Square Online image size, in short: Square recommends item images of at least 2000×2000 pixels in a 1:1 (square) ratio. It accepts JPG, JPEG, PNG and GIF files up to 15 MB each, and item images are shared between your point of sale and Square Online, so one image serves both. Export square JPEGs at 2000×2000 and keep them small for fast pages.

Square Online builds your store from the Square item library, so the photos you add to items in the dashboard or on the POS appear in your online store too. Square's help article covers formats, file size and the recommended size, but questions such as how many photos an item can show and how big site banners should be are answered mostly in its community forum. This guide sets out the official numbers, flags the unofficial ones, and shows how to prepare a consistent set of product photos. The free square image maker pads any photo to 1:1 without cropping.
- Recommended: at least 2000×2000 px, 1:1 square.
- Formats: JPG, JPEG, PNG or GIF.
- Maximum file size: 15 MB per image.
- One image set for both channels: item images sync between the POS and Square Online.
- Keep files light: compress to a few hundred KB so product pages load quickly.
What size should Square Online product images be?
At least 2000×2000 pixels, square. Square's item image help article recommends that size and a 1:1 aspect ratio. A square photo shows the whole product in item tiles and product grids instead of being cropped to fit.
| Setting | Square's rule | Our recommendation |
|---|---|---|
| Size | At least 2000×2000 px recommended | 2000×2000 px exactly |
| Aspect ratio | 1:1 recommended | 1:1 for every item, so grids line up |
| File types | JPG, JPEG, PNG, GIF | JPEG for photos; PNG only for graphics |
| Maximum file size | 15 MB | Compress to about 200–500 KB |
| Same image across channels | Images sync between POS and Square Online | Choose photos that work on a POS tile and a web page |
Square's item image formats, file size limit and recommended size were checked in October 2026. Marketplaces change their rules, so confirm the current requirements in your seller dashboard before you upload a large batch.
What file types and sizes does Square accept?
JPG, JPEG, PNG and GIF files up to 15 MB. iPhone photos in HEIC format need converting to JPEG first; the free HEIC to JPG converter does that in your browser.
- JPEG: best for product photos; small files at high quality.
- PNG: for logos and graphics with flat colors or transparency; photos as PNG are much larger.
- GIF: accepted, but limited to 256 colors, so not for photos.
- 15 MB: the hard limit. Most phone photos are 2–5 MB, so they upload as they are, but compress them anyway for page speed.
Square's community team has suggested keeping images to about 500 KB or less for faster loading. The free image compressor gets a 2000×2000 JPEG well under that without visible loss. See also how to compress an image to 200 KB.
How many photos can a Square Online item have?
Square's image help article doesn't state a per-item limit for Square Online, and community moderators have given different answers over time, so check the item editor for your account. Square's bulk image upload matches one image to each item; additional photos are added to the item itself, where you can reorder them and choose the main image.
Because item images sync between the point of sale and Square Online, the main image also appears on POS item tiles. A clean product on a plain background reads well at tile size; a busy lifestyle photo doesn't.
What size should Square Online banners and section images be?
Square doesn't publish one fixed banner size, because the site editor scales and crops images to each layout. Community moderators have suggested background and header images of about 2000 px wide and at least 1000 px tall, and smaller non-background images of no more than about 1000 px on the long side.
| Image | Suggested size (community guidance) | Tip |
|---|---|---|
| Header or background image | About 2000×1000 px or larger | Keep the subject centered; edges are cropped on phones |
| Image sections and blocks | Up to about 1000 px on the long side | Match the block's shape |
| Item images | 2000×2000 px (Square's official recommendation) | Square, consistent |
| Logo | A PNG with transparency | Check it on both light and dark headers |
Preview every banner on a phone before publishing. For general website image sizes, see our website image sizes guide.
How do you make consistent Square Online product photos?
Shoot every product the same way, then export each one as a 2000×2000 square with the product filling about 80% of the frame. Consistency matters more on a small store than on a marketplace, because buyers see your whole catalogue at once.
- Shoot on the same plain background, in the same light, at the same distance.
- Convert HEIC photos to JPEG.
- Pad each photo to a square with the square image maker, or crop square if there's room.
- Resize to 2000×2000 with the resizer.
- Compress each file to a few hundred KB.
- Upload the main photo first, then extra angles in the item editor.

What are the most common Square Online image mistakes?
| Mistake | Fix |
|---|---|
| Mixed shapes in the product grid | Make every item image 1:1 |

| HEIC upload fails | Convert to JPEG first |
| Slow product pages | Compress to a few hundred KB |
| Busy lifestyle photo as the main image | Clean product photo first; lifestyle second |
| Blurry zoom | Export at 2000×2000, not smaller |

Should Square Online product photos have a white background?
Square doesn't require one, but a white or very light background is the safest choice for the main item image. It reads clearly on POS tiles and in product grids, and it keeps a catalogue of different products looking like one store.
| Background | Best for | Watch out for |
|---|---|---|
| Pure white | Most product catalogues | White products need a soft shadow to stand out |
| Light grey or off-white | White or pale products | Keep the same tone on every item |
| Brand color | Small catalogues with a strong brand | Can clash with product colors |
| Lifestyle scene | Second and third photos | Too busy for POS tiles as the main image |
Use lifestyle photos as extra images to show scale and use. For food, crafts and handmade goods, a consistent natural surface such as wood or linen can also work as the main background, as long as every item uses the same one.
