FAQ

How do I resize an image online?

Upload the image, enter your desired width and height, and see the preview in real time. Confirm and export with one click.

How do I prevent distortion when resizing?

Enable "Lock aspect ratio" and only change one of the two values – the other will adjust automatically to maintain the original proportion.

Are there size presets for social media or e-commerce?

Yes. Includes presets for profile pictures, headers, posts and e-commerce products, so you don't need to remember exact dimensions.

Can I resize by percentage instead of pixels?

Absolutely. Shrink or enlarge to 50%, 200% or any percentage, ideal for quickly standardizing batches of images.

What formats can I export the resized image in?

Export in PNG (transparent), JPEG (high compression) or WEBP (modern web format). Choose the best fit for your use case.
