JPG to PNG conversion (private, fast, and browser-based)
JPG (or JPEG) is one of the most common image formats for photos and web sharing because it compresses images efficiently.
PNG is a lossless format that is often preferred for editing, design workflows, and crisp graphics. This JPG to PNG Converter
runs directly in your browser, so your images are processed locally on your device.
How to use this JPG to PNG Converter
- Upload: Click Upload (or drag and drop) to add up to 20 JPG/JPEG files.
- Convert: The tool converts each file to PNG automatically and shows the output size and pixels.
- Download: Download PNG files individually, or use Download All (ZIP).
- Clear: Click Clear to remove the entire queue and reset the tool.
Important note about transparency
JPG does not support transparency. Converting a JPG to PNG keeps the same visible pixels, but it does not create a transparent
background. If you need transparent backgrounds, you must remove the background first using a dedicated background remover tool.
What is JPG, and why convert JPG to PNG?
JPG (JPEG) uses lossy compression, which means it reduces file size by removing some image data. This is great for photos, but
repeated re-saving or heavy compression can introduce artifacts such as blocky edges and color banding.
PNG is lossless, meaning it preserves pixels without additional compression damage. This makes PNG useful when you plan to edit an
image, add text overlays, use it in design software, or keep the best possible pixel accuracy for graphics and UI screenshots.
Common use cases
- Editing workflows: Convert JPG photos into PNG for design tools that prefer lossless assets.
- Graphics and screenshots: PNG can keep sharper edges for UI elements and text-heavy images.
- Archiving: Save a stable copy for future edits without adding more JPEG artifacts.
- Compatibility: Some software pipelines and templates work better with PNG.
How this tool works (simple explanation)
This converter loads your JPG image into a browser canvas and then exports it as a PNG file. The conversion happens locally in
your browser, so it does not require uploading files to a server.

Best practices for better results
- Use PNG when editing: If you will add text, crop, or re-export multiple times, PNG helps avoid extra JPEG artifacts.
- Keep JPG for photos on the web: If your goal is smaller file size, JPG is often better for final publishing.
- Batch download with ZIP: For many files, Download All (ZIP) saves time.
- Keep the original: Always keep the original JPG if you need the smallest size for sharing later.
Privacy and security
This tool is designed to be privacy-friendly. Conversion happens in your browser using JavaScript and canvas processing.
Your images are not uploaded to a server by this page.
Troubleshooting
- Upload not working: Make sure JavaScript is enabled and your browser allows file access.
- Wrong file type: This tool accepts JPG/JPEG files only.
- ZIP download fails: Try fewer images or refresh the page if the ZIP library did not load.
- Large images feel slow: Very large files may use more memory. Convert in smaller batches.
