# JPG to PNG Converter — Free, Batch

Convert JPG images to PNG in batch. 100% in your browser — free, no sign-up, no upload.

## Why convert JPG to PNG?

PNG is a lossless format, so converting a JPG to PNG stops further quality loss when you plan to edit and re-save the image repeatedly. PNG also supports transparency and renders sharp edges and text cleanly, which JPG's compression can blur.

## How it works in your browser

Each JPG is decoded and re-encoded as PNG on a canvas, entirely on your device — nothing is uploaded. Convert a whole batch at once and download them together.

## What to expect

Converting JPG to PNG will not recover detail the JPG already lost — it preserves the current image without adding new compression. Because PNG is lossless, the resulting file is often larger than the original JPG, which is the trade-off for editable, lossless quality.

## When to use PNG

Choose PNG for screenshots, logos, diagrams, and any image you will edit again, or that needs transparency. For sharing photographs where small size matters, JPG or WebP is usually better.

## How to

1. Choose one or more JPG images — they stay in your browser and are never uploaded.
2. Click Convert to re-encode them as lossless PNG.
3. Download the PNGs.
