Image Resizer

Resize images by reducing dimensions proportionally (maintaining aspect ratio). Avoid enlarging beyond original size as it causes pixelation. Use PNG for graphics with text/logos, JPG at 80–90% quality for photos. This tool processes images locally in your browser — no upload needed.

Web images: Full width banner 1920×1080px, Blog post 1200×630px, Profile photo 400×400px, Thumbnail 300×200px. Keep file size under 200KB for fast loading. Use WebP format for best compression with quality.

India passport photo: 35×45mm (approximately 413×531px at 300 DPI). For digital submission: 200×200px minimum. Visa photos vary by country. Use our Aadhaar photo resizer for government document sizes.

Downscaling (making smaller) generally preserves quality well. Upscaling (making larger) causes pixelation/blur because you're adding pixels that weren't there. This tool uses high-quality Lanczos interpolation via canvas API for the best possible output.

This tool supports JPG/JPEG, PNG, WebP, GIF, BMP and most browser-supported image formats. Output can be saved as JPG or PNG. For transparent images (logos, icons), always use PNG output to preserve transparency.
