Resize images: change width, height and resolution
Every social network, website and document asks for a different image size. Resizing lets you adjust the dimensions of photos and images without editing software, keeping the original aspect ratio so the image is not distorted.
You choose between adjusting by percentage, which is quick, or by exact width and height in pixels, when you need a specific resolution.

Frequently asked questions
Will the image be distorted?
No. The original aspect ratio is kept, so the image is not stretched.
Can I enlarge a small image?
Yes, but enlarging beyond the original size reduces sharpness, because the software has to invent pixels that do not exist.
What is the advantage of using a percentage?
It is faster and works when you just want a smaller or larger version, without a specific measurement.
What are the limits of the free plan?
The free plan allows 10 conversions per day, with files up to 60 MB and no sign-up required. The Premium plan removes the daily limit and the ads.
