Frequently Asked Questions
How do I resize an image without losing quality?
Our image resizer uses high-quality resampling algorithms to maintain visual quality when resizing. For best results, avoid enlarging images beyond their original size. When reducing size, our tool applies smart downscaling that preserves sharpness.
What image formats can I resize?
BGEraser supports resizing PNG, JPG/JPEG, WebP, and AVIF images. The output format will match the input format by default.
Can I resize multiple images at once?
Yes! You can upload and resize multiple images simultaneously with the same dimensions. This is perfect for batch processing thumbnails or social media images.
What is aspect ratio and why should I lock it?
Aspect ratio is the proportional relationship between an image's width and height. Locking it prevents distortion — when you change width, the height adjusts automatically to maintain proportions. This ensures your images don't look stretched or squished.
