How to Convert PNG to BMP

Change My File is the best online software to convert PNG to BMP for free without compromising image quality. Whether you’re a graphic designer, a developer, or just someone dealing with different image formats, it’s essential to have tools that allow seamless file format conversion. PNG and BMP are both widely used image formats, each serving distinct purposes. While PNG is known for its compression and transparency support, BMP is favored for raw, uncompressed image quality ideal for certain applications.

To make converting files quick and hassle-free, we've developed an easy-to-use online tool. Just follow these steps to convert your PNG file to a BMP file:

Open your browser and go to changemyfile.com.
On the homepage, click on the ADD FILE option.
Your device’s file manager will open—select the PNG file you want to convert.
You can upload up to 10 files at once, as long as their total size is under 50 MB.
After uploading the PNG file(s), click on CONVERT TO and choose BMP from the list of formats.
Once selected, hit CONVERT NOW. Within seconds, your file will be converted.
Download the resulting BMP file and use it as needed.

These simple steps allow you to convert PNG to BMP in seconds—and best of all, it’s completely free!

PNG to BMP Conversion

PNG and BMP files both handle image data but in different ways. PNG (Portable Network Graphics) files are compressed and support transparency, making them ideal for web use and images with clear backgrounds. BMP (Bitmap) files, on the other hand, are uncompressed and retain raw pixel data, offering better quality for editing or printing purposes.

BMP files are often larger in size compared to PNG, but their simplicity and high quality make them ideal for certain applications like software development, image processing, or archival purposes.

Why Convert PNG to BMP

Converting PNG to BMP ensures compatibility with software that requires uncompressed image data. BMP files are often preferred for legacy applications, image editing programs, or Windows-based systems that rely on raw pixel data. Additionally, BMP format is beneficial for detailed image analysis or printing where maximum quality is crucial.

By converting PNG to BMP, you gain better control over the image's color and detail without compression artifacts. It also ensures smooth compatibility with platforms and tools that might not fully support PNG features like alpha transparency.

Is it Safe to Convert PNG Files to BMP

Absolutely. Our tool at Change My File ensures secure uploads and fast, lossless conversions. Your image files are not stored after processing, ensuring your privacy and data security. Whether you're converting a single file or multiple images, you can trust that the process is safe, quick, and efficient.

Overview

These files are commonly termed as ‘ping' and they store the raster files using lossless compression. It came into existence in order to replace the GIF file format as they both have the ability to show transparent backgrounds. Furthermore, it was an enhanced and improved version of Graphics Interchange format. It supports different types of photos. The first one is palette-based photographs that can either have palettes of 24-bit RGB or 32-bit RGBA colours. Second is grayscale images which may or may not have an alpha channel for transparency. Lastly, there is a full-colour non-palette which is based on RGB/RGBA pictures. There is one limitation of this type. It does not support animation like GIF. Besides this, it is non-patented which means there are no copyright limitations.

Technical description

The expanded features like 8- bit channel for transparency and 24- bit RGB support make PNG more popular. The files stores in this format allow the fading of colours from opaque to transparent which is not present in the preceding format. CMYK does not offer support to this extension as it was developed for transferring of files over the internet, not for professional-quality print graphics. It stores information like textual comments, integrity checks and encoded basic pixels in its extensible structure of chunks. It always starts with an 8-byte signature followed by a series of chunks. A chunk furthermore comprises of four parts- length (4 bytes), chunk type (4 bytes), chunk data (length bytes) and CRC- Cyclic redundancy checksum or code (4 bytes).

Overview

BMP format is used for Raster images. These images contain a grid of pixels and each pixel further depicts an individual colour within the image. In this, there can be varying levels of colour depths per pixel, as this criterion is entirely based on the file header which tells about the number of bits per pixel. The images stored is often uncompressed when they are 16 bpp and 32bpp. It is capable of storing only 2-dimensional images( both monochrome-single colour and colourful, with numerous colour depths). A user does not require a graphics adapter to view this file. It is not a popular format these days as it takes lots of time to upload, send and download, due to its large size.

Technical description

BMP file format comes up with the option of data compression, colour profiles and alpha channels. Alpha composting results in partial or fully transparent images which are done by incorporating or mixing one image with a background. Exchanging bitmaps between devices and applications is possible due to a unique representation of colour bitmaps of distinct colour depths, defined by Microsoft. That is why it is termed as a device-independent bitmap file format(DIBs). Additionally, it has both fixed-size and variable-sized structures. This format follows structures in the order given ahead- bitmap file header(stores general information), DIB header(Contains detailed information including pixel format), Extra bitmasks(Define pixel format), colour table( define colours used), Gap 1(Structure alignment), a Pixel array(Actual values of a pixel), Gap 2(Structure alignment)and ICC colour profile(Colour management).
