Why use this private image resizer?
Your image stays on your device while the browser changes its dimensions. Locking the aspect ratio prevents accidental stretching, while exact pixel controls make the result predictable.
Image resizing tips
Reducing dimensions usually makes files smaller. Enlarging an image cannot create missing detail, so very large upscales may look soft or pixelated.
Common use cases
- Prepare exact-size profile and listing photos
- Reduce image dimensions for websites
- Scale screenshots and graphics by percentage
