About BMP
BMP is the device-independent bitmap format of Windows. It usually stores every pixel uncompressed.
Legacy Windows software, simple paint programs and embedded systems.
Without compression a BMP is many times larger than a PNG of the same image.
Convert BMP to JPEG online free, no account required — JPEG is the universal lossy photo format.
Change BMP to JPEG without losing quality — convert BMP to JPEG free in your browser.
Why is my BMP file so enormous compared to the same picture as PNG? The Windows bitmap stores pixels raw with no compression at all, so even a small screenshot can weigh megabytes that PNG stores in kilobytes.
About JPEG
JPEG is the standard lossy image format, named after the Joint Photographic Experts Group that published it in 1992. It shrinks photos to a fraction of their raw size by discarding fine detail.
Photos from cameras and phones, images on the web and email attachments; every device and app opens it.
JPEG has no transparency, stores 8 bits per colour channel, and loses a little more quality every time it is saved again.
Why convert photos to JPG? It is the one image format every website, app and photo service accepts, and at high quality settings the loss is invisible.
What changes when you convert BMP to JPEG
- The BMP picture is re-encoded as JPEG at the default quality settings, so it looks close to the original but is not bit-identical.
- JPEG uses lossy compression: the encoder discards the detail that is least noticeable, so the file is smaller than the BMP but cannot be turned back into the original.
Settings you can change
Before you convert BMP to JPEG, you can adjust: Width, Height, Scale fit, Crop position, Never enlarge, Quality, Lossless, Progressive, Remove metadata, Auto-orient from EXIF, Rotate, and Background.
Limits
Each plan sets a maximum file size and a number of conversions per day, and video and audio files also have a maximum length. Guests can convert files up to 100 megabytes and 5 per day; a free account raises this to 500 megabytes and 25 per day; paid plans go up to 100 gigabytes.
Your converted JPEG file is kept for 2 hours, then deleted.
BMP to JPEG: questions and answers
Does converting BMP to JPEG reduce quality?
The BMP picture is re-encoded as JPEG at the default quality settings, so it looks close to the original but is not bit-identical. JPEG uses lossy compression: the encoder discards the detail that is least noticeable, so the file is smaller than the BMP but cannot be turned back into the original.
What is the difference between BMP and JPEG?
BMP is the Windows bitmap format, usually uncompressed. JPEG is the universal lossy photo format.
Can I change the settings when converting BMP to JPEG?
Before you convert BMP to JPEG, you can adjust: Width, Height, Scale fit, Crop position, Never enlarge, Quality, Lossless, Progressive, Remove metadata, Auto-orient from EXIF, Rotate, and Background.
Do I need an account to convert BMP to JPEG?
No. You can convert BMP to JPEG without an account; signing in raises the file-size and daily limits.
How long is my converted JPEG file kept?
The JPEG file you convert from BMP is kept for 2 hours, then deleted automatically.
Will the JPEG file be smaller than my BMP?
JPEG uses lossy compression: the encoder discards the detail that is least noticeable, so the file is smaller than the BMP but cannot be turned back into the original.
Is the JPEG an exact copy of my BMP?
The BMP picture is re-encoded as JPEG at the default quality settings, so it looks close to the original but is not bit-identical.
