What is the JPG to PNG Converter?
The JPG to PNG tool converts JPG/JPEG photos into PNG — a lossless format with transparency support — entirely inside your browser. PNG is the right choice for UI mockups, logos and images with sharp text or edges that JPG artefacts would blur.
Conversion runs locally, so photos with personal data or client artwork never leave your device.
How to use the JPG to PNG Converter
- 1Drop your .jpg files onto the upload area.
- 2Preview the thumbnail to confirm the right image.
- 3Click "Convert to PNG".
- 4Download the result — the original filename is kept with a .png extension.
Key features
- Client-side conversion — no uploads
- Batch conversion of multiple JPGs
- Preserves original resolution and colour depth
- Alpha channel added for later background removal
Important notes
- PNG files are usually 2–5× larger than the equivalent JPG because PNG compression is lossless.
- Conversion cannot restore detail the JPG already discarded — it preserves exactly what is there.
Frequently asked questions
Does the PNG have transparency automatically?
The alpha channel is added, but pixels start opaque — use an editor or the Remove Background tool to make areas transparent.
Can I convert HEIC or WebP the same way?
This tool handles JPG → PNG. Use the other ToolSink converters for different formats.
