Frequently Asked Questions
Will resizing affect image quality?
Resizing can affect quality, especially when enlarging images. Our tool uses high-quality algorithms to minimize quality loss. Downscaling (making smaller) generally maintains better quality than upscaling.
What's the maximum image size I can resize?
The tool can handle images up to reasonable browser memory limits. Very large images (over 10MB) may take longer to process. We recommend resizing images that are under 15MB for best performance.
Can I resize multiple images at once?
Yes, you can process multiple images sequentially. Upload one image, resize it, download it, then proceed to the next image.
Which format should I use for web images?
WebP and AVIF offer the best compression with good quality. JPEG is widely supported and good for photos. PNG is best for images with transparency or simple graphics.
