How do I convert PNG to DJVU online?

Upload your PNG file, select DJVU as the target format, choose desired DPI or compression level if advanced options are available, then click Convert. Once processing completes, your DJVU file downloads automatically; on LetsConvert, you can also upload multiple PNGs for batch conversion.

Why should I convert PNG to DJVU instead of keeping PNG?

DJVU is built for scanned documents and multi-page books: its wavelet and JBIG2 compression can make files significantly smaller than PNG while keeping text sharp. PNG preserves fine image detail and transparency, but yields large document scans. Convert to DJVU when the final use case is document archival, e-book distribution, or sharing on platforms that support DjVu viewers.

What happens to transparency, color profiles, and DPI when converting from PNG to DJVU?

PNG alpha transparency is flattened in DJVU, as the format doesn't support per-pixel alpha; transparent areas are blended with the background or removed. DPI metadata is carried over and can be overridden. Color profiles are converted to the closest available DjVu color space, and high-resolution photos may undergo lossy wavelet compression, while text and line art are encoded losslessly via JBIG2.
