HOW IT WORKS

Use the image resizer in seconds

Choose an image up to 25 MB and 25 megapixels. Enter a width or height and Orenvu calculates the matching dimension from the original aspect ratio. Unlock the ratio only when an exact shape matters, because stretching can distort the image. Output is limited to 12,000 pixels per side and 25 megapixels. Processing happens in your browser; PNG stays lossless, while JPG and WebP offer a quality control. Animated images export as one still frame.

WORKED EXAMPLE

Image Resizer: an example

A 2400 × 1600 photo resized to 1200 pixels wide with the ratio locked becomes 1200 × 800.

FREQUENTLY ASKED QUESTIONS

Image Resizer FAQ

How do I resize an image without stretching it?

Keep the aspect-ratio option selected and enter either the width or height. Orenvu calculates the other dimension from the original image.

Does resizing reduce file size?

Reducing pixel dimensions often reduces file size, but the final size also depends on the format, quality and image content. Use the Image Compressor when file size is the main goal.

Are resized images uploaded?

No. Resizing and export happen locally in your browser.

Can I enter an exact width and height?

Yes. Turn off the aspect-ratio lock and enter both values. The image will stretch if the target shape differs from the original.
