Convert BMP Images to PNG
BMP is one of those formats that still appears in old exports and archives — but it’s not a great “working format” for the modern web.
This tool converts BMP → PNG so you can upload, reuse, and edit the image anywhere without losing quality.
Why Convert BMP to PNG?
PNG is the go-to format for clean edges and lossless graphics.
Use BMP → PNG when your image is:
- a screenshot with text
- a diagram or UI capture
- a logo or flat illustration
- anything where crisp edges matter more than tiny file size
If your BMP is a photo, WebP or JPEG might shrink it more. For text and sharp lines, PNG usually wins.
BMP vs PNG in One Minute
BMP is basically “raw-ish” storage: big files, fewer guarantees in modern upload flows.
PNG is designed for practical workflows:
- Lossless compression (no extra artifacts)
- Predictable compatibility across platforms
- Better for sharp content (text, lines, UI)
It’s often the simplest way to make an old bitmap usable again.
Common Use Cases
-
Old assets and archives Convert legacy BMP folders into something you can use everywhere.
-
CMS and platform uploads Many upload flows accept PNG but reject BMP.
-
Design and editing workflows Move BMP images into tools that expect modern formats.
-
Documentation and technical images PNG is easier to share and embed, with predictable support.
-
Batch cleanup Convert multiple BMP files at once and download as a single ZIP.
How to Use the Converter
-
Add BMP images Drag & drop or select one or multiple
.bmpfiles. -
Convert to PNG The output format is fixed to PNG for a focused workflow.
-
Download results Save images individually or download all converted files as a ZIP.
No setup, no uploads, no unnecessary options.
Important Notes
- PNG is lossless. No extra compression artifacts are introduced.
- Some BMP files may not decode in every browser. Support varies by BMP type and browser engine.
- File size can change. PNG is often smaller than BMP, but results depend on the image content.
- Metadata is removed. EXIF and related metadata are typically stripped during conversion.
How This Tool Works
Everything runs entirely in your browser:
- BMP images are decoded using modern browser graphics APIs.
- Conversion runs inside Web Workers to keep the UI responsive.
- Multiple files are processed in parallel for faster batch conversion.
- Finished PNG images are bundled locally into a ZIP for easy download.
