OLX is one of the largest online classifieds sites, and the quality of your listing photos has a direct impact on how many contacts you receive. Images with the wrong size show up cropped, blurry, or slow to load — which drives buyers away before they even read the description.
In this guide you'll learn the ideal photo size for OLX, the limits accepted by the platform, and how to resize any image for free, with nothing to install.
What's the ideal photo size for OLX?
OLX doesn't require an exact dimension, but it recommends and displays best images close to a square or horizontal landscape ratio. The best results come from photos between 1000 × 1000 px and 1200 × 900 px.
| Use | Recommended size | Ratio | Max size |
|---|---|---|---|
| Main listing photo | 1000 × 1000 px | 1:1 (square) | 8 MB |
| Additional photos | 1200 × 900 px | 4:3 (landscape) | 8 MB |
| Minimum accepted | 500 × 500 px | any | — |
| Maximum accepted | no fixed limit | any | 8 MB per photo |
💡 Tip: Square photos (1:1) fill the entire space in OLX's results grid, making your listing more visible and clickable. Prefer this format for the cover photo.
OLX's technical limits
Before uploading your photos, it's important to know the platform's restrictions to avoid upload errors:
- Accepted formats: JPG, JPEG, and PNG
- Maximum size per photo: 8 MB
- Maximum number of photos per listing: varies by category (usually up to 20 images)
- Recommended minimum resolution: 500 × 500 px
Photos under 500 px on any dimension are accepted, but appear at lower quality and hurt how the product is perceived. Images above 8 MB are automatically rejected on upload.
Why does photo size matter so much?
OLX displays listings in a grid of thumbnails. A poorly sized image can appear cropped on the sides or with black bars, while a well-proportioned photo fills the entire card, stands out visually, and conveys more professionalism.
Also, very large photos (over 3 MB) take longer to load on mobile — and most OLX users browse from their smartphone. A 1000 × 1000 px image in JPG with good compression comes out around 200–400 KB, loading fast without noticeable quality loss.
How to resize a photo for OLX for free
The fastest way is to use the ImageTools image resizer directly in your browser, with nothing to install and no account needed:
- Go to imagetools.com.br/en/resize-image
- Drag the photo or click to select it from your computer or phone
- Enter 1000 in the width field and 1000 in the height field (for a square format)
- Choose whether to keep the original ratio, depending on the product
- Click Resize and download the finished image
💡 Tip: If the original photo shows a product on a white background, keeping the original ratio may be better. For photos of rooms or vehicles, cropping to 1:1 works well.
Tips for photos that sell more on OLX
Resizing is the first step, but a photo's visual quality goes beyond dimensions. Here's what else makes a difference:
- Neutral background: a white or light gray background makes the product stand out and conveys professionalism. Use the background remover to clean up images with a cluttered background.
- Good lighting: photos with natural or diffused light show the product's colors and texture better.
- Multiple angles: add photos from the front, side, back, and important details.
- Avoid excessive text and watermarks: OLX may reject or downrank listings with text overlays on images.
- Proper compression: use the image compressor to reduce file size without noticeable quality loss, especially on photos over 1 MB.
Can I use photos taken with my phone?
Yes, and that's the case for most sellers. Modern phone photos have resolution that's too high for the web — a 12 MP photo comes out at around 4000 × 3000 px and can weigh 4–6 MB. For OLX, that's more than enough quality, but the file size can be a problem.
The ideal path is to resize to 1000 × 1000 px and then compress to get it under 500 KB. That combination guarantees a sharp image and a fast upload.
