About PNG Resizer
PNG files are the format of choice for logos, icons, and graphics with see-through backgrounds, but they can get heavy fast. When a PNG is too large for an app icon slot or a web header, you need to resize it without losing that transparency.
This resizer changes a PNG to your chosen dimensions while keeping the transparent areas fully intact. It works right in your browser for free, with no sign-up and no watermark, so your graphic comes out clean. Files are processed on the spot and not held onto afterward, which keeps your work private.
Common uses
- Resizing a transparent logo to fit a website header
- Scaling app icons to exact pixel sizes
- Shrinking a PNG sticker or badge for a chat app
- Sizing a transparent graphic for a presentation slide

FAQ
Does transparency survive the resize?
Yes. The alpha channel is preserved, so transparent and semi-transparent areas stay exactly that way in the resized PNG.
Can I set an exact width and height?
Yes. Type precise pixel dimensions, and you can lock the aspect ratio to avoid stretching your graphic.
Is upscaling a small PNG a good idea?
Downscaling keeps edges crisp. Enlarging a small PNG can soften details, since the tool can only stretch existing pixels.
Will the file stay a PNG?
Yes, the output remains a PNG, keeping its lossless quality and transparency support.
Can I use PNG Resizer on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
