Why 320×320?
320×320 is a popular size for small square avatars and thumbnails. Uploading the exact size avoids blurry automatic scaling and unexpected cropping by the website.
Choosing a fit mode: "Crop to fill" keeps the frame full and trims the edges, which is best for photos. "Fit inside" keeps everything visible, which is best for logos and screenshots. "Stretch" forces the shape and can distort faces, so use it only when you must.
Quality note: shrinking a picture keeps it sharp, but enlarging a small picture cannot add detail, so very small originals will look soft at large sizes.
Size facts for 320×320: the ratio is 1:1 (square), the image has about 0.10 megapixels, and printed at 300 dpi it measures roughly 1.1 × 1.1 inches.
A typical 12 megapixel phone photo has about 117 times more pixels than 320×320, so resizing down is safe and keeps the picture sharp. Photos smaller than 320×320 will look soft if enlarged.
Best workflow: first crop or choose the fit mode, then resize to 320×320, and only compress afterwards if a file size limit applies. Doing it in this order keeps the quality highest. Your photo never leaves your browser.
Questions
How do I resize an image to 320×320 pixels?
Choose your picture, check that the size boxes show 320 and 320, and press the picture button. Then download the resized file.
What happens if my photo is not the same shape?
Pick a fit mode. "Crop to fill" cuts the extra edges, "Fit inside" keeps the whole picture and adds white bars, and "Stretch" changes the shape of the picture.
Is my image uploaded?
No. Resizing happens in your browser and nothing is sent to a server.
Can I use other dimensions?
Yes. Type any width and height in the boxes, up to 8000 pixels.
What is the aspect ratio of 320×320?
320×320 is 1:1, a square shape. If your photo has a different ratio, "Crop to fill" trims the edges and "Fit inside" adds bars so nothing is cut.
How big will the 320×320 file be?
A typical JPG at 320×320 is roughly 12 to 50 KB depending on detail. If a site needs a smaller file, resize here first and then use the <a href="/compress-image/">compress tool</a>.
