Frequently Asked Questions
- Can I resize without losing quality?
- Downscaling (making smaller) preserves quality well. Upscaling (making larger) may reduce sharpness since new pixels must be interpolated.
- What does 'keep aspect ratio' do?
- When enabled, changing the width automatically adjusts the height proportionally (and vice versa) so the image does not get stretched or squished.
- What image formats are supported?
- You can resize JPG, PNG, WebP, GIF, and most other browser-supported image formats.
- Is there a maximum image size?
- Free users can resize images up to 10MB. Pro users can handle images up to 100MB.
