PNG
PNG (Portable Network Graphics) is a raster image format with lossless compression. It keeps every pixel exactly and supports full transparency, which makes it ideal for screenshots, logos, graphics, and images with text. PNG photos are usually larger than JPG files of the same image.
JPG
JPG is the most common file extension for JPEG images and the standard format for photos. It uses lossy compression that makes files small while keeping good visual quality, and every device, browser, and app can open it. JPG does not support transparency, and each new lossy save can reduce quality slightly.
What changes
The PNG pixels are decoded and written using JPG compression and color capabilities.
- What is preserved
- Pixel dimensions and visible composition are preserved unless resize or crop settings are selected.
- What may be lost
- JPG cannot preserve transparency. Transparent pixels must be flattened against a background color.
- Codec and quality implications
- JPG uses lossy compression. A higher quality or bitrate can reduce new artifacts, but it cannot restore detail already missing from the PNG source.
- Realistic limitations
- Multi-page, layered, animated, camera-raw, or very large images may be flattened, reduced to one frame, or rejected if the decoder cannot safely read them.
Privacy and file retention
Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
