About Image Resizer
Load an image, set the width or height you want, and download the resized result. Keep the aspect ratio locked so the picture is not stretched, or unlock it to set exact dimensions. The output can be saved as PNG, JPG, or WebP.
Resizing happens entirely in your browser using a canvas, so the image is never sent to a server. This is convenient for shrinking a photo before uploading it somewhere, preparing a thumbnail, or fitting an image to a required size for a form or profile.
Frequently asked questions
- Will resizing reduce the file size?
- Smaller dimensions usually mean a smaller file, and choosing JPG or WebP can reduce it further than PNG for photographic content.
- Can I make an image larger?
- Yes, but enlarging beyond the original dimensions stretches existing pixels and can look soft.
- Does it keep image transparency?
- Transparency is preserved when you export as PNG or WebP; JPG has no transparency and fills it with a background color.
