Which format should I use?
- JPG — best for photos; small files; accepted almost everywhere, including most government and exam forms. No transparency.
- PNG — lossless; best for screenshots, logos, text and images that need a transparent background. Larger files.
- WebP — modern format, typically much smaller than JPG at similar quality; great for websites. Some older apps and forms don't accept it.
Converting a PNG with transparency to JPG
JPG can't store transparency, so transparent areas are filled with the background colour you choose (white by default).
Need a smaller file? Try the image compressor or resize image to KB. iPhone HEIC photos may not open in every browser — change your camera setting to “Most Compatible” to save JPG.
