Overview

Resize Image fits a selected still image within requested dimensions through the browser-local image worker path. The source header is checked before decoding and the browser creates the final download locally.

Use Cases

  • Fit a photo within upload dimension limits before submitting it to a website.
  • Create a smaller browser-local copy while preserving the original aspect ratio.
  • Combine resize and JPEG output without sending the source image to a server.

Limitations

  • This preview fits images within maximum width and height rather than stretching them.
  • The preview outputs a JPEG file by default.
  • Input bytes, dimensions, and total pixels are capped before decoding.

FAQ

Does this image resizer upload my file?

No. The selected image is read by the browser and resized through a local worker for this preview tool.

Will resizing distort the image?

No. The preview fits the image within the selected dimensions while preserving the original aspect ratio.
