Your image is smaller than the target, so the result will be upscaled and soft. Use a higher resolution photo for a sharp output.
This page outputs exactly the target size. If your image is smaller, the file is enlarged to reach it and looks softer. Enlarging cannot recover detail that was never captured.

1,024 by 1,024 is a power of two, which is why it divides cleanly into 512, 256, and 128 with no fractional pixel rounding. That makes it the natural master size for icon sets and AI reference images, and the reason smaller sizes derived from it stay sharp.
How it works
Why 1024 by 1024 keeps dividing cleanly
1,024 is two to the power of ten, so it divides evenly all the way down through 512, 256, 128, 64, and 32 with no fractional pixel left over. Graphics processors, texture pipelines, and image models prefer power of two dimensions because they map cleanly onto how memory is allocated. The practical effect for you is that a single 1,024 by 1,024 master produces a full icon set without rounding artefacts at any step.
| From | Divided by | Result | Rounding needed |
|---|---|---|---|
| 1024 × 1024 | 2 | 512 × 512 | None |
| 512 × 512 | 2 | 256 × 256 | None |
| 256 × 256 | 2 | 128 × 128 | None |
| 128 × 128 | 2 | 64 × 64 | None |
| 64 × 64 | 2 | 32 × 32 | None |
| 32 × 32 | 2 | 16 × 16 | None |
Choosing crop, pad, or stretch
A non square image has to be mapped onto a square canvas, and each method loses something different. Crop to fill scales the image until the frame is covered, then trims the overflow, so nothing is wasted but the edges are gone. Fit scales the image to sit entirely inside the frame and fills the remainder with a solid colour, so nothing is lost but bars appear. Stretch forces the exact dimensions and distorts the proportions, which almost never looks right for a photo.
- Fill crops the overflow. Best for centered subjects and general photos.
- Fit pads the remainder with a solid colour. Best when nothing may be cut off, such as a logo.
- Stretch forces the dimensions and distorts. Avoid for anything but deliberate effects.
NoteFit mode fills with a solid colour, not transparency. If you need a transparent background, export PNG and crop to a square yourself instead.
What to do when your image is smaller than 1024
A 300 by 300 photo cannot become a sharp 1,024 by 1,024 file. The tool will enlarge it so you get the exact size, and it warns you, but the result is interpolated rather than recovered. Enlarging adds pixels without adding information, so fine detail and text will look soft. Where you can, start from a larger source. If the small size is what you actually need, target that size directly instead of enlarging and then reducing.
- Exact 1,024 by 1,024 with a soft result: enlarge, which this page does by default.
- A smaller sharp square: resize down to the size you need, such as 256 by 256.
- A subject you can control: crop to a square first, then resize, so the enlargement is applied to less empty space.
Using 1024x1024 as an icon master
This is the workflow that makes the size worthwhile. Resize or draw your artwork at 1,024 by 1,024, keep it as a PNG so transparency survives, then derive the smaller sizes from that one file. Because each step divides by two, every size is a clean downscale rather than an independent resize.
- Create the master as a square PNG at 1,024 by 1,024.
- Keep generous padding, so the smaller sizes do not clip the edges of the design.
- Derive each size from the master, not from each other, to avoid compounding softness.
- To produce a multi size favicon.ico from the master, use the favicon generator.

Frequently asked questions
What is 1024x1024 used for?
It is a common master size for icon sets, AI image generator reference images, and square product or social graphics. Because 1,024 is a power of two, it divides evenly into 512, 256, 128, and 64 with no rounding.
Will my image be exactly 1024x1024?
Yes, provided the source is at least that size on both edges. If your image is smaller, the file is enlarged to reach the target and looks softer, with a warning shown. Enlarging cannot recover detail that was never captured, so start from the highest resolution you have.
Should I crop or pad a non square image?
Crop to fill when the subject is centered and edge content is expendable, which is the usual choice for photos. Pad with fit when nothing can be cut off, such as a logo or a screenshot, and match the padding colour to your background.
Can I batch resize images to 1024x1024?
Yes. Add a folder, resize every file to 1,024 by 1,024 in one pass, and download them together as a ZIP. Everything is processed on your device.
Which output format should I choose?
PNG keeps transparency and is the right choice for logos and icons. JPG gives a much smaller file for photographs. WebP and AVIF are better for the web when your audience supports them.
