Transparent images stay transparent in PNG/WebP. JPG does not support transparency, so transparent areas become white. Enlarging an image cannot restore missing detail.

Frequently asked questions
Is this image resizer free?
Yes. You can resize and download supported images without creating an account.
Are images uploaded to ZM Softwares?
No. This tool processes image data in your browser; the image is not sent to our server.
Will resizing reduce image quality?
Reducing dimensions removes pixels. Increasing dimensions cannot recover lost detail. JPG and WebP quality settings also affect the output size and appearance.
Convert image formats after resizing
Need a different file type? Our browser-based converters work with the same JPG, PNG and WebP formats.
