Frequently Asked Questions

Everything you need to know about image resizing

What does scale image by percentage mean?

Scaling an image by percentage resizes it relative to its original dimensions. For example, 50% makes the image half the size, 200% doubles it, and 100% keeps it unchanged.

What percentage range can I use?

You can scale images from 1% (very small) up to 500% (5× the original size). The aspect ratio is always preserved.

Does scaling affect image quality?

Reducing the size (below 100%) generally maintains quality. Enlarging (above 100%) may reduce sharpness as the image is upscaled. For best results when enlarging, start with a high-resolution original.

Is scaling the same as resizing?

Scaling is a type of resizing that works proportionally by percentage, preserving the aspect ratio. Regular resizing lets you set exact pixel or unit dimensions.

Are my images uploaded to a server?

No. All processing happens entirely in your browser. Your images never leave your device and are never uploaded to any server.

Can I scale multiple images at once?

Yes. You can upload multiple images and they will all be scaled to the same percentage. Download them individually or as a zip file.
