FAQ

Q1: Can I resize multiple images at once?

Yes! Select or drag multiple images (up to 20), resize them all with one click, and download as a ZIP file.

Q2: How do I keep aspect ratio when resizing?

Aspect ratio is locked by default. When locked, changing width automatically adjusts height (and vice versa) to maintain original proportions. Uncheck to resize freely.

Q3: What are the ecommerce presets?

Click preset buttons like 'Amazon 1000×1000' or 'Shopee 800×800' to set exact platform dimensions. The preset name shows near the preview.

Q4: Will resizing affect image quality?

Enlarging images may reduce quality as pixels are interpolated. Shrinking images generally preserves quality well. For best results, start with high-resolution original images.

Q5: Are my images uploaded anywhere?

No. All resizing happens locally in your browser using JavaScript. Your images never leave your device, ensuring complete privacy.
