Frequently Asked Questions
What image formats can I resize?
You can resize JPG, PNG, WebP, GIF, and BMP images. The tool supports output in PNG, JPG, and WebP formats, or you can keep the original format.
Will resizing reduce image quality?
Resizing to smaller dimensions generally maintains quality. When enlarging images, some quality loss may occur since the tool creates new pixels through interpolation. For AI-powered upscaling that preserves detail, try our AI Image Upscaler.
Is there a file size or dimension limit?
Since all processing happens in your browser, there are no server-side limits. However, very large images (over 50MP) may be slower to process depending on your device.
Can I maintain the aspect ratio while resizing?
Yes! Aspect ratio lock is enabled by default. When you change the width, the height adjusts automatically to maintain proportions. Toggle the lock icon to resize to exact custom dimensions.
What social media sizes are available?
We include presets for Instagram (post, story, landscape), Twitter/X, Facebook, LinkedIn, Pinterest, TikTok, YouTube thumbnails, YouTube channel art, and common sizes like Full HD, 4K, and profile pictures.
How Browser-Based Resizing Works
This tool uses the HTML Canvas API to resize images entirely in your browser. Your images are never uploaded to any server, ensuring complete privacy. The canvas uses bilinear interpolation for smooth results when scaling down, and the output quality is set to 92% for JPG/WebP formats to maintain excellent visual quality with reasonable file sizes.
