How to Resize Images for Social Media
Every social media platform has its own recommended image dimensions. Uploading the wrong size can result in awkward cropping, blurry images, or wasted screen space. SmarterSources's Social Media Image Resizer takes the guesswork out of the process — just upload your image, pick your platform and format, and download the perfectly sized result.
Step-by-Step Guide
- Upload your image. Drag and drop any PNG, JPG, or WebP image into the tool, or click to browse your files.
- Select a platform preset. Choose from Instagram, TikTok, YouTube, Twitter/X, LinkedIn, Facebook, or Pinterest. Each platform offers multiple size options for posts, stories, profiles, banners, and more.
- Preview the result. See your resized image side-by-side with the original. Check the dimensions are exactly what you need.
- Download. Click the download button to save the resized image to your device. The filename includes the dimensions for easy reference.
Why Image Dimensions Matter on Social Media
Platforms like Instagram and Facebook automatically resize images that don't match their required dimensions. This often introduces compression artifacts, unexpected crops, or letterboxing. By uploading an image that is already the correct size, you maintain full control over how your content appears to your audience.
Privacy Guarantee
All processing happens entirely in your browser. Your images are never uploaded to any server. This makes SmarterSources the most private social media image resizer available online.
Frequently Asked Questions
What size should Instagram posts be?
Instagram supports several formats: square posts at 1080 x 1080 pixels, landscape posts at 1080 x 566, portrait posts at 1080 x 1350, and Stories/Reels at 1080 x 1920. For best results, always upload at these exact dimensions to prevent Instagram from compressing your image further.
What is the ideal YouTube thumbnail size?
YouTube recommends thumbnails at 1280 x 720 pixels with a 16:9 aspect ratio. The minimum width is 640 pixels. Use high-contrast images with readable text for the best click-through rates.
Does resizing reduce image quality?
Downscaling generally preserves quality well. When upscaling, some softness may be introduced because new pixel data is interpolated. This tool uses high-quality image smoothing to produce the best possible result. For best quality, always start with an image that is larger than or equal to your target dimensions.
What dimensions does TikTok use?
TikTok videos and cover images should be 1080 x 1920 pixels (9:16 aspect ratio). TikTok profile photos are displayed at 200 x 200 pixels. Uploading at these exact sizes ensures your content looks sharp on every device.
Can I use this tool for Twitter/X headers?
Yes. The recommended Twitter/X header size is 1500 x 500 pixels. This tool includes presets for headers, posts (1200 x 675), and profile pictures (400 x 400). Select the Twitter/X platform group and choose the format you need.
