    Resize any picture to exactly 512 × 512 pixels

    The output is always 512 × 512 px – the size used for app icons, game assets, AI image inputs and Discord emojis/stickers. 512 × 512 is the base size for Android adaptive icons, Steam and Discord assets, and many AI tools expect square 512 px inputs.

    Choose PNG if you need transparency preserved; JPG for photos. The tool downsizes in steps rather than in one jump, which keeps edges and text sharper than a basic one-shot resize, and it reads the camera orientation so phone photos come out the right way up.

    Steps

    1. Add the image. Click the sheet or drag the file in. JPG, PNG, WebP, HEIC, GIF, BMP and AVIF are accepted; several at once is fine.
    2. Confirm 512 × 512. The width and height are pre-filled. Switch the unit to cm or mm if your spec is in print units – the pixel size is shown underneath.
    3. Choose what happens to a different shape. Crop to fill (default), Fit with white bars, or Stretch.
    4. Optionally set a KB limit. If the site also caps the file size, type it; quality is adjusted so the file fits at these exact dimensions.
    5. Resize and download. One image downloads directly, several as a ZIP.

    Frequently asked questions

    How do I resize an image to 512 × 512 pixels?

    Add the image, keep 512 and 512 in the width and height boxes, choose how to handle a different shape (crop, fit with white bars, or stretch) and press Resize. The file downloads at exactly 512 × 512 px.

    Will a non-square photo be distorted?

    Not unless you choose “Stretch”. The default “Crop to fill” trims the longer side from the centre; “Fit, white bars” keeps the whole image and pads the short side with white.

    Can I also keep the file under a size limit?

    Yes. Enter a KB number in “Max size” and the JPG quality is lowered until the 512 × 512 image fits – the dimensions are never changed to reach it.

    Does resizing upscale small images?

    It will output 512 × 512 px even from a smaller source, but detail cannot be invented – a 200 px picture enlarged to 512 px will look soft. Start from the largest original you have.

    Is the image uploaded?

    No. Resizing happens in your browser; nothing is sent to a server.
