Follow the steps below with the free Resize Image tool — it runs entirely in your browser, needs no upload, account or watermark, and finishes in about a minute.
Step by step
Centre-crop the source to 1:1 so the subject is balanced; this guarantees 500×500 will not look stretched.
In the resizer type width 500 and height 500 with the ratio locked.
Downscaling from a large file stays crisp; upscaling a tiny image past about 2× turns soft.
PNG for logos/icons, JPEG for photos.
Pro tips & common mistakes
- If the source is a landscape, crop square before resizing to avoid awkward stretched faces.
- For a crisp icon, work from the largest square you have and downscale to 500.
- Batch up to 30 listings to one uniform 500×500 set and download a ZIP.
