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.
