常见问题
Quick answers.
›Will converting JPG to PNG improve image quality?
No. While PNG is a lossless format, the conversion cannot recover detail already lost to JPG compression; it simply prevents further quality degradation during subsequent saves.
›Are my images private?
Yes. Processing happens entirely in your browser's memory. Your files are never sent to our servers or stored anywhere on the internet.
›Can I convert multiple images at once?
Yes. You can select multiple JPG files to process them in a batch, and the tool will generate a PNG for each individual upload.
›Will the file size change?
Usually, yes. PNG files are typically larger than JPGs because they store image data without lossy compression algorithms.
