Will resizing reduce image quality?

Our high-quality resizing algorithm maintains maximum quality. Upscaling (making images larger) may reduce quality, but downscaling (making smaller) preserves quality well.

What's the best Instagram image size?

For Instagram posts, use 1080×1080 px (square), 1080×1350 px (portrait), or 1080×1920 px (portrait/story). For Stories and Reels, use 1080×1920 px.

Can I resize multiple images at once?

Currently, you can resize one image at a time. This ensures maximum quality and processing speed for each image.

Is the image resizer free?

Yes! ImageNerd's image resizer is completely free with no limitations, watermarks, or registration required.

What if I don't know the exact dimensions I need?

Use our social media presets for popular platforms, or experiment with custom dimensions. Our preview feature lets you see the result before downloading.
