Convert JPG to PNG Free (No Upload, No Sign-Up)

JPG is the end of the line for editing — every save loses a little more quality. Converting to PNG stops the bleeding: from here on, saves are lossless. People usually convert when they need to edit a JPG further, or when a tool or workflow requires PNG.

Use the free tool: Image Batch Converter — up to 10 images per batch, processed in your browser.

Steps

1. Open the Image Batch tool.

2. Add your JPG images — up to 10 per batch on the free version.

3. In the Format selector, choose PNG.

4. Convert and download the PNG files.

What conversion can and can't do

Conversion can't restore detail the JPG already discarded — compression is one-way. Whatever artifacts and softness are baked into the JPG carry over exactly; the PNG just preserves them without adding new loss. It also doesn't add transparency: JPG has no alpha channel, so the PNG comes out fully opaque.

And expect a bigger file. PNG stores every pixel exactly, so output typically runs roughly 2–5x the size of the JPG. The real reason to convert isn't size or looks — it's to stop further lossy saves, and to get a format that tools requiring PNG will accept.

Troubleshooting

• PNG is much bigger? Expected — PNG is lossless. If size matters, stick with JPG or compress afterward.
• Still see JPG artifacts? Those were baked into the JPG. Conversion preserves them exactly; it can't clean them up.
• Need transparency? Converting a JPG can't create it — the PNG will be fully opaque.
