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.
Convert JPEG to BMP online free, no account required — BMP is the Windows bitmap format, usually uncompressed.
Change JPEG to BMP without losing quality — convert JPEG to BMP free in your browser.
Why does my photo get worse every time I edit and save it as JPG? Each save re-compresses the image and piles new artifacts on the old ones — working from a lossless original and exporting once to JPG avoids the buildup.
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.
Why convert an image to BMP? Rarely on purpose: only legacy Windows software and some industrial tools expect uncompressed bitmaps.
What changes when you convert JPEG to BMP
- The JPEG picture is re-encoded as BMP at the default quality settings, so it looks close to the original but is not bit-identical.
- JPEG is a lossy format and BMP is not: the BMP keeps the decoded JPEG exactly, but it cannot restore detail the JPEG compression already removed, and the file is usually larger.
Settings you can change
Before you convert JPEG to BMP, 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 BMP file is kept for 2 hours, then deleted.
JPEG to BMP: questions and answers
Does converting JPEG to BMP reduce quality?
The JPEG picture is re-encoded as BMP at the default quality settings, so it looks close to the original but is not bit-identical. JPEG is a lossy format and BMP is not: the BMP keeps the decoded JPEG exactly, but it cannot restore detail the JPEG compression already removed, and the file is usually larger.
What is the difference between JPEG and BMP?
JPEG is the universal lossy photo format. BMP is the Windows bitmap format, usually uncompressed.
Can I change the settings when converting JPEG to BMP?
Before you convert JPEG to BMP, 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 JPEG to BMP?
No. You can convert JPEG to BMP without an account; signing in raises the file-size and daily limits.
How long is my converted BMP file kept?
The BMP file you convert from JPEG is kept for 2 hours, then deleted automatically.
Does converting JPEG to BMP restore the quality the JPEG lost?
JPEG is a lossy format and BMP is not: the BMP keeps the decoded JPEG exactly, but it cannot restore detail the JPEG compression already removed, and the file is usually larger.
Is the BMP an exact copy of my JPEG?
The JPEG picture is re-encoded as BMP at the default quality settings, so it looks close to the original but is not bit-identical.
