Frequently Asked Questions

How do I resize an image without losing quality?

Making images smaller (downscaling) typically preserves quality. For best results, start with a high-resolution image. Our tool uses advanced algorithms like Lanczos resampling to maintain sharpness. If you need to enlarge images, we recommend using our AI-powered upscaling feature.

What's the difference between resizing and resampling?

Resizing changes the pixel dimensions (width × height). Resampling changes the pixel density (DPI/PPI). Our tool handles both - you can set exact dimensions and adjust DPI for printing.

What are the best dimensions for Instagram?

Instagram recommends: Square posts (1080x1080), Portrait (1080x1350), Landscape (1080x566), Stories (1080x1920). All images will be displayed at up to 1080px width.

Can I resize multiple images at once?

Yes! Our batch resize feature allows you to select multiple images and resize them all to the same dimensions. Perfect for bulk editing product photos or preparing multiple images for a website.

Do you maintain transparency when resizing PNG?

Absolutely! PNG transparency is preserved during resizing. WebP transparency is also supported. Your images with transparent backgrounds will remain transparent.

What's the maximum image size?

You can upload images up to 50MB. Maximum output dimensions are 8000x8000 pixels. For larger requirements, you may need to reduce quality first using our compressor tool.

Can I resize images for printing?

Yes! You can set dimensions in inches or centimeters with DPI settings. Standard print resolutions: 300 DPI for high-quality prints, 150 DPI for posters, 72 DPI for web use.
