Add the BMP
Drop, paste, or choose the bitmap that needs a more broadly compatible PNG handoff. It stays on your device.
Free BMP to PNG converter
Convert BMP to alossless PNG image.
Fileverses converts a BMP to PNG in your browser when a site, editor, or recipient accepts PNG more readily than a Windows bitmap. PNG losslessly writes the browser-decoded pixels and can retain decoded alpha, but it does not restore earlier detail, remove a background, or promise a smaller download.

About this converter
Free BMP to PNG conversion, built for a real workflow.
BMP is a simple raster bitmap often used in Windows-oriented or older workflows, while PNG is a broadly supported raster format with lossless compression and alpha support. This route decodes the BMP in your browser and uses the canvas PNG encoder to write the rendered pixels without a lossy quality setting. That can make an image easier to use in web, document, and modern-editor workflows, but conversion is not a recovery process: it cannot recreate detail lost before the BMP was made, remove an opaque background, or guarantee identical color handling in every application. PNG may be smaller or larger depending on the bitmap's dimensions and pixel content, so compare the actual download when size matters.
- The browser creates a PNG from decoded BMP pixels without a lossy quality setting; it is not a byte-for-byte copy of the original bitmap container.
- PNG can carry alpha, but an opaque BMP remains opaque. The converter does not identify, erase, or create a transparent background.
- PNG is useful for web, documents, and editors that accept it more readily than BMP; keep BMP when a legacy application explicitly requires a Windows bitmap.
- File size depends on dimensions and image content. Lossless PNG output can be smaller or larger than the BMP, so check the finished file for upload limits.
How it works
Upload once.
Export PNG.
Keep PNG selected
PNG is preselected for a lossless rendered-pixel export, not for background removal or detail recovery.
Convert and compare
Download the PNG, then check its visible result, alpha behavior, and file size in the site, editor, or recipient workflow before replacing the BMP.
Made for real pipelines
BMP to PNG.
One workspace.
Convert without uploading your assets. Switch outputs anytime — web, print, icons, and document targets from the same batch.
Convert BMP to PNGLossless PNG pixels
Write the browser-decoded bitmap pixels to PNG without JPEG- or WEBP-style quality loss.
Honest alpha behavior
PNG can carry existing decoded alpha, but the converter does not remove backgrounds or make opaque artwork transparent.
Browser-local compatibility
Create a PNG on your device, then validate final size and appearance in the receiving workflow.
Good to know
Questions, answered.
Why convert a BMP to PNG?+−
Convert when a website, document, editor, or recipient accepts PNG more readily than BMP. PNG is widely used for general raster-image compatibility, while BMP remains useful for a workflow that explicitly requires a Windows bitmap.
Is BMP to PNG conversion lossless?+−
The browser's PNG encoder losslessly stores the pixels it decoded from the BMP. It cannot restore image detail, metadata, color handling, or editing history that was absent or lost before conversion.
Will BMP to PNG remove or create a transparent background?+−
No. PNG supports alpha, but this converter only writes the decoded image pixels. An opaque BMP remains opaque; the tool does not detect, erase, or replace a background.
Will the PNG always be smaller than the BMP?+−
No. BMP is often uncompressed, but PNG size still depends on dimensions and pixel content. Compare the downloaded PNG when a storage, upload, or delivery limit matters.
Where can I use a BMP converted to PNG?+−
Use the PNG in web pages, documents, editors, or receiving systems that explicitly support PNG. Check the target's file-size and image rules because conversion does not configure an external service.
Does Fileverses upload BMP files to convert them to PNG?+−
No. Fileverses performs this BMP-to-PNG conversion in your browser, so the source bitmap is not sent to a conversion server.
