Resize Image to 300×300
300×300 is the workhorse square of the web: company logos on business directories, seller photos on marketplaces, course thumbnails, podcast episode art and a hundred upload forms that just say \u201c300 by 300\u201d. Everything runs in your browser — nothing is uploaded. Need a smaller file instead? Compress or convert.

Why choose 300×300?
300×300 is a square image of 90,000 pixels (0.09 megapixels) in a square (1:1), mostly used for profile pictures and small product images.
1:1 square shape
The square (1:1) proportion decides how your photo is framed: plan the subject around that shape before you crop.
Where it is used
300×300 suits profile pictures and small product images. Using the exact size avoids a website scaling or cropping your image on its own.
Prints 1×1 in at 300 DPI
That is 2.5×2.5 cm at photo quality, or 2×2 in at 150 DPI for posters viewed from a distance.
About 14 KB–28 KB as JPG
A typical photo at 300×300 saves to roughly 14 KB–28 KB at good JPG quality; WebP is usually 25–35% smaller.
Sharp results
A 12 MP phone photo has 135× more pixels than 300×300, so resizing down keeps it sharp.
Framing control
Filling 300×300 from a 4:3 phone photo trims about 25% of it. Drag the preview to choose what stays, or tick “Keep aspect ratio” to keep it all.

What 300×300 is good for
300 pixels is the sweet spot where a square is still small enough to load instantly but large enough to stay sharp when a phone renders it at 2× density in a 150-pixel slot. That is why so many listing and directory platforms converged on it.
It is also the size most often requested for a logo. If that is what you are making, two things matter more than the resize itself: export from the original vector or the largest raster you have, and choose PNG so the edges stay crisp and the background can be transparent. A logo saved as JPG at 300×300 will have visible grey fringing around the lettering.
For photographs, JPG is the better pick and will typically land between 20KB and 60KB. Crop to the subject first — at 300 pixels a wide shot reduces everyone in it to a few pixels of face.
Worth knowing: 300×300 pixels is not the same thing as 300 DPI. DPI only means something when you print. If you were sent here looking for a one-inch print, see 1×1 inch, which is the same pixel count described in print terms. For a larger web square, use 600×600.
Frequently asked questions
Is 300×300 pixels the same as 300 DPI?
No. 300×300 is a pixel count; 300 DPI is a printing density. A 300×300 pixel image printed at 300 DPI comes out exactly one inch square. DPI has no effect at all on how an image looks on a screen — only the pixel dimensions matter there.
What aspect ratio is 300×300?
300×300 has a square (1:1) aspect ratio. Any size with the same ratio — for example 320×320, 350×350 — can be scaled to it without cropping.
How big will a 300×300 image print?
At 300 DPI (photo quality) 300×300 prints at 1×1 inches (2.5×2.5 cm). At 150 DPI it covers 2×2 inches, fine for posters seen from further away.
How large is a 300×300 file?
A photo at 300×300 is usually 14 KB–28 KB as a JPG, and about 10 KB–20 KB as WebP. If you need it smaller, run it through the compressor afterwards.
Will my photo lose quality at 300×300?
No — a normal phone photo is much larger, so it is scaled down and stays sharp.
Can I resize to 300×300 without cropping?
Yes. Tick “Keep aspect ratio”: the whole picture is kept, but one side may come out shorter than 300×300. Without it, the image fills 300×300 exactly and the edges that do not fit the 1:1 shape are trimmed.
Are my images uploaded?
No. Resizing happens entirely in your browser. Nothing is transmitted or stored, and you can disconnect from the internet after the page loads and it still works.
