Making a square 600 × 600 image
How to use this tool
- Choose a JPEG, PNG, or WebP image.
- Enter dimensions and units. For physical sizes, choose the intended DPI.
- Choose the fit mode, resize, and verify the output dimensions.
Dimensions and proportions
A square 600 × 600 image works for square image slots. Cover crops the edges; contain adds a white border without stretching.
Physical size is a print setting
DPI here is used to calculate pixel dimensions. The downloaded image does not embed your chosen print DPI. Set that resolution in your printing software; the pixel count is the reliable output.
Understand the requested dimensions
A 600 × 600 canvas is square regardless of the source image’s shape. The key choice is how a landscape or portrait should fit that square. If every part of the source matters, contain it. If the square must be filled edge to edge, use cover and inspect what is cropped away.
A worked sizing example
An 800 × 600 source contained inside 600 × 600 becomes 600 × 450 with space above and below. Cover instead scales it to 800 × 600 and crops 100 pixels from each side. Stretch changes it directly to 600 × 600, which can make people or products appear unnaturally narrow.
Contain, cover, and stretch
Contain scales the whole image to fit inside the output canvas. Any remaining space is white for JPEG and can be transparent for PNG or WebP. Cover fills the canvas and crops excess at the center. Stretch fills both dimensions independently, changing proportions when the source and output ratios differ.
These choices affect composition as well as dimensions. Cover is convenient for a uniform grid, but a centered crop does not know where your subject is. For careful framing, use the crop tool first and then resize the selected composition.

Check the exported image
A square canvas does not guarantee a correct profile-photo composition. If the destination later displays the square as a circle, details near the corners can disappear. Crop around the important subject first and leave enough surrounding space for that final display shape.
Read the width and height shown in the result and inspect the image at its intended viewing size. Making the file larger in pixels is not an enhancement process: it interpolates from the available information. Keep the source if a sharper or differently framed version may be needed later.
When the resized image is still too large in KB
Pixel dimensions and file size are separate measurements. The same-sized canvas can produce very different byte counts depending on its content, format, and quality. A lossless PNG of a detailed photo can remain large after resizing, while a simple flat graphic can be compact.
If the destination imposes both dimensions and a file-size ceiling, check both after the final operation. Target-size compression may reduce the dimensions further when quality adjustment is insufficient, so verify the final download rather than assuming an earlier resize guarantees compliance.

Frequently asked questions
Is this tool free and unlimited?
Yes. It is free to use with no signup and no daily usage caps. You can process up to 20 files of up to 30MB each in one batch, then download your results.
Can I leave one dimension empty?
Yes. Enter a width or a height and leave the other blank to preserve the source proportions. If you enter both, the fit mode controls how the image fills the requested canvas.
Will enlarging a small photo restore its detail?
No. Resizing can increase the number of pixels, but it cannot recover information missing from the source. Use a higher-resolution original when the enlarged result needs close inspection.
Does resize image to 600×600 pixels also guarantee an upload will be accepted?
No. This tool changes dimensions. The destination may have additional rules for file size, format, framing, background, or document content. Check those requirements against the final result.
