Frequently Asked Questions
What image sizes are supported for social media?
Our tool includes presets for all major platforms: Instagram (Square 1080×1080, Portrait 1080×1350, Story 1080×1920), Facebook (Post 1200×630, Cover 820×312), Twitter/X (1200×675), LinkedIn (1200×627), and YouTube Thumbnails (1280×720).
Will resizing affect image quality?
Resizing can affect quality, especially when enlarging images. For best results, start with high-resolution images and use the quality slider to balance file size and visual quality. Reducing size generally maintains quality well.
What's the difference between 'Contain' and 'Cover' fit modes?
Contain fits the entire image within the target dimensions, which may add letterboxing. Cover fills the entire target area, which may crop parts of the image. Use Contain for full visibility, Cover for filling specific frames.
Can I resize images without losing aspect ratio?
Yes, enable 'Maintain aspect ratio' when using custom dimensions. The tool will automatically calculate the correct height or width to preserve your image's proportions.
What's the maximum image size I can resize?
You can upload images up to 10MB. The tool supports output dimensions up to 10,000×10,000 pixels, though very large outputs may take longer to process.
