JPG to PNG Converter

JPG (or JPEG) uses lossy compression to create smaller file sizes by discarding some image data, which can cause artifacts around sharp edges. PNG uses lossless compression, preserving every pixel exactly but producing larger files. PNG also supports transparent backgrounds, while JPG does not.

PNG preserves the original image data without further degradation, but it cannot restore quality already lost from JPG compression. However, PNG will not introduce new artifacts and is ideal for images with text, logos, or sharp edges where JPG artifacts are visible.

No. All image processing is done entirely in your browser using the Canvas API. Your images never leave your device, ensuring complete privacy and security.

The maximum allowed file size is 50 MB. If your file exceeds this limit, you will see a clear error message.

Yes, PNG supports full transparency (alpha channel). However, when converting from JPG — which does not support transparency — there is no transparency data to preserve. The resulting PNG will have a white background by default at the positions that were opaque in the JPG.

Yes, PNG files are typically 2-5 times larger than equivalent JPG files because PNG uses lossless compression. The exact size depends on image complexity — photographs with many colors compress less efficiently in PNG format.

Currently, this tool processes one image at a time. You can use the "Convert Another" button after each conversion to process additional files without refreshing the page.

PNG is ideal for screenshots, logos, icons, infographics, images with text, diagrams, and any image where preserving sharp edges and exact colors is important. For photographs, JPG or WebP are usually more storage-efficient.

Yes, the tool works on any device with a modern browser, including smartphones and tablets. The responsive interface adapts to your screen size and supports touch-based file selection.

PNG is excellent for web graphics, logos, and UI elements where quality and transparency are important. For photographs, consider using JPG or WebP for faster page loads. Using a mix of formats optimized for each image type is a best practice for web performance.

The Canvas API strips most EXIF metadata during conversion. If you need to preserve metadata like camera settings or GPS coordinates, consider using a dedicated image editing application instead.

Screenshots often contain text, UI elements, and sharp edges that suffer from JPG compression artifacts. PNG preserves these elements with pixel-perfect accuracy, making it the preferred format for documentation, presentations, and design reviews.
