Frequently Asked Questions

Common questions about Resize Image and client-side processing.

Can I resize multiple images at once?

Yes. You can drop multiple images simultaneously. With aspect ratio lock enabled, the entered dimension scales each image proportionally relative to its original size.

What is the difference between resizing and compressing?

Resizing changes the physical pixel dimensions (e.g. 4000×3000 to 2000×1500), whereas compressing reduces file byte size by optimizing image data and encoding without altering pixel dimensions.

Can I resize an image without changing its format?

Yes. FILEMORPH preserves the original file format (PNG remains PNG with full transparency, JPG remains JPG, and WebP remains WebP).

What happens if I unlock the aspect ratio?

When aspect ratio lock is disabled, width and height can be configured independently. This allows custom dimensions but may stretch or distort the image.

Are my images uploaded to any server?

No. Resizing executes 100% locally in your browser memory using client-side Canvas APIs. Your files never leave your device.
