About This Tool
Image Resizer lets you resize any image to exact pixel dimensions, scale by percentage, or use preset sizes for social media platforms (Instagram, Facebook, Twitter, YouTube, LinkedIn). Maintain aspect ratio with the lock feature, or set custom width and height independently. Supports JPEG, PNG, WebP, and GIF formats. All processing happens locally in your browser using the HTML5 Canvas API — your images are never uploaded to any server.
Frequently Asked Questions
Scaling down preserves quality well. Scaling up may cause slight blurriness since new pixels must be interpolated. For best results, start with the highest resolution source image.
The tool supports JPEG, PNG, WebP, and GIF. The output format matches the input format by default.
There's no hard limit since everything runs in your browser. Very large images (50MB+) may take a moment to process depending on your device.
