Can I preserve the original format and aspect ratio?
Yes. The source format is selected by default. With ratio lock enabled, changing either dimension recalculates the other from the original width-to-height ratio.

Image Resizer
Resize JPEG, PNG, or WebP locally in px, mm, cm, or in with explicit DPI conversion. Lock the aspect ratio and verify exact output pixels before download.
Three simple steps
How to use Image Resizer
- 01
Choose a valid still JPEG, PNG, or WebP within the local safety limits.
- 02
Choose px, mm, cm, or in; physical units use the selected DPI, and ratio lock recalculates the other dimension.
- 03
Check the actual pixel output, choose encoding settings, resize, and download.
