Why Convert JPEG to PNG?
JPEG and PNG are both widely supported image formats, but they serve different purposes. JPEG uses lossy compression — it discards some image data to keep file sizes small, which is perfect for photos. PNG uses lossless compression, keeping every pixel intact and supporting full transparency.
You'll want to convert JPEG to PNG when you need to:
- Preserve sharp edges on text, logos, or diagrams without compression artifacts
- Add a transparent background (JPEG has no transparency support)
- Edit an image repeatedly without quality loss across saves
- Use the image in a design that sits on a coloured or patterned background

Frequently Asked Questions
Does converting JPEG to PNG improve quality?
No. The conversion stores the existing pixels losslessly, but any quality reduction from the original JPEG compression is already permanent. Think of it as putting a photo in a better frame — the frame is better, but the photo inside is unchanged.
Will the PNG file be larger than the JPEG?
Almost always, yes. Because PNG doesn't discard data, its file sizes are typically 2–5× larger than an equivalent JPEG. For web photos, JPEG or WebP is usually the better choice. For graphics and images needing transparency, PNG wins.
Can I batch-convert multiple JPEGs at once?
Yes — our Image Converter supports uploading multiple files and converting them all in one go. All files are processed locally in your browser; nothing is uploaded to a server.
What if I need an even smaller file?
After converting, run the PNG through our Image Compressor to reduce the file size without visible quality loss.
