About this tool
Websites, marketplaces and social platforms each expect specific image sizes. Resize by exact width and height or by percentage; the aspect-ratio lock prevents stretched images. Downscaling uses high-quality browser smoothing.
Frequently asked questions
Can I enlarge images?
Yes, but enlarging cannot add detail, so upscaled images may look soft.
What does the aspect ratio lock do?
When it is on, entering only a width (or height) calculates the other side automatically so the image keeps its proportions.
Does resizing change the format?
Only if you pick a different output format. By default the original format is kept.
Is Image Resizer private?
Yes. This tool processes files entirely in your browser, so your files are not uploaded to our servers.
