Frequently Asked Questions
How do I resize an image without losing quality?
Making an image smaller keeps it sharp. Making it much bigger can make it look soft, because the tool has to guess the new pixels. Try to start from the biggest version you have.
What is the difference between resize and compress?
Resize changes the width and height in pixels. Compress lowers the file size without changing the pixel size. You can use both together for the lightest result.
How do I keep the same shape when resizing?
Set only the width or the height and let the other one follow, so the proportions stay the same. Otherwise the picture can look stretched.
Can I resize by percentage?
Yes. For example, 50 percent makes the image half as wide and half as tall.
Are my images uploaded to a server?
No. Everything happens in your browser.
Is this tool free?
Yes, it is free with no watermark.
Pixels, Size, and Quality Explained
An image is made of tiny dots called pixels. A picture that is 1920 by 1080 has 1920 pixels across and 1080 pixels down. More pixels means more detail and a bigger file.
When you resize to a smaller size, the tool removes pixels, and the image stays clear. When you resize to a larger size, it has to invent new pixels, and the picture may lose sharpness. That is why shrinking is safe and enlarging should be done with care.
Choose the output format wisely. JPG gives small files for photos, PNG keeps full detail, and WebP is a good choice for websites.
