Frequently Asked Questions
- Does resizing blur images?
- Downscaling doesn't blur. Upscaling causes some blur or pixelation from interpolation algorithms — the larger the upscale, the more noticeable. Suggest max 2× upscale.
- How to avoid distortion?
- Check 'maintain aspect ratio'. Set only width or height, the other auto-calculates proportionally, preventing stretch distortion.
- How to batch resize?
- Upload multiple images, set uniform parameters (e.g., all to width 800px), tool batch processes and zips downloads.
