Why Use This Resizer

Exact Dimensions or Percentage Scale

Enter a precise width and height in pixels or scale your image by a percentage. Need it at exactly 1200 by 630 pixels for a blog thumbnail? Done in seconds.

Aspect Ratio Lock

Toggle aspect ratio lock and the tool automatically calculates the correct height when you change the width, and vice versa. No more stretched or squashed images.

Social Media Presets

One-click presets for the most common sizes. Instagram Square at 1080x1080, Twitter Header at 1500x500, Facebook Cover at 820x312, HD at 1280x720 and 4K at 3840x2160. Always up to date with current platform requirements.

Bulk Resize

Drop multiple images into the workspace, select them all, set your target dimensions and resize the whole batch in one operation. Download everything as a ZIP file when done.

Common Questions

Can I resize images without losing quality?+

Reducing an image slightly from its original size keeps quality sharp. The tool uses bicubic resampling by default which produces clean edges. Avoid enlarging images significantly as that will introduce some softness regardless of the method used.

What is the best size for Instagram posts?+

Instagram Square is 1080x1080 pixels. For portrait posts use 1080x1350. For stories and reels use 1080x1920. Use the preset buttons for the most common sizes.

Can I resize a PNG without losing transparency?+

Yes. Resizing a PNG keeps the transparent background intact as long as you export it as PNG.

How do I resize multiple images to the same size?+

Drop all your images into the workspace, select them in the file list, set your target dimensions and click apply. The bulk operation resizes every selected file to the same size.

What happens if I enter a width without a height?+

Enable aspect ratio lock and the tool calculates the correct height automatically based on your image's original proportions.

Is there a file size or image count limit?+

No server-side limits. Very large images depend on your device's available memory. Most modern devices handle images up to 50 megapixels without issue.
