How to Resize an Image for Social Media: Sizes and Steps

Infinall AI has a Resize tool in the image editor of Studio. Crop and Fit are free on every plan and use no credits.

1. Upload your picture to the canvas or make one, then select it and choose Edit.
2. In the toolbar named Image editing tools, choose Resize (shortcut R).
3. In Resize mode, choose Crop or Fit.
4. Type the size in the W and H boxes, for example 1200 and 628 for a wide LinkedIn image.
5. Choose Apply. The resized picture appears as a new image next to the old one, so the original is kept.
6. Open the Image actions menu on the new picture and choose Download. Downloading never uses credits.

Crop keeps the busiest part of the picture, such as a logo or a headline, and not always the centre. Fit keeps the whole picture and leaves the spare area see-through, so the result is a PNG with empty edges. Crop and Fit accept a width and height from 64 to 4096 pixels, and each picture you upload can be up to 10 MB.

Turning a wide photo into a tall story with Crop throws away most of the picture. AI Extend, inside the same Resize panel, adds new picture around the edges instead. Under Target aspect you choose 1:1, 16:9, 9:16 or 4:5, can type what should fill the new area, and then choose the Extend to button. Your original picture stays as it is in the middle. AI Extend uses credits and shows the price before you confirm, and nothing is charged if the edit fails.

If you are making a new image rather than resizing an old one, choose the shape before you make it. Image settings has nine aspect ratios, including 1:1, 4:5, 9:16, 16:9, 2:3 and 1.91:1, and Auto picks a shape from the words in your prompt, such as Instagram story. There is no custom size for a new image, so make it in the closest shape and then use Resize for the exact pixels.

• Stretching the picture by changing only one side. Faces and logos look wrong right away.
• Letting the app crop for you. Apps fit pictures to their own shapes, and a crop may hit your product.
• Making one size and using it everywhere. A square that works in a feed leaves bars or gets cut in a story.
• Putting text near the edges of a story or Pin, where buttons and captions cover it.
• Enlarging a small picture with a plain resize. Upscale it first, then crop or fit.
• Uploading a huge file. It can fail, or the platform compresses it hard. Stay under the limit in the table.

For one picture and one platform, a free online resizer is the fastest choice, and Infinall has free resizers for Instagram posts, Pinterest Pins, Facebook ad images and more. Use the Studio when you want to keep your brand, make new images or turn one picture into many sizes in one place. Resize with Crop or Fit and the Grade colour presets are free on both plans. The Free plan gives 1,000 credits every month with no card, which you spend on AI work such as AI Extend or making new images. Pro costs $10 for the first month, then $30 a month or $299 a year, and gives 3,000 credits a month. Once your sizes are ready, you can plan and publish the posts from the Social Hub calendar.
