Aspect ratio prevents accidental distortion.
A locked ratio links width and height. Fit, Crop, Pad and Percentage preserve proportions; Stretch is available only as an intentional choice and displays a warning.
Privacy
Your images stay in this browser.
Decoding, preview, resizing and ordinary export use browser APIs. Canvas re-encoding may remove embedded metadata.

Bulk Image Resizer FAQ
How do I resize an image?
Add an image, enter target dimensions, choose Fit, Crop, Pad or Stretch, then inspect the live preview before resizing.
How do I resize multiple images at once?
Add a practical batch and apply one shared resize profile. The bounded file workspace remains searchable and sortable.
How can I resize without stretching?
Keep aspect-ratio lock on or choose Fit, Crop, Pad, or Percentage. Stretch intentionally allows distortion.
What is the difference between fit and crop?
Fit keeps the complete image visible inside the target box. Crop fills the exact frame and removes overflow.
How do I keep the original aspect ratio?
Aspect-ratio lock is enabled by default. Changing width updates height and changing height updates width.
Can I resize images to exact dimensions?
Yes. Crop, Pad and Stretch create exact target dimensions. Fit creates the largest proportional image inside the box.
Can I resize for social media?
Yes. Named social presets are centrally configured. Platform recommendations can change, so confirm critical publishing requirements.
Does resizing reduce image quality?
Downscaling removes pixels and lossy formats re-encode detail. High-quality canvas smoothing and a real preview help you review the result.
Are my images uploaded to a server?
No. Ordinary resizing, preview and export run locally in your browser.
Can I resize images on mobile?
Yes. The mobile studio places the selected image and live preview before the detailed controls and uses a sticky resize action.
