The Complete Image Size Cheat Sheet for Every Platform (2026)
Every platform wants a slightly different size, and getting it wrong crops your face off or...
Read guide2048 square is the large master size: a power of two, big enough to downscale to anything, and the maximum many platforms will store. Useful when you want one file to serve every future crop. Drop a photo in and it comes out at exactly 2048 by 2048, cropped to fit rather than squashed. Nothing is uploaded.
JPG, PNG or WEBP. Output is always 2048 × 2048.
We put the same 600 by 600 portrait through this tool at 2048 by 2048 and weighed all three outputs. JPG and WEBP at quality 90.
PNG is lossless, which is why it is 13 times heavier than JPG here and 29 times heavier than WEBP. Use PNG only when you need transparency or perfectly crisp text and lines. For a photograph at 2048 by 2048, WEBP at quality 90 came out at 110.4 KB and is almost always the right answer.
2048 by 2048 is square, and almost no camera shoots square. A photo from a phone is usually 4:3 or 3:4, and a DSLR is 3:2, so something has to give when it becomes a 2048 pixel square. Roughly a quarter of the long edge is removed to make it fit.
That is what the Fit control is for. Crop to fill scales your photo until it covers the whole frame and trims the overflow, so nothing is distorted but something is lost. Fit inside scales until the whole photo is visible and pads the gap with a colour, so nothing is lost but bars appear. Stretch forces the photo into the frame and is the only option that distorts faces.
Crop to fill is the default here because a distorted face is much more obvious than a cropped edge, and because most systems asking for a fixed size expect the frame to be filled. Switch to Fit inside when the whole image genuinely has to stay visible, such as a logo or a diagram.
Common places this exact dimension is specified.
| Use | Why this size | Format worth using |
|---|---|---|
| Archive masters | 2048 square is the large master size: a power of two, big enough to do | PNG for icons, WEBP for photos |
| High resolution print sources | 2048 square is the large master size: a power of two, big enough to do | PNG for icons, WEBP for photos |
| Texture maps | 2048 square is the large master size: a power of two, big enough to do | PNG for icons, WEBP for photos |
At this size the file gets heavy quickly. Export PNG only if you need transparency, otherwise JPG or WEBP will be far smaller.
If your original is smaller than 2048 by 2048, this tool will still produce a 2048 by 2048 file, but the extra pixels are interpolated rather than real. Enlarging interpolates, it does not add information. If you need a genuinely larger image, start from a larger original or try the image upscaler, which is honest about the same limit.
Crop to fill takes the centre of your photo. If the part that matters is off to one side, crop it deliberately first with the image crop tool, then bring the result here.
This tool fixes the dimensions, not the bytes. To land under a specific limit such as 100 KB, send the result through the image compressor, which searches for the quality that meets your target.
Drop your photo into the box above. The tool is fixed to 2048 by 2048, so the output is always exactly that, and it downloads as soon as you click. Nothing is uploaded to a server, the resize happens in your browser.
Not with the default setting. Crop to fill scales your photo until it covers the 2048 by 2048 frame and trims whatever hangs over the edge, so proportions are preserved. Only the Stretch option distorts, and it is there because a few systems genuinely want the whole image squeezed in regardless.
It depends entirely on format. Our 600 by 600 test portrait came out at 3223.5 KB as PNG, 251.5 KB as JPG at quality 90, and 110.4 KB as WEBP at quality 90. Detailed photographs will be heavier than flat graphics at the same dimensions.
WEBP if the destination accepts it, since it was 44% the size of JPG in our test at the same quality. JPG if you need maximum compatibility. PNG only for transparency or crisp text, because at this size it was 13 times heavier than JPG.
The tool will still output 2048 by 2048, but it cannot invent detail that was never captured. Upscaling interpolates between existing pixels, which softens edges. Start from the largest original you have.
No. The file is read by your browser, drawn onto a canvas and encoded there. You can confirm it by opening your network tab while you use the tool, or by disconnecting from the internet and resizing anyway.
