How does the image resizer work?

Upload an image, set your desired dimensions by pixels or percentage, and the tool uses the HTML Canvas API to resize it in your browser. No data is sent to any server.

What image formats are supported?

The tool supports JPEG, PNG, WebP, GIF, BMP, and most image formats that browsers can display. The resized image is downloaded as PNG for lossless quality.

Does resizing reduce image quality?

Enlarging an image beyond its original size may reduce sharpness. Reducing size generally preserves quality. The tool uses bilinear interpolation for the best results.

Is there a file size or dimension limit?

There is no hard limit. However, very large images (above 50 MP) may be slow depending on your device since all processing happens in the browser.

Can I resize images for social media?

Yes! The tool includes preset sizes for Instagram (1080x1080), Facebook (1200x630), Twitter (1600x900), and common web dimensions.
