Frequently asked questions
How do I open a PNG file?
PNG (Portable Network Graphics) is a lossless raster image format standardized in 1996 as a patent-free replacement for GIF. It preserves every pixel exactly, supports full alpha transparency, and is the default choice for screenshots, logos, and graphics with sharp edges or text. If a device refuses to open it, the fastest fix is converting it to a more universal format with the converter above.
Is converting PNG files free?
Yes — 10 conversions a day with files up to 200 MB, free, with no signup and no watermarks.
Why is my PNG larger than the original file?
PNG is lossless, so it stores every pixel exactly. Converting a compressed photo (like JPG or WebP) to PNG usually increases file size — that is expected and means no quality was lost.
