrait (4:5) is fine for clothing and tall items.
• Size: 1080 pixels on the short side is plenty. Larger files upload more slowly and gain nothing on a phone screen.
• Format: JPG. If you shoot on an iPhone, check that your photos are exported as JPG rather than HEIC before uploading from a computer.

What Carousell buyers look for

• Real condition: show scratches, wear and any defects clearly. Hiding them leads to disputes and bad reviews.
• Everything included: one photo of the item with its box, charger, receipts or accessories laid out together.
• Proof it is yours: for higher-value items, a photo with a handwritten note showing your username and the date builds trust quickly.
• Natural light: a window with indirect daylight gives true colours and soft shadows. Avoid yellow indoor bulbs, which make colours look off.

Carousell's listing rules also ban images that are misleading or that you do not have the rights to use, so avoid lifting brand photos or another seller's pictures.

Qoo10 vs Carousell at a glance

One photo set, two platforms

The easiest workflow is to shoot once and export twice. Here is a simple approach that works for most Singapore sellers:

1. Shoot with space around the product. Leave a margin on every side so you can crop to square, portrait or landscape later without cutting anything off.
2. Keep a master copy. Save the full-size original in a folder you never upload from.
3. Export a square marketplace set. 1000 x 1000 pixels, white or light background, product filling about 80 to 85 percent of the frame. Use this for Qoo10, and it will also suit Shopee and Lazada.
4. Export a Carousell set. 1080 pixels on the short side, with the square image first, followed by condition close-ups and an "everything included" shot.
5. Name files clearly. Something like sku123-qoo10-01.jpg and sku123-carousell-01.jpg saves time when you update listings later.

Resizing dozens of images by hand for each platform is where most sellers lose time. A tool like PixelPrep lets you upload a batch once and download correctly sized versions for each marketplace, padded to square where needed instead of cropping the product.

Common mistakes Singapore sellers make

Uploading supplier photos to Qoo10 unchanged

Supplier images often come with Chinese text, watermarks or odd sizes like 750 x 1000 pixels. On Qoo10 they get letterboxed in the grid and look identical to every other seller using the same photos. At minimum, re-pad them to square and remove watermarks you do not own. Better still, shoot your own.

Using huge phone photos on Carousell

Modern phones shoot 12 to 48 megapixel images, often 3 to 8 MB each. Uploading 10 of these is slow, and Carousell will shrink them anyway. Resize first and your listing goes up faster, especially on mobile data.

Cropping too tightly

A product that touches the edge of the frame looks cramped in a thumbnail and can lose its edges if a platform crops it further. Leave a small, even margin.

Inconsistent backgrounds across a store

On Qoo10, a shop page where every product sits on a different background looks less trustworthy than one with a consistent look. Pick one background colour and stick with it.

Quick checklist before you list

• Qoo10 main image is square, around 1000 x 1000 pixels, JPG, under 1 MB
• Qoo10 gallery images match the main image size
• Qoo10 description images share one width and have readable text on a phone
• Carousell listing uses most or all of the 10 photo slots
• First Carousell photo is clean and square; later photos show condition and accessories
• No watermarks or images you do not have rights to use
• Colours checked in daylight against the real product
• Files named by SKU and platform so you can find them later

Get these basics right and your listings will look sharp on both platforms, with fewer cropped thumbnails, fewer buyer questions and fewer returns over colour or condition.
