How It Works

  1. Upload your image file (PNG, JPG, WebP, AVIF, or GIF) using drag & drop or the file browser.
  2. Choose your resize method: percentage scaling or exact dimensions.
  3. Adjust the quality slider based on your needs (higher = better quality, larger file).
  4. Optionally convert to a different format (PNG, JPG, WebP, or AVIF).
  5. Click "Resize Image" and download your optimized image.

Format Comparison

PNG

Lossless compression with transparency support. Ideal for graphics, logos, and images requiring transparency. Larger file sizes.

JPG

Lossy compression, great for photographs. Universal compatibility. No transparency support. Smaller files for photos.

WebP

Modern format with 25-35% better compression than JPG. Supports transparency and animation. Excellent browser support.

AVIF

Latest format with best compression (50% smaller than JPEG). Excellent quality at low file sizes. Growing browser support.

Frequently Asked Questions

Resizing can affect quality, especially when scaling up (enlarging). Scaling down generally preserves quality well. We use high-quality resampling algorithms to minimize quality loss. Adjust the quality slider to balance file size and visual quality.

Percentage mode scales proportionally - 50% makes it half the size, 200% doubles it. Dimensions mode lets you specify exact pixel width and height. Use percentage for proportional scaling and dimensions when you need specific sizes.

For photographs: JPG or WebP. For graphics with transparency: PNG or WebP. For best compression: AVIF or WebP. For universal compatibility: JPG or PNG. WebP offers a great balance of quality, compression, and features.

The quality slider (10-100) controls the compression level. Higher values mean better quality but larger files. For JPG/WebP/AVIF, 80-90 is usually a good balance. For PNG, quality affects compression efficiency but remains lossless.
