Will resizing reduce image quality?

Downscaling generally preserves quality well. Upscaling can cause blurriness since new pixels are interpolated.

Can I resize to exact pixel dimensions?

Yes. Enter exact width and height, or turn on "Keep aspect ratio" and set just one dimension.

Can I resize multiple images at once?

Yes. Use the Batch tab to add several images and resize them all to the same dimensions; download individually or as a ZIP.

What formats are supported?

The resized image is output as PNG. For other formats, use our Convert Image tool after resizing.

Instagram: 1080×1080 (square), 1080×1350 (portrait). Twitter/X: 1200×675 (landscape). Use "Keep aspect ratio" and set the longest side to match.
