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.
