Why choose 350×350?

At 350×350 pixels, an image holds 0.12 megapixels in a square (1:1). It is a common choice 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

350×350 suits profile pictures and small product images. Using the exact size avoids a website scaling or cropping your image on its own.

Prints 1.17×1.17 in at 300 DPI

That is 3×3 cm at photo quality, or 2.3×2.3 in at 150 DPI for posters viewed from a distance.

💾

About 19 KB–38 KB as JPG

Expect around 19 KB–38 KB for a JPG photo at this size. Simple graphics are smaller, PNG photos several times larger.

✨

Sharp results

A 12 MP phone photo has 100× more pixels than 350×350, so resizing down keeps it sharp.

✂

Framing control

Filling 350×350 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.

Consistent 350×350 product thumbnails

Consistency sells. A grid where every thumbnail has the same size, the same background and the product at a similar scale looks professional. Mixed shapes and margins look like a flea market. Resizing to one exact square is the first step.

Set the margin before resizing. Decide how much space surrounds the product — say 10% on each side — and crop every photo the same way with the cropper. Then batch them through here in one go.

White backgrounds and JPG. Product photos on white compress well as JPG. Make sure the white is truly white (255, 255, 255) or the thumbnails will look grey against the page.

Watermark if you need to. Marketplace images get copied. A subtle mark added with the watermark tool after resizing stays legible at this size.

Speed. A 350×350 JPG is usually 15–40 KB. For a large catalogue, converting to WebP with JPG to WebP saves more.

Related squares: 300×300, 400×400 and, for zoomable product photos, 1000×1000 or larger.

Frequently asked questions

How do I make all my product thumbnails the same size?

Crop each photo to a square with the same margin around the product, then drop them all in here together — every file comes out at 350×350 and you can download them as one ZIP.

What aspect ratio is 350×350?

350×350 has a square (1:1) aspect ratio. Any size with the same ratio — for example 360×360, 320×320 — can be scaled to it without cropping.

How big will a 350×350 image print?

At 300 DPI (photo quality) 350×350 prints at 1.17×1.17 inches (3×3 cm). At 150 DPI it covers 2.33×2.33 inches, fine for posters seen from further away.

How large is a 350×350 file?

A photo at 350×350 is usually 19 KB–38 KB as a JPG, and about 13 KB–27 KB as WebP. If you need it smaller, run it through the compressor afterwards.

Will my photo lose quality at 350×350?

No — a normal phone photo is much larger, so it is scaled down and stays sharp.

Can I resize to 350×350 without cropping?

Yes. Tick “Keep aspect ratio”: the whole picture is kept, but one side may come out shorter than 350×350. Without it, the image fills 350×350 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.
