How to convert PNG to JPG and JPG to PNG online
This simple PNG ↔ JPG converter runs directly in your browser. You can turn transparent PNG images into lightweight JPG files for sharing, or convert JPG photos back to PNG when you need better quality or transparency. No account or software installation is required.
Step-by-step: convert PNG to JPG
- Drop your PNG image into the upload area or click to choose it from disk.
- Leave the source format on “Detect automatically” or select PNG manually.
- In the “Convert to” dropdown choose JPG / JPEG.
- Adjust the JPG quality slider (80–90 is a good balance of size and quality).
- Keep the “Compress file” switch enabled if you want smaller output files.
- Click Convert and then download the resulting JPG image.
Converting PNG to JPG is useful when you want to reduce file size for email attachments, messengers, web uploads and any case where bandwidth matters more than pixel-perfect quality.
Step-by-step: convert JPG to PNG
- Upload your JPG / JPEG image using drag & drop or the file picker.
- Set the source format to JPG / JPEG if you do not use auto-detection.
- Select PNG as the output format.
- Click Convert and wait for the PNG version to be generated.
- Download the PNG file using the button or link below the status text.
Converting JPG to PNG will not magically restore lost details, but it is helpful when you need a format that supports transparency or when you want to avoid further compression.
When should I use PNG vs JPG?
- Use JPG for photos, screenshots and images that you share via chat, email or social networks. JPG is smaller and loads faster, especially on mobile networks.
- Use PNG for logos, icons, UI elements, diagrams and images with text or sharp edges. PNG keeps lines and text crisp and supports transparency.
- For web projects, you can keep masters as PNG and export compressed JPG versions for final delivery when you don’t need transparency.
Tips for better quality and smaller files
- For everyday photos, a JPG quality value between 80–90 is usually enough.
- Lower quality (around 60–70) can be used for previews and thumbnails to save space.
- Try to avoid multiple conversions back and forth between formats – each JPG save adds compression.
- Keep an original lossless copy (PNG or the source file) if you plan to edit the image again later.
