Frequently Asked Questions
Answers to the most common questions about resizing images for social platforms.
What social media platforms are supported?
The tool supports Instagram (Post, Story, Reel), Twitter/X (Post, Header), Facebook (Post, Cover), LinkedIn (Post, Banner), YouTube (Thumbnail, Channel Art), and TikTok (Video Cover).
What is the difference between Letterbox, Cover, and Stretch modes?
Letterbox (Fit) keeps the full image visible with empty bars on the sides. Cover (Crop) fills the frame by cropping the edges. Stretch forces the image into the exact dimensions, which may distort it.
Will resizing reduce image quality?
The tool uses browser Canvas API for high-quality bicubic-style rendering. Output is downloaded as PNG at full quality. Upscaling a small image will not add detail but the pixel dimensions will be correct.
Can I enter custom dimensions?
Yes. Select 'Custom' from the presets and enter any width and height in pixels you need.
