How to use Resize a PNG Image
- 1. Upload the PNG. Add the image you want resized, such as graphic.png, so the tool can read its current width and height before resampling.
- 2. Enter the target dimensions. Set Width (px) and Height (px) to the exact pixel dimensions you need, such as 800 by 600, for the resampled output.
- 3. Download the resized PNG. Save the result, such as graphic.png resampled to 800x600 pixels, once the new dimensions match the slot the image needs to fill.
When to use Resize a PNG Image
Resize a PNG Image changes the physical width and height of an image through resampling, adapting a file to whatever pixel dimensions a destination requires. Grab it whenever an existing PNG is the wrong size for where it needs to go.
- Fitting a graphic to a specific web slot. A page template expects a hero image at exactly 800 by 600 pixels, and the source graphic.png was exported at a different size entirely.
- Meeting an app icon size requirement. An app store listing requires icons at a specific pixel size, and the source artwork was designed at a different resolution that needs resampling first.
- Shrinking a large photo for faster loading. A camera photo comes in at full sensor resolution, far larger than any page display needs. Resizing it down to the actual display dimensions speeds up load times.
Examples

Input
graphic.png + 800×600
Output
graphic.png resampled to 800×600 pixels
About the Resize a PNG Image tool
Resize a PNG Image runs as plain JavaScript in your browser tab, with no server behind it. Change the physical width and height dimensions of a PNG. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's PNG Tools section, 108 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 2 settings, including Width (px) and Height (px), and the result refreshes the moment you change one. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Is Resize a PNG Image free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Are my files uploaded to a server?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
Which files does Resize a PNG Image accept?
It accepts PNG images. There is no file size cap imposed by a server; very large files are limited only by your device's memory.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I save the output?
Click the Download button once the result is ready. The file is built in your browser's memory and handed straight to your downloads folder, without passing through a server.
