• Step 1: Select your DIB image(s). Drag and drop or click the upload area on the right. Converter App supports common Windows DIB variants (uncompressed and RLE). You can upload up to 20 files at once, and large images are welcome. Optional: open the settings below to set width and height if you want to resize during conversion.
• Step 2: Wait while we convert your DIB to PNG. Our fast servers create lossless PNGs and preserve transparency when present. If your DIB uses a palette or RLE compression, we turn it into a standard PNG that opens everywhere. Large files may take a moment—keep the tab open and we’ll handle the rest.
• Step 3: Download your result. If you uploaded a single file, click Download to get the PNG. For multiple files, you’ll receive one ZIP containing all converted images. Tip: DIB files often lack an alpha channel; if the source had no transparency, the PNG will be opaque. For smaller web images, consider resizing in the settings before converting.

You can upload up to 20 images at once. Multiple results are delivered as a single ZIP. Large files are supported.
