Resize Image to 600 × 600 Pixels
A square 600×600 output, ready in two taps. The image is scaled to cover the square and centre-cropped so nothing is stretched, or you can switch to fit mode and pad instead.

How to make an image 600×600
- Select your photo.
- The target is preset to 600 × 600 — press Resize.
- Download the square result.
Switch between Fill (crop to square, default) and Fit (letterbox with a chosen background) in the options.
Where 600×600 is used
- Marketplace product photos. Several e-commerce platforms specify 600×600 as the minimum square listing image.
- Print-on-demand mock-ups and catalogue grids.
- Forum and community avatars at the higher end of the size range.
- Email newsletter product tiles, where a consistent square keeps the grid tidy.
Getting the crop right
A centre crop is the right guess most of the time, but not always — if your subject sits off to one side, crop the image to a square first with the square crop tool, choosing exactly what to keep, then resize the square to 600×600. Two steps, much better framing.
Resampling quality
Downscaling is where cheap tools give themselves away. Throwing an 8000 px image
into a single drawImage call at 800 px makes the browser sample roughly
one pixel in a hundred, which produces aliasing on fine detail — moiré on fabric,
jagged edges on text, sparkle on foliage.
This tool steps the image down in halves and finishes with a high-quality Lanczos pass, so every source pixel contributes to the result. Aspect ratio, transparency and EXIF orientation are preserved throughout.
Frequently asked questions
Are my images uploaded to your server?
No. The image is decoded, processed and re-encoded by your own browser using the Canvas and Web Worker APIs. There is no upload endpoint for this tool — open your browser's network panel while you use it and you will see no request carrying image data.
My photo is not square — what gets cut off?
In Fill mode the longer dimension is trimmed equally from both edges, keeping the centre. In Fit mode nothing is cut; the image is scaled to fit and the remaining space is filled with the background colour you choose.
Is 600×600 enough for printing?
At 300 DPI that is a 2×2 inch print, which is exactly the standard US passport photo size. For anything larger you want more pixels.
What happens to my file when I close the tab?
It is gone. The image only ever exists in your browser's memory as an object URL; closing or refreshing the page discards it. Nothing is written to our servers, and nothing is stored on your device unless you download the result.
