Format guide
About resize images online
Resizing changes an image's pixel dimensions. A smaller width and height can dramatically reduce storage and loading time, while an exact target size helps images fit websites, forms, profile fields and presentation layouts.
Enter a width, a height or both. Keep aspect ratio is enabled by default to prevent stretching; the image is fitted within the requested bounds. The result keeps the source format when supported and is rebuilt without private descriptive metadata.
When should I use it?
- Reduce a large phone photo to a practical 1920-pixel web image.
- Fit a picture inside a profile, listing or document size requirement.
- Create a lighter preview copy while preserving the original full-resolution file.

Frequently asked questions
What does keep aspect ratio do?
It preserves the relationship between width and height so people and objects do not look stretched.
Can I make an image larger?
Yes, but enlarging creates new pixels by interpolation and cannot reveal detail missing from the source.
Will transparency be preserved?
Transparency is retained for PNG and WebP output. Formats without alpha support cannot store it.
