What this tool does

Source pixels (or vector paths) are rasterized as required, then encoded to PNG.

ICC profiles may be copied, transformed, or stripped depending on encoder defaults.

  • BMP family — Raster stores pixels per subsampling and compression scheme chosen at encode time.
  • PNG family — PNG output: lossless DEFLATE; full alpha and grayscale modes.
  • Encode traits — Raster exports fix dimensions, subsampling, and ICC embedding per encoder—vectors rasterize to one pixel grid.

How to convert BMP to PNG?

  1. Choose file — upload a BMP file that matches this page (allowed extensions apply).
  2. Convert to PNG — lock the target format if needed, then start the job and wait for status updates.
  3. Download — grab the finished file from your job link before the retention window ends.

Why convert BMP to PNG?

Each hop trades smaller files against visible defects; switching formats can trade alpha, animation, or HDR side data against simpler decode surfaces.

Prefer PNG when alpha, animation, HDR sidecars, or ICC handling matter more than the smallest on-disk result.

Vectors versus rasters trade infinite zoom against predictable pixel weight—prefer PNG when bitmap semantics matter more than editable paths.

Common reasons to convert BMP to PNG

  • Sync PNG into DSM when Sketch stayed BMP but the style guide expects PNG.
  • Emit PNG from GitLab CI before Slack when reviewers diff BMP screenshots.
  • Serve PNG from next/image when builds optimize assets but archives stay BMP.
  • Stage PNG on Marketing Cloud when ZIP packs must match hosted filenames.
  • Point Imgix URLs at PNG when CDNs rewrite BMP masters already in S3 buckets.

Will converting BMP to PNG affect quality or file size?

Pixels decoded from the source usually remain visible after conversion.

Another lossy step softens edges; JPEG detail lost earlier never returns—size exports to the screen or print size you need.

BMP vs PNG

BMP (BMP)

BMP is a simple Windows bitmap that is often uncompressed, so files balloon quickly. You still see it from legacy apps, scanners, or embedded devices that dump raw pixels. PNG or JPEG is usually easier to share online.

PNG (PNG)

PNG compresses bitmaps without throwing pixels away and supports smooth transparency. UI shots, logos, and crisp diagrams often ship as PNG. Photo-sized PNGs are usually heavier than JPEG because nothing is discarded.

BMP to PNG changes which apps open first—Chrome, Photoshop, and Outlook each bind double-click actions to the new extension.

Troubleshooting

  • Lossy recompression: blocking, ringing, and banding show first on text, edges, and skies—inspect at 100% zoom.
  • Alpha: formats without an alpha channel (JPEG, most HEIC stills) cannot produce real transparency in the output unless you supply it elsewhere.
  • Dimensions and DPI: raster outputs fixed pixel grids—upscaling later softens detail; embedded ICC profiles may shift colors across viewers.
  • Decode support: older viewers may lack PNG decoders (AVIF, WebP); verify the destination stack.
  • Upload fails or stalls: refresh the page, try a different browser, or disable strict content blockers for this session.

BMP to PNG FAQ

Most still images finish quickly, but huge TIFF masters or multi-megapixel raw exports can queue longer. HEIC and AVIF decoding also adds work compared with small JPEGs.

Yes. Upload a file, confirm the output format, run the job, and download the result from the status page.

Use the From/To menus on this converter or open another slug page if the pair you need is supported. Unsupported combinations will not appear as selectable options.

PNG, WebP (depending on mode), GIF, and SVG workflows handle alpha differently than JPEG. If your BMP artwork relied on transparency, pick PNG accordingly or expect a flat background. Preview edges after conversion.

PNG opens in virtually every image viewer when PNG is JPEG or PNG. AVIF and WebP need newer browsers or apps. If the recipient runs older software, choose a more conservative format after checking their environment.
