Image Resizer FAQ
Will resizing reduce image quality?
Making an image smaller keeps it sharp. Making it larger than the original can look soft, because no new detail can be added.
Can I resize by percentage instead of pixels?
Yes. Choose the percentage option and enter a value such as 50% to halve both the width and the height.
Is Image Resizer free to use?
Yes. Image Resizer is completely free. There is no signup or account, and PenguPix does not add its own watermark to your files.
Are my files uploaded anywhere?
No. Image Resizer runs in your browser, so your files stay on your device and are never uploaded to a server.
Does Image Resizer work on my phone?
Yes. It works in modern mobile and desktop browsers such as Chrome, Safari, Edge and Firefox.
