• Start the repair process by selecting "Repair All". The software will analyze the imported files and identify recoverable image data.

  

• Preview the repaired PNG files before exporting them with the "Preview" button. Check important details such as edges, colors, transparency, text, and other areas that were affected by the corruption.

  

• Select the repaired images you want to keep and choose "Save". Select a separate destination folder when possible so the original corrupted PNG files remain unchanged.

  

A repair tool cannot guarantee complete recovery when the original image data has been permanently destroyed. Keeping the original corrupted file untouched gives you another recovery option if the first attempt does not produce the expected result.

Online repair is convenient, but it is not suitable for every corruption scenario. Very severe damage may require a desktop PNG repair toolkit with more advanced recovery capabilities.
