About JPG to PNG Converter
Convert JPG to PNG instantly in your browser with no file uploads and no server processing. PNG (Portable Network Graphics) is a lossless format that preserves every pixel of your image with no quality degradation, making it ideal for screenshots, logos, icons, and images that require transparency. Unlike JPG, PNG supports an alpha channel for transparent backgrounds. Conversions are fast and accurate even for large files up to 10MB. Batch convert up to 20 images at once and download them individually or as a single ZIP archive. Your images never leave your device — all processing happens locally in the browser with zero privacy concerns. Whether you need PNG for web graphics, document editing, or preserving image quality for further editing, this tool handles it reliably. The PNG output is fully standards-compliant and will open correctly in every modern browser, image editor, and operating system. No account or software installation is required.
Frequently Asked Questions
- Will converting JPG to PNG improve image quality?
- No. PNG is lossless, so the output is an exact copy of the decoded JPG pixels. Any quality loss that occurred when the JPG was originally saved cannot be recovered.
- Does PNG support transparency?
- Yes. PNG supports an alpha channel. However, if your source JPG has no transparency data, the PNG output will have a fully opaque background.
- Is there a file size limit?
- Each file must be under 10 MB. You can convert up to 20 files at once.
