Higher percentages preserve detail but increase file size. Lower settings use aggressive compression, ideal for fast-loading web graphics.
The main benefit is file size optimization. PNG files, especially high-resolution ones, can be quite large because they use lossless compression. JPG uses lossy compression which is significantly more efficient for photographs and detailed images. Converting to JPG can reduce file sizes by up to 80% or more, making them much easier to share via email or upload to social media platforms.
Yes, our conversion engine maintains the exact pixel dimensions (width and height) of your original PNG file. We do not stretch or warp your image during the process. The only thing that changes is the underlying file format and data encoding. Your resulting JPG will be a pixel-perfect, proportional clone of your source PNG, just in a different and more compact format.
