How to Use

Resize images for social media with this straightforward process:

1. Identify your target platform and format. Determine where the image will be posted (e.g., Instagram feed, Facebook cover, YouTube thumbnail) and look up the exact dimensions using the included size chart.
2. Choose a resizing tool. For one-off resizes, any tool with presets works well. For batch resizing, choose a tool that supports multiple files. For precise control, select a tool with manual dimension input.
3. Upload your image. Drag and drop or browse to upload. Most tools accept JPEG, PNG, and WebP formats.
4. Select the preset or enter dimensions. If the tool has social media presets, select the appropriate one. Otherwise, enter the exact width and height manually. Pay attention to whether the platform requires landscape, portrait, or square orientation.
5. Adjust the crop area. Position the crop frame to keep the most important content in the visible area. Be aware that some platforms crop images further in certain views (like Instagram feed crops square from landscape).
6. Download and verify. Download the resized image and verify the dimensions match the platform requirements. Check that the image is sharp and no important content was cropped out.
