About this tool
Resizing changes an image’s pixel dimensions — useful for fitting a website layout, meeting an upload’s maximum dimensions, or shrinking a huge photo before sharing. Setting the width keeps the aspect ratio so nothing looks stretched.
This tool preserves the source format, so a transparent PNG stays a transparent PNG. All processing is local to your browser.
Questions
Does resizing keep the aspect ratio?
Yes. You set the width and the height adjusts automatically so the image isn’t distorted.
Can I make an image larger?
You can, but enlarging past the original size will look softer since there’s no extra detail to add.
Will it change my file format?
No — the output keeps the original format by default.
