❓ Frequently Asked Questions
Everything you need to know about resizing images
📷 Is my image uploaded to a server? ▼
No! All processing happens locally in your browser. Your images never leave your device, ensuring complete privacy and security.
🎯 What’s the difference between JPEG, PNG, and WebP? ▼
JPEG: Best for photos, smaller file size with adjustable quality. PNG: Best for logos, graphics with transparency, lossless quality. WebP: Modern format, up to 30% smaller than JPEG with same quality.
🔒 What does “Lock Aspect Ratio” do? ▼
Lock maintains your original image proportions. When enabled, changing width automatically adjusts height (and vice versa) to prevent stretching or distortion.
⚡ What quality setting should I use? ▼
90%: Best balance – near-original quality with smaller size. 70-80%: Good for web, noticeable compression. 100%: Maximum quality but largest file size. For most uses, 85-90% is recommended.
📱 What’s the maximum file size? ▼
You can upload images up to 10MB. For larger files, the tool will prompt you to choose a smaller image.
💻 Is this tool really free? ▼
Yes! 100% free forever. No watermarks, no signup required, no hidden charges. Use it as much as you want.
🎨 Can I resize images with transparency? ▼
