What this tool does
This tool converts JPG/JPEG images to PNG format. PNG uses lossless compression for the decoded pixels, so every pixel is preserved exactly as decoded from the original JPG. Unlike JPG, PNG supports transparency (alpha channel), making it ideal for graphics, logos, and images that need transparent backgrounds. Converting to PNG does not restore detail previously discarded by JPG compression. The conversion process preserves EXIF orientation data and maintains 1:1 pixel fidelity of the decoded image.
Trust and privacy are built into the workflow. Nothing leaves your device during processing, and there is no account setup. That makes it suitable for personal photos, client assets, product shots, and everyday creative work.
How to convert to PNG
- Upload or drag your file into the tool above.
- Choose output settings such as quality, size, or page options.
- Preview the result before you download.
- Download the finished file for web, email, print, or sharing.
Tip: start with balanced quality settings rather than maximum compression so detail stays intact for web and sharing.
Key benefits
- PNG files are typically 2-5x larger than JPGs - only convert if you truly need PNG features like transparency
- PNG stores decoded pixels with lossless compression — it preserves what is already in the JPG after decoding
- If your image has a solid background, the conversion won't automatically make it transparent - use an image editor for that
- PNG is ideal for images with sharp edges, text overlays, or graphics with few colors
- For photographs you'll share online, JPG is usually better for smaller file sizes
- PNG supports lossless compression, so you can edit and re-save without quality degradation
- Use PNG when you need to preserve exact colors and avoid compression artifacts
Privacy note: no files leave your device. All convert steps run locally in your browser.
