How to Resize an Image for Social Media in 3 Easy Steps
Follow these three simple steps to prepare an image for a social media placement. No software installation required. Free and secure.
Choose an Image
Select one JPG, JPEG, PNG, WebP, AVIF, or BMP image from your device, or drag and drop it into the browser.
Select a Platform and Preset
Choose Facebook, Instagram, LinkedIn, X, or YouTube, select the required placement, then use Crop to Fill or Fit Entire Image and adjust the framing.
Preview and Download
Review the exact output dimensions and visible composition, choose JPG or PNG, then download the resized image.
How Does the Social Media Image Resizer Work?
The CompressFly social media image resizer converts one source image into the exact pixel dimensions of the selected Facebook, Instagram, LinkedIn, X, or YouTube preset. Crop to Fill scales the image until the target canvas is covered and lets you reposition or zoom the crop. Fit Entire Image keeps the whole source visible and fills unused space with your selected background color.
Profile presets include a circular display guide, while selected Story, cover, and header presets show suggested safe areas for important content. These guides help with composition but are not part of the downloaded file. The finished image is exported as JPG or PNG directly in your browser.
What "in your browser" means
- No image file is uploaded to a server
- Resizing, cropping, and export are processed locally on your device
- The finished JPG or PNG image is downloaded directly from your browser

Social Media Image Resizer FAQ
How do I resize an image for social media?
Resize an image in three steps: 1. Add one supported image. 2. Choose a platform and placement preset, then adjust the crop or fit. 3. Select JPG or PNG and download the image at the preset dimensions.
Which social media platforms are supported?
The preset selector includes Facebook, Instagram, LinkedIn, X (Twitter), and YouTube. Each platform includes sizes for the placements implemented in the tool.
Does the tool create the exact preset dimensions?
Yes. The exported JPG or PNG uses the exact width and height shown for the selected preset.
What is the difference between Crop to Fill and Fit Entire Image?
Crop to Fill covers the full target canvas and can remove content outside its edges. Fit Entire Image keeps the complete source visible and adds the selected background color where the proportions do not match.
Are the safe-area and circular guides included in the download?
No. They appear only in the editor to help you position important content. The exported image does not contain the guides.
Are my images uploaded to a server?
No. Resizing and export run locally in your browser, so the image is not uploaded to a server.
