Frequently Asked Questions

Does resizing reduce image quality?

Significantly enlarging an image can reduce quality as it stretches existing pixels. Our tool uses smart interpolation to maintain the best possible quality. Reducing an image's size typically retains excellent clarity.

What does "maintain aspect ratio" mean?

The aspect ratio is the proportional relationship between an image's width and height. Keeping this ratio locked ensures your photo doesn't look distorted. When enabled, changing the width automatically adjusts the height proportionally.

What image formats can I resize?

You can resize all common formats including JPG, PNG, WEBP, GIF, and BMP. The tool preserves the original format unless you choose to convert it during the process.

Is there a file size limit?

Yes, to ensure fast performance for all users, there is a maximum file size limit, which is clearly stated on the tool page. Most standard photos from smartphones and cameras are well within this limit.

Can I use the Image Resizer on my phone?

Absolutely. The tool's interface is fully responsive and works seamlessly on smartphones and tablets. You can resize images directly from your mobile device's gallery.
