Size Reduction

BMP files are bulky due to zero compression — converting to MNG typically produces dramatically smaller files without meaningful quality loss.

Privacy Protection

Your uploaded BMP files are removed right after conversion, and MNG results are deleted from servers within 24 hours — your data stays private.

Bulk Conversion

Need to convert dozens of BMP files? Upload them all and batch-convert to MNG — much faster than processing one at a time.

About formats

BMP (Bitmap) is a raster image file format developed by Microsoft for the Windows operating system, introduced with Windows 3.0 in 1990. The format stores pixel data in a straightforward structure: a file header specifying dimensions, color depth, and compression method, followed by an optional color palette and then the raw pixel array. BMP supports color depths from 1-bit monochrome through 4-bit and 8-bit indexed color to 16-bit, 24-bit true color, and 32-bit with alpha channel. Most BMP files store pixels uncompressed (BI_RGB), though optional RLE compression is available for 4-bit and 8-bit modes. Pixels are arranged in bottom-up row order by default, with each row padded to a 4-byte boundary. One advantage is absolute simplicity — the format has no complex encoding, filtering, or compression layers, making BMP files trivial to read and write programmatically in any language. This simplicity also means BMP images render with zero decoding overhead, useful in scenarios where decompression latency matters. The format's deep Windows integration is another strength: BMP is the native bitmap format for Windows GDI, clipboard operations, and device-independent bitmap (DIB) handling, ensuring first-class support across the entire Windows ecosystem. While BMP's lack of compression produces large files unsuitable for web use or storage-constrained environments, it remains widely used as an intermediate format in image processing, as a clipboard exchange format, and in embedded systems where decoding simplicity outweighs file size.
Developer: Microsoft
Initial release: 1990
MNG (Multiple-image Network Graphics) is an animation and multiple-image format designed as the animated counterpart to PNG, with its specification reaching version 1.0 on January 31, 2001. Developed by Glenn Randers-Pehrson and members of the PNG development community, MNG extends PNG's capabilities with support for frame-based animation sequences, slide shows, complex sprite overlays, and JNG (JPEG Network Graphics) frames for lossy compression of photographic content within the same container. An MNG file consists of a series of chunks (following PNG's chunk-based architecture): MHDR and MEND chunks bookend the datastream, with embedded PNG or JNG images as individual frames and control chunks (DEFI, FRAM, LOOP, ENDL, TERM, BACK, BASI, CLON, PAST, DISC, SHOW) directing playback timing, looping behavior, layer compositing, and memory management. The format supports both full-frame replacement and delta (difference) updates for efficient encoding of animations with static backgrounds, as well as object-based animation where sprites are defined once and repositioned across frames. One advantage is technical sophistication: MNG provides a level of animation control that GIF and APNG cannot match — frame-accurate timing, nested loops, conditional branches, interframe compression, and mixed lossy/lossless content within a single animation. The PNG-based foundation ensures lossless quality with full alpha transparency for each frame. MNG is supported by ImageMagick, GIMP, and various media players, though browser support was limited, which led to APNG's emergence as a simpler alternative for web animation.

Frequently Asked Questions

Why convert BMP to MNG?

MNG provides PNG-based multi-frame output — useful when your BMP needs animation capabilities with lossless compression quality.

What software reads MNG format?

Konqueror, XnView, ImageMagick, GIMP. Most modern operating systems also have built-in support or free viewer options available.

Is the conversion process fast?

BMP to MNG conversion usually finishes in a few seconds. Larger files may take slightly longer, but the cloud-based processing keeps things efficient.

How much smaller will the MNG be?

Depending on image content and MNG compression, expect file sizes 50-95% smaller than the original BMP. Photographic content typically compresses the most.

Can I use this on Mac and Linux?

The converter is entirely browser-based — it works on macOS, Linux, Windows, and any other platform with a modern web browser. No OS-specific software needed.

Are my files safe during conversion?

Convertio uses encrypted connections for all transfers. Your BMP uploads are deleted immediately after conversion, and MNG downloads are removed within 24 hours.
