Resize an image to 512 × 512 pixels for icons, stickers, and avatars
Five hundred and twelve pixels is the go-to size for app icons, chat stickers, and profile pictures. It is square, a power of two, and large enough to look crisp when scaled down. This free online tool turns any picture into exactly 512 × 512 in your browser, with no app to install and no upload.
Below you will find where 512 × 512 is commonly required, how to design for small and rounded shapes, whether to choose PNG or JPG, and how to keep a logo or face from being cut off. The 512 × 512 target is already filled in for you.
Where 512 × 512 is required or recommended
Requirements change over time, so confirm them on the platform. These are the places where this size most often appears.
- Android and web app icons. Google Play asks for a 512 × 512 icon, and progressive web apps commonly include a 512-pixel icon in their manifest.
- Chat stickers. Messaging apps such as WhatsApp and Telegram base their sticker formats on a 512-pixel canvas.
- Community and server icons. Platforms such as Discord recommend 512 × 512 for server icons so they stay sharp when scaled down.
- Profile pictures. A 512-pixel square gives plenty of room for sites that crop avatars into circles or rounded squares.
- Logos for small spaces. A tidy 512-pixel logo can be scaled down to favicons, badges, and thumbnails.
Converting, resizing, and what the tool really does
Getting an icon to 512 × 512 is a resize of the picture's pixel dimensions. If you also choose a different output format, such as saving a JPG as a PNG, it is converted as well. Both happen in one step, entirely in your browser, so it works like a lightweight online image converter and resizer without anything to download.
Designing for small, round, and rounded shapes
Many platforms crop icons into circles or rounded squares, or show them at a fraction of this size. A few habits help.
- Keep the important part of the picture near the center, since circular masks trim the corners.
- Use bold, simple shapes and high contrast. Fine detail turns to mush at small sizes.
- Choose Crop for photos so the 512 × 512 square is completely filled.
- Choose Fit when a logo must stay whole, and pick a white or black background to match your design.
Step by step: making a 512 × 512 icon
- 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 512 and 512, and you can still edit them if you need something slightly different.
- Pick a Resize mode. Crop fills the whole icon for photos, while Fit keeps a logo or sticker intact with a white or black background.
- Choose an Output format. PNG is the usual choice for icons and stickers because it keeps edges sharp. JPG suits photographic avatars, and WebP is common for stickers where it is accepted.
- Click Resize Image, compare the Original and Resized previews and their details, then click Download Image.
Nothing leaves your device. The picture is decoded, resized, and saved by your own browser.
PNG or JPG for icons?
PNG keeps sharp edges and flat colors exactly, and it can hold transparency, which makes it the safest choice for logos and stickers. JPG produces smaller files for photographic images but can show blurry artifacts around text and hard edges. At 512 × 512 even a PNG is usually tens to a few hundred kilobytes, so file size is rarely a problem.
| Format | Best for | Notes |
|---|---|---|
| PNG | Icons, logos, stickers | Crisp edges and transparent areas are kept, apart from Fit padding. |
| JPG | Photographic avatars | Small files; no transparency. |
| WebP | Stickers and web use | Small files with good quality; check the platform accepts it. |
Check before you upload
- Confirm the platform's accepted formats, since some icon and sticker uploads allow only PNG or WebP.
- Look at its file size limit and compare it with the size shown beside the Resized preview.
- Check whether transparency is allowed or expected, and keep the background transparent only with PNG output.
- View the result at a small size, as it will be seen next to other icons rather than on its own.
Other sizes
For smaller icons try 128 × 128 or 64 × 64. For larger artwork see 1000 × 1000, and for any other dimensions use Resize Image.
Frequently asked questions
Is 512 × 512 the right size for an app icon?
Google Play asks for a 512 × 512 icon, and web apps often include one too, but each platform has its own rules about format and shape. Check the current guidelines before you submit.
Can I make a sticker at 512 × 512 here?
You can produce a 512 × 512 PNG or WebP image, which is the canvas size many sticker formats use. Some apps add rules on file size or format, so check those before uploading.
Does the tool keep transparent backgrounds?
With PNG output, transparent areas are kept in Stretch and Crop modes. In Fit mode the padding is filled with the white or black background you choose. JPG does not support transparency.
Is it free, and is there an app to install?
It is free, and no app is needed. It works in the browser on a computer or phone, and nothing is uploaded.
What if my image is smaller than 512 × 512?
It will be enlarged to the exact size, but enlarging cannot add detail, so very small sources can look soft.
Is my picture sent to a server?
No. Everything happens inside your browser, and the finished file goes straight to your device.
