Scanner output
Some scanners and scanning software save BMP by default. JPG makes scanned photos easy to store and send.

Better qualityBMP to JPG
Smaller file sizesThis BMP to JPG converter turns bulky Windows bitmap files into compact JPGs you can email, upload and share. BMP files are usually stored with little or no compression, so a single image can take tens of megabytes. As a JPG, the same picture often needs only a small fraction of that.
It runs in your browser, free, with no sign-up and no watermark. For screenshots, diagrams and anything with sharp text, a lossless PNG is often the better target; change the To menu to PNG. Other everyday conversions include PNG to JPG and WebP to JPG.
How to use BMP to JPG Converter
-
1
Add your BMP files
Click Add Files or drop up to 10 .bmp files from a scanner, old PC folder or legacy app.
-
2
Keep JPG as the output
JPG is preselected. Choose JPEG for the .jpeg extension, or PNG for lossless graphics.
-
3
Convert and download
Press Convert and download each JPG. Compare the new sizes with the originals shown in the list.
What you can make
Old photo archives
Photo folders from older Windows PCs and cameras often hold BMPs. Convert them for today's apps and cloud storage.
Email attachments
A few BMPs can blow through attachment limits. JPGs of the same photos fit easily.
Web and form uploads
Most websites and forms do not accept BMP. JPG is accepted almost everywhere.
Legacy software exports
Industrial, medical imaging viewers and older design apps sometimes export BMP only. Convert for sharing.
Free up disk space
Converting a large folder of bitmap photos to JPG can save gigabytes.
Why BMP files are so big, and why JPG fixes it
BMP (bitmap) is one of the oldest Windows image formats. In its usual form it stores every pixel's colour directly, with no compression. A 12 megapixel photo therefore takes around 36 MB as a 24-bit BMP, no matter what is in the picture.
JPG compresses photos by discarding detail the eye barely notices. The same photo as a high-quality JPG is typically a few megabytes, often ten to twenty times smaller than the BMP. The converter writes JPG at a quality of about 90, which looks the same as the bitmap at normal viewing size.
BMP is still around because it is simple: scanners, industrial cameras, embedded devices and older software can write it without a compression library. That simplicity is the only real advantage. For storing, sharing or publishing images, JPG (for photos) or PNG (for graphics) is better in every way. If you then need a web-optimised version, JPG to WebP or JPG to AVIF goes further.
JPG or PNG for your BMP?
Pick the output by what the image shows:
- Photos and scanned pictures: JPG. Huge size savings, no visible loss.
- Screenshots, UI captures, diagrams, charts and text: PNG. It is lossless, keeps text razor sharp and still compresses these images far below BMP size. Switch the To menu to PNG before converting.
- Pixel art and images you will keep editing: PNG, so repeated saves do not degrade them.
Two more details. Some BMPs are 32-bit with an alpha channel; JPG cannot store transparency, so those areas become white, while PNG keeps them. And the converter keeps the exact pixel dimensions: if your scans are larger than you need, shrink them afterwards with Resize Image, or straighten them with Rotate Image. For faded old photos, the paid AI Photo Restoration tool can repair scratches and colour.
Converting BMP files without installing anything
On Windows you can open a single BMP in Paint and choose Save as JPEG. That works, but it is slow for a folder of files, and Paint gives you no idea how big the result will be. On Mac, iPhone and Android, BMP support is patchier, and many apps will not open the files at all.
This page handles BMP files in any modern browser on any system, 10 at a time. It shows the original size of each file, and after converting you can compare it with the JPG. There is nothing to install and no account.
- Large archives: work through them in batches of 10. Reload the page between batches.
- Scans of documents: if the goal is readable text, try PNG output, or extract the text directly with AI Image to Text.
- Old family photos: convert to JPG first so they are easy to back up and share, then consider restoration for damaged ones.
- Keep the BMPs until you have checked the JPGs, especially for scans you cannot easily redo.
Frequently Asked Questions
Still stuck? Contact us.
How do I convert BMP to JPG?
Add your BMP files, keep JPG as the output and press Convert. Download each JPG with its button.
Is the BMP to JPG converter free?
Yes. No sign-up, no watermark and no daily limit. Up to 10 files per batch.
How much smaller will the JPG be?
Usually ten to twenty times smaller for photos, because most BMPs are uncompressed.
Does converting BMP to JPG lose quality?
Slightly, since JPG is lossy, but at the high quality setting used here photos look the same. For text and diagrams, choose PNG to avoid any loss.
Is BMP to JPEG the same thing?
Yes. JPG and JPEG are the same format. Pick JPEG in the To menu if you need the .jpeg extension.
Are my BMP files uploaded?
No. BMP to JPG conversion runs in your browser, so the files stay on your device.
What happens to transparency in 32-bit BMPs?
JPG cannot store it, so transparent areas are filled with white. Convert to PNG to keep transparency.
Is there a size limit for BMP files?
There is no fixed limit because your browser does the work, but very large bitmaps can be slow on phones or older computers.
Why are BMP files so large?
Most BMPs store each pixel without compression, so size depends only on resolution, not on content.
Can I convert JPG back to BMP?
Yes, the Image Converter can output BMP. There is rarely a reason to, unless an old program requires it.
Should I use JPG or PNG?
JPG for photos and scans of pictures. PNG for screenshots, diagrams, text and anything you will keep editing.
Does it work on Mac?
Yes. The converter runs in Safari, Chrome and Firefox on macOS, as well as on Windows, Linux and phones.
What kinds of BMP files are supported?
Any BMP your browser can open, which covers the common 24-bit and 32-bit Windows bitmaps from scanners, cameras and older software.
