FAQ
- Q: Will converting JPG to PNG degrade image quality? A: No. PNG is a lossless compression format, and the conversion process will preserve as much of the original JPG’s image detail as possible.
- Q: Why is the converted PNG file larger than the original? A: This is because PNG uses a lossless compression algorithm, while JPG uses lossy compression. Lossless formats generally require more space to store pixel information.
- Q: Is there a limit to the number of files for conversion? A: This tool has been optimized for large-batch scenarios, supporting the import of hundreds of images at once without worrying about crashes.
