    Know before you export

    Up to 12 inputs and 60 MiB combined input bytes. Images are decoded one at a time. A failed file is reported without discarding successful outputs. Combined output bytes are limited to 120 MiB. PNG exports ignore lossy quality and target-size settings.

    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.

    Batch processing: common questions

    Which changes can I apply to a batch?

    Choose one action: Compress, Resize, Convert format or Text watermark. The chosen settings apply to each image sequentially. The live preview shows the first image; exported results cover the full batch.

    What happens if one file fails?

    PixelDesk reports the failed file while retaining successful outputs. You can download those outputs individually or in a ZIP. Inputs are limited to 12 files and 60 MiB combined; total output bytes are limited to 120 MiB.
