BMP (Bitmap Image File) uses uncompressed encoding and is best for legacy software compatibility, raw pixel data transfers, and simple image processing tasks. PNG (Portable Network Graphics) uses lossless encoding and excels at graphics with sharp edges, text overlays, screenshots, and images requiring transparent backgrounds. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
Convert BMP images to PNG format in your browser. Lossless, private, and completely free — no uploads needed.
Yes — archive BMP originals before batch-converting. Re-converting from PNG back to BMP never restores discarded data.
Seconds for typical files on a modern device; large files scale with size and CPU. Conversion speed depends on the machine, not the formats — close heavy tabs for big batches.
From uncompressed to lossless: quality is preserved as far as the formats allow.
PNG to BMP
PNG to BMP output is not produced here — browsers have no BMP encoder, so Canvas conversion fails locally instead of downloading. Convert PNG to PNG/JPG/WebP instead — local, unlimited saves.
Bulk Image Format Converter
Convert image batches between JPG, PNG, WebP, and AVIF outputs (JPEG/PNG/WebP/AVIF/HEIC/HEIF/GIF/BMP/ICO/SVG inputs; HEIC via heic2any, SVG rasterized at intrinsic size or 1024px fallback) with a quality slider (10–100, default 80). Pair pages (?from/?to) preset the output. Flat ZIP renamed per file — local, 5-file guest batches, 25 signed-in, 500 Pro.
Image Format Converter
Convert one browser-decodable image to PNG, JPG, or WebP — the only outputs canvas can encode. HEIC/SVG/JXL/TIFF and other exotic targets fail honestly instead of pretending. Nothing is uploaded; every conversion runs in your browser.
