Step 1: Resize to the Right Dimensions
Open the Image Resizer and load your image. Enter the exact width and height from the table above for your target platform. If your source image has a different aspect ratio, you may need to crop before resizing to avoid stretching. For example, turning a landscape photo into an Instagram Story (9:16) requires cropping to portrait orientation first, then resizing to 1080×1920.

Social platforms re-compress your images on upload, and heavy re-compression degrades quality. By uploading an already-optimized image, you give the platform’s algorithm less work to do, resulting in a sharper final image. Run your resized image through the Image Compressor at 85% quality. This is the sweet spot for social media: high enough quality that the platform’s re-compression does not compound visible artifacts, low enough that uploads are fast.

Selling products on social media? Clean backgrounds dramatically increase engagement. Use the Background Remover to isolate your product, then place it on a solid color that matches your brand. White backgrounds are clean and professional; bold colored backgrounds grab attention in a feed. This is especially effective for Instagram carousel posts showcasing multiple products.

- Save your sized templates. Once you resize an image for Instagram Feed, save it as a template so you know the exact dimensions next time.
- Create multiple sizes at once. When you design a graphic, resize it for all platforms you use in one session. Same content, different crops and sizes.
- Use portrait orientation on feed platforms. Portrait (4:5) images take up more screen real estate than landscape, increasing engagement.
- Keep text in the safe zone. Most platforms crop images slightly in preview. Keep important text and faces away from edges.
