Resize PNG
Change the width and height of PNG images while keeping transparency
Set your PNG to the exact size you need
Whether you are trimming a screenshot to fit a document, shrinking an avatar to meet an upload limit, or making a batch of product images match, resizing is one of the most common jobs a PNG needs. Doing it well means scaling cleanly and, crucially, keeping any transparency intact.
This resizer lets you type a new width and height, optionally locking the aspect ratio so the picture never distorts. It all runs in your browser, so large images resize instantly and privately without a round trip to a server.
How to resize a PNG
- Drop a PNG into the box above, or click to choose one.
- Enter the width and height you want, or lock the ratio and set just one.
- Watch the live preview update to the new dimensions.
- Click Download PNG to save the resized image.
Why resize in the browser?
Transparency stays put
Unlike tools that flatten images onto white, this keeps the alpha channel, so transparent logos and icons scale without gaining a background.
Aspect-ratio lock
Locking the ratio means you only set one dimension and the other follows, protecting you from accidentally stretching the image.
Private and instant
Nothing leaves your machine, so even confidential mock-ups resize in a moment with no waiting on an upload.
Frequently Asked Questions
Is my PNG uploaded to resize it?
No. The resizing is done by your browser on your own device, so the image is never uploaded and never stored anywhere.
Does resizing keep the transparency?
Yes. Transparent areas are scaled along with the rest of the image, so a logo or cut-out stays transparent at its new size.
Can I keep the original aspect ratio?
Yes. Lock the ratio and the height updates automatically when you change the width, so the image never looks stretched or squashed.
Can I make a PNG larger?
You can, but enlarging a raster image cannot invent detail that is not there, so upscaled pictures look softer. Shrinking always stays crisp.
Can I resize several PNGs at once?
Yes. Add multiple PNG files and download the resized versions together as a single ZIP.
