How to use Social Media Image Resizer
- Choose the image and select the destination platform preset.
- Preview how the photo is contained within the target canvas.
- Pick a closer-matching preset or crop first if blank margins appear.
- Download the resized PNG ready for upload.
Practical example
Place a landscape photo inside a 1080 × 1350 portrait post while preserving the full photo.
When to use Social Media Image Resizer
- Prepare a landscape photo for a portrait-format story post
- Resize a graphic to a platform's recommended profile header size
- Create a link-preview-sized image for a shared post
Important limitations
- The image is contained on a light background rather than automatically cropped to fill every edge.
- Platform safe zones and current recommendations can change, so preview important text in the destination app.
Troubleshooting Social Media Image Resizer
The result has blank margins
Choose a preset closer to the source aspect ratio or crop the image first when edge-to-edge coverage is required.
