Frequently Asked Questions
Can I convert a JPG with a white background into a transparent PNG?
Yes! Use our Transparency Engine and select 'Remove White Background'. The converter will automatically turn the white backdrop of signatures, logos, and stamps into a true transparent alpha channel.
Does converting from JPG to PNG improve photo quality?
Converting to PNG stops further compression degradation. PNG is completely lossless, making it the ideal format for editing, transparency, text graphics, and archival storage.
Does this tool inject 300 DPI metadata headers into PNG files?
Yes. Our binary encoder injects the official PNG 'pHYs' chunk calibrated to 300 DPI (11,811 pixels/meter), ensuring photo labs and official print portals recognize exact print dimensions.
Can I convert Apple iPhone HEIC photos directly on Windows or Android?
Yes. Our client-side WebAssembly engine decodes Apple HEIC and HEIF photos directly in your device browser, outputting uncompressed PNG files compatible with all platforms.
Are my personal files uploaded or saved on any remote server?
No. All file decodings, color composites, compression calculations, and ZIP packaging execute 100% locally inside your browser memory (RAM) with total privacy.
