Frequently asked questions
About BMP to PNG
BMP to PNG converts old or oversized bitmap images into a modern lossless format. BMP files are often very large because they store raw pixel data with little or no compression. PNG keeps the image sharp while making it easier to upload, email, edit, or archive. This is useful for old screenshots, exported diagrams, scanned images, legacy software output, and Windows bitmap files that web tools reject. PNG keeps sharp text and flat colors especially well. For photos, JPG or WebP may be smaller. For screenshots and graphics, PNG is usually the better replacement for BMP.
