    How to compare two images visually

    1. Select exactly two still images and confirm which is first and second.
    2. Choose Split view or Side by side, set frame dimensions and adjust the divider or split position.
    3. Review the live comparison, process and download the combined image.

    Know before you export

    Two images are fitted into the same preview frame. This is a visual comparison, not a pixel-difference metric. Side-by-side export uses two frames and doubles the output width.

    Supported files

    Still JPEG, PNG, WebP and AVIF up to 20 MiB and 64 megapixels, plus HEIC where your browser can open it (Safari on Mac, iPhone and iPad). Photos above 24 megapixels are edited at 24 megapixels, and color effects run at up to 12 megapixels. Multi-image tools allow 12 files and 60 MiB of combined input. GIF, SVG, animated images and RAW formats are not supported.

    Compare images: common questions

    Can I compare images with different dimensions?

    Yes. Each picture is fitted into the chosen comparison frame without stretching. Images with different proportions can show padding. Set the frame width and height to suit your comparison.

    Does PixelDesk calculate pixel differences?

    No. This is a visual comparison with a split slider or side-by-side layout. It does not produce a similarity score or pixel-difference metric. Side-by-side export uses two frames and doubles the output width.
