Note: While this guide focuses on converting JPG to PNG, our app also supports PNG to JPG conversion. Converting PNG to JPG can help reduce file size since JPG uses lossy compression. However, keep in mind that any transparency in a PNG image will be replaced with a solid background when converted to JPG.

Converting JPG files to PNG is common when you need lossless image quality or plan to work with transparency. Below, we explain when conversion makes sense, why you might need it, and how to do it securely within your browser.

Core Difference: JPG uses lossy compression, which reduces file size but sacrifices some quality. PNG uses lossless compression, meaning it preserves image quality exactly and also supports transparent backgrounds.

Why Convert JPG to PNG?

There are several practical reasons to switch from JPG to PNG:

• Maintain Quality During EditingEach time a JPG is edited and saved, it undergoes compression again, which gradually lowers image quality. PNG files retain their original quality no matter how many times they are saved, making them ideal for repeated editing.
• Work with TransparencyIf you plan to remove backgrounds or create transparent areas, PNG is required. JPG does not support transparency—every pixel must contain a color value.
• Improve Graphics and Text Clarity PNG is better suited for images with sharp edges, text, logos, diagrams, and UI elements. JPG compression often introduces blur or artifacts around these details.

Important: Converting a JPG to PNG does not restore quality already lost due to JPG compression. The PNG will accurately preserve the image in its current state—including any compression artifacts.

How to Convert JPG to PNG

Our tool makes conversion quick and secure:

1. Upload your file: Select Choose File to upload a JPG image.
2. Convert: Click the CONVERT button to process the image instantly in your browser.
3. Download: Save your new PNG file using the provided download link.

Pro Tip:PNG files are often significantly larger than JPG files—sometimes 5–10 times bigger. This increase is normal because PNG does not compress images in a lossy way.

Common Use Cases

Typical Scenarios

• Photo editing workflow: Convert to PNG before making extensive edits, then export the final version as JPG for sharing.
• Graphic design projects:: Convert photos to PNG before adding them to design software or combining them with transparent elements.
• Image archiving: Store important images as PNG to avoid further quality loss from repeated saving.
• Documentation screenshots: Use PNG for sharper text and cleaner edges in guides and manuals.

Understanding Transparency/h4>

A frequent misconception is that converting a JPG to PNG automatically creates transparency. It does not. The converted PNG will keep the same solid background as the original JPG.

To create transparency, you must:

1. Convert the JPG to PNG (to preserve quality during editing).
2. Use photo editing software to remove the background.
3. Save the edited image as PNG to retain transparent areas.

The conversion prepares your file for transparency work, but background removal must be done in image editing software such as Adobe Photoshop, GIMP, or an online editing tool.

Privacy and Security

Your files remain completely private:

• Local processing: All conversions occur directly in your browser.
• No uploads: Your images are never sent to a server
• No storage: We do not store or access your files.
• Original files unchanged: Your source JPG remains untouched.

By using WebAssembly technology, image conversion runs entirely on your device—providing fast results without compromising privacy.
