Convert your images in 4 simple steps
Click 'Choose Files' or drag and drop your images into the upload area. Supports JPEG, PNG, WebP, GIF, TIFF, AVIF, SVG, HEIC and more.
Choose the output format from the dropdown. Set quality and other options from the Settings panel.
Hit Convert All to batch-process all files at once. Up to 3 files convert in parallel so large queues finish fast.
Download files individually or grab them all as a ZIP. Everything runs in your browser — no uploads to any server.
Convert BMP images to PNG for a much smaller lossless format with transparency support and universal compatibility. PNG compresses the same pixel data as BMP into 50–70% smaller files while remaining perfectly lossless — no quality is lost. The result is universally supported by every browser, app, and operating system.

Yes. PNG uses lossless compression. Every pixel from your BMP is stored exactly in the PNG output with no quality loss. This makes BMP to PNG the safest conversion — you get a smaller file without sacrificing any image data.
For photographs and complex images, typically 50–70% smaller. A 20 MB BMP photo might become 5–10 MB as PNG. For graphics with large areas of flat colour, PNG may be even smaller due to run-length encoding efficiency.
If the BMP contains transparency (32-bit BMP with alpha channel), it will be preserved in the PNG output. Standard 24-bit BMP without alpha channel will convert to an opaque PNG.
Choose PNG for lossless output with no quality trade-off, when the image will be edited further, or when transparency matters. Choose JPEG for even smaller file sizes (5–10× smaller than PNG) for photographs where you do not need to edit further and transparency is not needed.
Yes, and this is a very common use case. BMP screenshots are large; PNG gives you lossless compression at 50–70% smaller sizes. PNG is the standard format for screenshots in most modern operating systems.
