JPEG to PNG: Lossless Conversion

Quality Preservation

PNG is lossless — once converted, no further quality loss occurs during editing or re-saving.

File Size

PNG files are larger than JPEG. Convert when quality preservation matters more than file size.

Use Cases

Image editing, screenshots, graphics with text, and archival storage.

Transparency

PNG supports transparency, which JPEG does not. Useful for future graphic design work.

Frequently Asked Questions

Is JPEG the same as JPG?

Yes. JPEG and JPG are the same format — JPG is just a shorter file extension from the DOS era's 3-character limit.

Will converting JPEG to PNG improve quality?

It won't restore quality lost in JPEG compression, but it prevents any further loss in future edits.

Why is the PNG file so much larger?

PNG uses lossless compression which preserves all data. JPEG achieves smaller sizes through lossy compression that discards some data.

Is this converter private?

Yes. All conversion happens in your browser. No images are uploaded to any server.
