Resize an image to 64 × 64 pixels for tiny icons, sprites, and skins
Sixty-four pixels square is tiny, only about four thousand pixels in total, yet it is a standard size for favicons, game sprites, small icons, and thumbnail avatars. This free online tool resizes any picture to exactly 64 × 64 in your browser, with nothing uploaded and nothing to install.
This page explains when 64 × 64 makes sense, how to design pictures that survive such a small size, why PNG usually works best, and how to turn a non-square image into a clean square. The 64 × 64 target is already filled in for you.
When 64 × 64 makes sense
- Favicons and site icons. Browser tabs and bookmark lists show tiny versions of a site's icon, and 64 × 64 is one of the sizes commonly prepared for that.
- Game sprites and skins. Pixel-art games and character skins often use a 64 × 64 grid. Minecraft skins, for example, are 64 × 64 images.
- Small icons in interfaces. Toolbars, lists, and dashboards use compact icons that load instantly.
- Thumbnail avatars. Comment threads and member lists show users at very small sizes.
Check the destination's requirements, since some formats are strict about file type, transparency, and layout.
Resizer, converter, or both
Making a 64 × 64 file is a resize of the picture's pixel dimensions, and picking a different output format at the same time is a conversion. The tool does both in one step in your browser, so it works like a lightweight online app, with no installation.
Designing for tiny sizes
At 64 × 64 every pixel counts. A few habits make a big difference.
- Pick one clear subject. Busy scenes collapse into noise.
- Use thick shapes and strong contrast. Thin lines and small text disappear.
- Crop tightly before resizing so the subject fills the square.
- Use Crop mode for faces and objects, and Fit mode for logos that must stay whole.
- Check the Resized preview at actual size, since a tiny image is judged at a glance.
Step by step: making a 64 × 64 image
- Add your image by dropping it on the upload area or browsing for it. JPG, PNG, WebP, HEIC, and GIF files up to 50 MB work, including photos straight from a phone.
- Check the Width and Height boxes. They start at 64 and 64, and you can still edit them if you need something slightly different.
- Pick a Resize mode. Crop fills the square for photos and subjects, and Fit keeps a logo whole with a white or black background.
- Choose an Output format. PNG keeps tiny images crisp and supports transparency. JPG is fine for a small photographic avatar.
- Click Resize Image, compare the Original and Resized previews and their details, then click Download Image.
Everything runs in your browser, so the picture is never uploaded.
PNG keeps tiny icons crisp
At this size, file size is almost never a problem, since a 64 × 64 PNG is typically only a few kilobytes. PNG keeps flat colors and sharp edges exactly and can hold transparency, which is why it is usually the best choice for icons and sprites. JPG's compression smudges hard edges, which is more noticeable on tiny images.
| Format | Best for | Notes |
|---|---|---|
| PNG | Icons, sprites, skins | Crisp edges and transparent areas are kept, apart from Fit padding. |
| JPG | Small photographic avatars | No transparency; can soften edges. |
| WebP | Web use | Very small files; check the platform accepts it. |
One master, several sizes
Favicons and icon sets usually need more than one size, such as 16, 32, and 64 pixels. For the cleanest results, work from one larger square master, like 512 × 512, and produce each smaller size from it rather than shrinking a tiny version again. You can make the other sizes with Resize Image using the exact pixel boxes.
Other sizes
If you need a bit more detail, try 128 × 128 or 512 × 512. For other dimensions, use Resize Image.
Frequently asked questions
Is 64 × 64 a good favicon size?
It is one of the sizes commonly prepared for favicons, alongside smaller ones such as 16 and 32 pixels. Check which sizes your site or platform wants.
Can I use this for a Minecraft skin?
Skins are 64 × 64 images, but they follow a specific layout of body parts. Resizing a picture to 64 × 64 gives you the right canvas size, but not that layout, so use a skin editor for the design.
Will my picture look blurry at 64 × 64?
Detailed images lose a lot of information at this size. Crop tightly around one clear subject and avoid fine detail for the cleanest result.
Can I keep a transparent background?
Yes, with PNG output in Stretch or Crop mode. In Fit mode the padding is filled with the white or black background you choose. JPG does not support transparency.
Is it free and do I need to install anything?
It is free and needs no installation. It runs in your browser on a computer or phone, and nothing is uploaded.
Is my picture sent anywhere?
No. Everything happens inside your browser, and the finished file goes straight to your device.
