Resize Image to 128×128
128×128 is a standard icon square — used for app and desktop icons, Discord and Tumblr avatars, custom emoji, extension icons and large favicons. This page resizes any image to exactly that, in your browser. Everything runs in your browser — nothing is uploaded. Need a smaller file instead? Compress or convert.

Why choose 128×128?
128×128 is a square image of 16,384 pixels (0.02 megapixels) in a square (1:1), mostly used for Chrome-store icons and small avatars.
1:1 square shape
The square (1:1) proportion decides how your photo is framed: plan the subject around that shape before you crop.
The exact size needed
128×128 is the exact size for Chrome-store icons and small avatars, so your image is shown as-is instead of being re-scaled or cropped by the platform.
Prints 0.43×0.43 in at 300 DPI
That is 1.1×1.1 cm at photo quality, or 0.9×0.9 in at 150 DPI for posters viewed from a distance.
About 3 KB–5 KB as JPG
A typical photo at 128×128 saves to roughly 3 KB–5 KB at good JPG quality; WebP is usually 25–35% smaller.
Sharp results
A 12 MP phone photo has 744× more pixels than 128×128, so resizing down keeps it sharp.
Framing control
Filling 128×128 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.

Getting a 128×128 icon to actually look good
At 128×128 you have 16,384 pixels to work with. Almost everything you know about resizing photos stops applying at that scale, and the difference between a crisp icon and a muddy one is decided before you resize, not after.
Crop tight first. A full photo shrunk to 128 pixels becomes an unreadable smudge. Whatever the subject is — a face, a logo, a single symbol — crop to just that with the cropper, then resize. The subject should fill most of the square.
Use PNG, not JPG. JPG compression artefacts that are invisible at full size become obvious fringing around edges at 128 pixels. PNG is lossless and supports transparency, which icons usually need. Pick PNG as the output format on this page. If the platform accepts WebP, that is smaller again at the same quality.
Start from a square or from vector art. Forcing a rectangular image into 1:1 crops the long side hard. If you have an SVG or the original logo file, export it large and square before bringing it here — scaling down from 512×512 or 1024×1024 gives a far cleaner 128×128 than scaling up from 64×64, which cannot add detail that was never there.
Check it at actual size. A 128px icon is about a centimetre wide on screen. Fine lines, thin text and subtle gradients disappear. Zoom out and look at it small before you upload it anywhere.
Need other icon sizes? PNG to ICO produces a real multi-size .ico for favicons, and JPG to ICO does the same from a photo.
Frequently asked questions
Should a 128×128 icon be a PNG or a JPG?
PNG, in almost every case. It is lossless, so edges stay sharp at small sizes, and it supports transparency, which most icon slots expect. JPG introduces visible artefacts around hard edges once the image is this small, and cannot do transparent backgrounds.
What aspect ratio is 128×128?
128×128 has a square (1:1) aspect ratio. Any size with the same ratio — for example 120×120, 144×144 — can be scaled to it without cropping.
How big will a 128×128 image print?
At 300 DPI (photo quality) 128×128 prints at 0.43×0.43 inches (1.1×1.1 cm). At 150 DPI it covers 0.85×0.85 inches, fine for posters seen from further away.
How large is a 128×128 file?
A photo at 128×128 is usually 3 KB–5 KB as a JPG, and about 2 KB–4 KB as WebP. If you need it smaller, run it through the compressor afterwards.
Will my photo lose quality at 128×128?
No — a normal phone photo is much larger, so it is scaled down and stays sharp.
Can I resize to 128×128 without cropping?
Yes. Tick “Keep aspect ratio”: the whole picture is kept, but one side may come out shorter than 128×128. Without it, the image fills 128×128 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.
