JPG to PNG FAQ
Will the file size increase?
Yes, typically. PNG files are larger than JPG because they use lossless compression. This is a tradeoff for higher editing quality.
Does converting add transparency?
No. The original JPG pixels are preserved as-is. However, the PNG format allows you to add transparency in a design tool afterward.
Is this processed locally?
Yes. The conversion uses your browser's Canvas API. No data is sent to any server.
