JPG to PNG Converter

Convert JPG photos to lossless PNG, drag in one or many files and download edit-friendly copies with no further generation loss. Converted in your browser; nothing is ever uploaded.

Converted images appear here, each with a download button.

How it works

Each JPG is decoded and redrawn onto an HTML canvas, then exported as a lossless PNG. PNG supports transparency and avoids the generation loss that comes from re-saving JPEGs, which makes it the better format for editing, logos and screenshots.

Because PNG is lossless, the converted file is usually larger than the original JPG, that is the trade-off for an exact, edit-friendly copy.

Your images are decoded and converted entirely in your browser, nothing is ever uploaded.

What this does

A JPG to PNG converter turns JPG photos into lossless PNG copies that avoid further quality loss when edited or re-saved.

How to use it

  1. Drop in one or more JPGs.
  2. Each is converted to PNG.
  3. Download the lossless copies.

How it works

The image is re-drawn to a lossless PNG in your browser, so nothing is uploaded. It cannot recover detail already lost to JPEG, but it stops any future loss.

Example

A re-edited logo.jpg becomes a stable logo.png master.

Frequently asked questions

Why convert JPG to PNG?

PNG is lossless and supports transparency, so it avoids the quality loss that comes from repeatedly re-saving a JPEG. That makes it better for editing, logos and screenshots.

Will converting improve the image quality?

No, it cannot recover detail already lost to JPEG compression, but it stops any further loss from future edits and saves, giving you a stable master copy.

Can I convert multiple photos at once?

Yes. Select or drop several JPGs and each is converted independently, each with its own download button.

Are my photos uploaded?

No. Every image is decoded and converted entirely in your browser using an HTML canvas; nothing is sent to any server.
