Image Resizer — Resize by Pixels or Percentage, No Upload

Resize an image by exact pixel dimensions or by percentage, with an aspect-ratio lock to avoid accidental stretching, processed entirely in your browser using the Canvas API — nothing uploads to a server.

How to use Image Resizer

1. Upload your image.
2. Set target dimensions or a percentage.
3. Keep or unlock the aspect ratio.
4. Download the resized image.

Frequently asked questions

Does resizing reduce image quality?

Downscaling generally looks fine; upscaling beyond the original resolution introduces blur or artifacts since no real detail can be invented, only interpolated.

What happens if I unlock the aspect ratio?

The image stretches to fit your exact width and height independently, which can distort the image if the new ratio differs significantly from the original.

Is my image uploaded anywhere?

No. Resizing happens entirely in your browser.
