How to Convert BMP to PNG

Why Convert BMP to PNG?
Private by design
BMP → PNG runs in your browser. Files are not uploaded to a remote conversion queue.
Ready for the next step
Convert when a site, editor, or teammate expects PNG instead of BMP.
Preserve detail
PNG: Lossless DEFLATE (PNG). Typically lossless or lightly transformed for editing and archival use.
Transparency aware
PNG can keep transparent pixels when the source supports them.
BMP vs PNG
A quick side-by-side before you convert — deeper comparison lives on the full guide.
| Feature | BMP | PNG |
|---|---|---|
| Kind | raster image | lossless raster image |
| Compression | varies | Lossless DEFLATE (PNG) |
| Lossy / lossless | Lossless / not lossy | Lossless / not lossy |
| Transparency | Not supported / N/A | Supported |
| Best for | Legacy Windows assets; Simple pixel-perfect game or UI sprites from old toolchains | Screenshots; Logos and icons |
| Typical size | Very large — megabytes even for modest resolutions | Larger than JPG for photos; excellent for graphics with flat color |
| Browser / web support | Technically displayable in some browsers but never preferred — convert first | All modern browsers |
| Compatibility | Opens everywhere on Windows desktops and in most desktop editors; convert before web or mobile sharing because files are huge | Universal across browsers, phones, and design tools — the safest lossless web raster alongside JPG for photos |

What happens to image quality?
PNG compatibility: Universal across browsers, phones, and design tools — the safest lossless web raster alongside JPG for photos Lossless output — transparency and full colour depth are preserved.
Tip
Keep an original copy of your BMP file if you may need to reconvert later.
Does PNG support transparency?
PNG can store transparent pixels — PNG supports full 8-bit (and more) alpha transparency — ideal for soft edges, overlays, and logos on any background.

Frequently Asked Questions
More on quality loss: conversion quality guides · problem-solution guides
Does converting BMP to PNG reduce quality?
Often no for lossless or remux-style paths. Quality drops when you re-encode with lossy settings, downscale, or flatten features like transparency.
Can you recover quality after converting?
Not from a lossy output alone. Return to the original master (or a better source). Converting to a lossless format does not resurrect discarded detail.
Where can I learn more about conversion quality?
Browse Format Convertly’s Quality guides for topics like whether conversion reduces quality, JPG↔PNG myths, WebP/MP3/MP4 tradeoffs, recovery limits, and generational loss — each links to the right converter.
Why is my BMP file so huge?
BMP is usually uncompressed. Convert BMP to PNG for screenshots/UI or JPG for photos — file size drops sharply while quality stays practical for sharing. Full guide: Why Is My BMP File So Huge?.
Where can I find more problem-solution guides?
Browse the Guides hub for long-tail fixes — HEIC won’t open, PNG too large, PDF not searchable, video too large, WebP upload failures, and more — each links to the right converter or tool.
What is a BMP file?
BMP is an uncompressed (or lightly packed) Windows bitmap raster image. BMP is a simple pixel grid historically tied to Windows Paint and older games. Files are easy to decode but enormous compared with PNG or JPG, so convert BMP when you need to share, archive, or publish the image.
Is BMP lossy or lossless?
BMP is typically lossless or non-destructive in common use (varies).
What is a PNG file?
PNG is a lossless raster image format with full alpha transparency. PNG keeps every pixel intact and supports translucent edges — ideal for screenshots, UI, and logos. Photos are safer as JPG/WebP/AVIF when you care about download size.
