How to use BMP to JPG Converter

  1. 01

    Upload your BMP file

    Drag and drop or browse to a .bmp file — up to 20 MB anonymous, 50 MB with a free account, or 200 MB on a paid plan, sent over HTTPS.

  2. 02

    Set the JPG quality (optional)

    Leave it at the default 85 for a clean, small photo, or push it to 90–95 for archival prints and down to 60–75 when the smallest file matters most.

  3. 03

    Automatic BMP decoding and JPG encoding

    The uncompressed bitmap — bottom-up or top-down — is decoded and re-encoded as a JPG at your chosen quality, shrinking the file far more than a PNG conversion would.

  4. 04

    Download your JPG

    Get the file through a signed download link in seconds. It is auto-deleted from our servers within 24 hours, and the uploaded BMP within 6–24 hours.

Why choose our BMP to JPG Converter

The smallest possible output

Uncompressed BMP plus adjustable JPG compression gives you the smallest files of any BMP conversion we offer — ideal for photos.

Handles every BMP variant

Both standard bottom-up BMPs and top-down (negative-height) BMPs decode correctly, so files that failed elsewhere convert cleanly here.

Private by design

Uploads use HTTPS, converted JPGs are auto-deleted within 24 hours, and uploaded BMPs are removed within 6–24 hours.

Free to start

Anonymous visitors get 1 free server conversion up to 20 MB; free accounts get 3 conversions every 30 days at 50 MB with batches of 5.

No signup for a quick try

Convert your first BMP to JPG right away — no account needed until you want more conversions, larger files, or batch processing.

Settings guide

Quality (1–100, default 85)
Controls the JPG compression level. The default of 85 is a sweet spot for photos: visually clean with small files. Use 90–95 for prints or archiving, and 60–75 when the smallest possible file matters more than fine detail.

About the formats

BMP

BMP is the legacy Windows bitmap format, dating back to early versions of Microsoft Windows. Files are usually stored uncompressed, and they typically come from old Windows software, scanners, or system screenshots.

BMP stores pixels exactly and is trivially simple to read, but the lack of compression makes files enormous — often many times larger than an equivalent PNG. Browsers and mobile apps handle it poorly, and there is no benefit that justifies the size. Convert BMP to PNG to keep lossless quality, or to JPG for photographs where smaller files matter.

JPG

JPG (also written JPEG) is the most widely used lossy image format for photographs, standardized by the Joint Photographic Experts Group in 1992. Practically every camera, phone, and image application can create and open it.

Its strengths are small file sizes for photos and universal compatibility across devices, browsers, and software. The trade-offs: lossy compression introduces artifacts, there is no transparency support, and quality degrades a little more with every re-save. Use JPG for photographs; choose PNG for screenshots, logos, or anything that needs sharp edges or transparency.

Troubleshooting

Text and sharp edges look blocky
JPG compression creates artifacts around hard edges. Raise the quality setting toward 95, or use our BMP to PNG tool for screenshots, diagrams and images with text.
My file won't upload
Make sure the file is a genuine .bmp bitmap — renamed files from other formats are rejected. Also check the size limits: 20 MB anonymous, 50 MB free account, 200 MB paid.
The JPG is bigger than I expected
Very high quality values (95–100) keep files large. Lower the quality toward the default 85 — for most photos the visual difference is negligible while the file shrinks noticeably.

FAQ

When should I pick JPG instead of PNG?
Choose JPG for photographs and scans: it produces by far the smallest files. Since BMP is completely uncompressed, converting a photo BMP to JPG shrinks it massively.
Can I control the JPG quality?
Yes. The quality setting goes from 1 to 100 and defaults to 85, which keeps photos visually clean while staying small. Higher values mean larger files.
Are my files kept private?
Yes. Uploads travel over HTTPS, converted outputs are auto-deleted within 24 hours, and uploaded inputs are removed within 6–24 hours.
What limits apply to this tool?
Anonymous: 1 free server conversion, files up to 20 MB. Free account: 50 MB files, 3 conversions per 30 days, batches of 5. Paid: 200 MB files and batches of up to 100.
How much smaller will the JPG be than my BMP?
BMP stores every pixel uncompressed, so a JPG conversion is typically the smallest output we offer — often 90%+ smaller than the original BMP, especially for photographs.
Does this handle unusual BMP files, like top-down BMPs?
Yes. The decoder correctly supports both standard bottom-up BMP files and top-down (negative-height) BMP files, so files that failed in other tools should now convert cleanly.
Can I convert multiple BMP files to JPG in one go?
Yes. Free accounts can batch up to 5 files at once; paid accounts up to 100. Anonymous users get 1 free server conversion at a time.
