JPG to PNG: Frequently Asked Questions

Does JPG to PNG conversion preserve image transparency?

PNG supports transparency; JPG does not. Converting a JPG to PNG does not create transparency automatically, but the resulting PNG can include it if you add it during editing. Colors and details are preserved because PNG uses lossless compression.

What happens to image quality when converting JPG to PNG?

Visual quality typically matches the source because PNG stores pixels losslessly. File size can be larger than JPG, which uses lossy compression. All processing occurs locally in your browser.

Are there file size limits for JPG to PNG conversion?

Limits depend on your device memory and the image size, not a server quota. Large images may take longer to process, but files stay on your device throughout.

Which browsers support this conversion?

Modern browsers on desktop and mobile support the web APIs used (File and Canvas). No plugins or installs are required.

Can I convert multiple JPG files at once?

Yes. You can queue multiple files and convert them in one session. Each conversion runs locally; download outputs individually or in a batch.
