Convert Image to PNG

The PNG format (Portable Network Graphics) uses lossless compression, unlike JPG which degrades the image with every save. Ideal for logos, screenshots, technical diagrams, or illustrations with text. Every pixel remains true to the original. Our converter turns your JPG or WEBP files into high-quality PNGs, directly in your browser, without altering sensitive data. If you work with sharp graphics or flat color areas, PNG is indispensable.

Only PNG (and WEBP) support native transparency with an alpha channel. Ideal for overlaying logos, creating user interfaces, or making compositions. If you convert an image with transparent areas (e.g., an animated GIF or an original PNG) to another format, transparency will be lost. Our tool preserves the alpha channel when converting to PNG. You can also take a white JPG and turn it into a PNG with adjustable background via canvas. For web designers, transparent PNG is an indispensable ally.

To preserve invoices, digitized contracts, or legal screenshots, PNG guarantees that no information is altered by destructive compression. Moreover, converting an image to PNG with our local tool eliminates any risk of espionage. EXIF metadata (GPS location, etc.) is often removed during the canvas process, increasing confidentiality. Unlike PDF or JPG, PNG offers perfect pixel integrity, ideal for visual evidence.

Raw PNGs can be heavy. Fortunately, several methods allow weight reduction without quality loss: reducing the number of colors (PNG-8 instead of PNG-24), optimizing metadata, or using tools like pngquant. With our converter, you can go from JPG or WEBP to PNG and then edit the file again. For the web, sometimes WEBP (more modern) is preferred, but PNG remains the king of transparency and compatibility. Our tool lets you easily switch between formats, staying 100% local.

✅ No registration, no size limits. Processing is instant and private.

Most online tools send your photos to their servers, potentially exposing your data to leaks or unwanted use. Our converter works entirely inside your browser: no image is ever sent to an external server. Processing is local thanks to Canvas and FileReader APIs, guaranteeing absolute confidentiality. Your private photos, sensitive documents, or creations remain on your computer. This is the "Zero-Knowledge" approach applied to image conversion.
