JPG to PNG Converter

Convert JPG photos to PNG with lossless quality — in your browser.

The JPG to PNG converter turns JPEG photos into PNG files right in your browser. Choose a .jpg, click convert, and download a lossless PNG of the same image in seconds.

PNG is the format of choice when quality matters more than size: it compresses without any loss, supports transparency, and is the standard for images that will be edited further, layered, or printed. Converting a JPG to PNG will not restore detail the JPEG compression already removed, but it guarantees no further degradation happens.

The conversion runs entirely on your device using your browser's built-in encoder — no uploads, no waiting on a server, no size limits beyond what your browser can handle.

Choose an image (JPG). Conversion runs locally in your browser — no upload.

How to use the JPG to PNG Converter

  1. Click 'Choose image' and pick a JPG or JPEG file.
  2. Check the preview and file details.
  3. Click 'Convert'.
  4. Download the resulting .png file.
  5. Use it anywhere lossless quality is required.

Frequently asked questions

Will the PNG look identical to my JPG?

Visually yes — the PNG stores the same pixels without loss. It cannot recover detail that JPEG compression already discarded, but nothing more is lost in the conversion.

Why is my PNG bigger than the JPG?

PNG trades size for losslessness: photographic detail compresses poorly in PNG, so files are often 2–5× larger than JPEG. That is expected — PNG is chosen when quality or transparency matters, not for minimum size.

Can PNGs have transparency?

Yes — PNG supports full transparency, which is why logos and graphics use it. A converted JPG has no transparency to preserve (JPEG does not support it), so the result is fully opaque.
