Frequently Asked Questions

Is there quality loss when resizing images?

We use the Lanczos3 algorithm for high-quality resizing. Upscaling may show slight quality reduction, while downscaling has virtually no visible loss. Choose PNG output for lossless saving.

What does 'keep aspect ratio' mean?

When enabled, entering only width or height will automatically calculate the other dimension to maintain the original image's proportions. This prevents distortion.

What are the recommended image sizes for social media?

Recommended sizes: Instagram Square 1080Γ—1080, Instagram Story 1080Γ—1920, Facebook Cover 820Γ—312, YouTube Thumbnail 1280Γ—720, X Header 1500Γ—500. Use IMGLOO's presets for one-click sizing.
