Why Convert BMP to JPG?
BMP to JPG conversion turns a bitmap (BMP) image into a compact JPG file. BMP files are usually uncompressed, so they are very large. A JPG of the same picture is typically a small fraction of the size and opens on almost every device, app and website, which makes it easy to email, upload and share.
BMP (bitmap) is one of the oldest image formats on Windows.
It stores a picture pixel by pixel, usually with no compression at all, so even a modest image can take up several megabytes.
That was fine in the past, but today it causes problems:
- The file is too big to email or upload.
- A web form, portal or marketplace says "JPG or PNG only".
- Web pages, phones and many apps don't handle BMP well, or at all.
- A folder of old BMP files eats up storage and backup space.
- Cloud tools and messaging apps reject or slow down on large bitmaps.
JPG fixes these, because it is compact and the most widely supported image format in the world.
BMP vs JPG at a glance:
| BMP | JPG | |
|---|---|---|
| Typical file size | Very large (usually uncompressed) | Much smaller |
| Compression | Usually none | Lossy |
| Compatibility | Windows and legacy software, limited on the web | Almost every device, browser and app |
| Transparency | Rarely supported | Not supported |
| Best for | Legacy software, raw pixel data | Photos, sharing, email, web uploads |
Good to know:
- JPG is not always the best choice. For screenshots, logos, text and flat-colour graphics, JPG compression can soften edges. PNG is usually better for those: it is lossless and typically much smaller than BMP too. For photos and photo-like images, JPG is ideal.
- Keep the original if it matters. JPG is lossy. If the BMP is an important master, keep a copy.
- Transparency is replaced by a colour. JPG can't store transparency, so any transparent areas are filled with the background colour you pick in Settings (white is the usual choice).

Frequently Asked Questions
How do I convert BMP to JPG?
Open Teasoft's BMP to JPG converter, add your BMP files, choose the quality and background colour, click Convert to JPG and download the results as individual files or a ZIP.
What is a BMP file?
BMP (bitmap) is an image format from Windows that stores pictures pixel by pixel, usually without compression. That keeps every pixel exactly as is but makes files very large.
Why are BMP files so big?
Most BMP files are uncompressed, so every pixel is stored in full. JPG compresses the image, so the same picture takes up far less space.
How much smaller will my JPG be?
Usually much smaller, often a small fraction of the BMP's size for photos. The exact saving depends on the image and the quality setting.
Does converting BMP to JPG reduce quality?
Slightly, because JPG is a lossy format. At 85–92% quality the difference is usually not visible for photos. Screenshots and text can look softer, so PNG is a better choice for those.
Should I convert BMP to JPG or PNG?
Choose JPG for photos and the smallest files. Choose PNG for screenshots, logos, icons and text, where sharp edges matter.
Does BMP to JPG keep transparency?
No. JPG does not support transparency, so any transparent areas are filled with the background colour you choose in Settings.
Can I convert many BMP files at once?
Yes. Add up to 50 BMP files in one batch, each up to 100 MB, and download them all as a ZIP.
Why won't my BMP file upload to a website?
Many websites and forms don't accept BMP, or limit file size. Converting to JPG makes the file smaller and compatible.
Are my files uploaded to a server?
No. Conversion happens in your browser, and your files are never uploaded.
Can I convert BMP to JPG on my phone?
Yes. The converter works in the browser on Android, iPhone, tablets and computers. You do not need to install an app.
Is the BMP to JPG converter free?
