Frequently asked questions
Is this JXL to BMP converter really free?+
Yes. There's no file limit, no watermark, and no account required. Because the conversion runs in your browser instead of on a server, there's no processing queue to pay for.
Is my file uploaded anywhere?+
No. Orbfile decodes and re-encodes the image locally using ImageMagick compiled to WebAssembly, running entirely inside your browser tab. The bytes never leave your device.
Will converting to BMP lose quality?+
There's a quality slider so you can balance file size against visual quality. At high quality settings the difference is usually invisible.
Can I convert more than one file at once?+
Yes — drop as many files as you like and download them individually or as a single ZIP.
Is there a maximum file size?+
There's no fixed upload limit — Orbfile isn't uploading anything. The practical ceiling is your device's own memory, which comfortably handles even large, high-resolution photos.
How do I convert JXL to BMP?+
Drop your JXL file into the box above — it's automatically converted to BMP and a download link appears in seconds. No settings are required, though you can adjust quality if the tool offers a slider.
About JXL and BMP
What is JXL?
JPEG XL is a modern successor to JPEG, aiming for both better compression and lossless re-encoding of existing JPEGs.
Full JXL format guide →What is BMP?
BMP is an old Windows bitmap format that stores pixel data with little or no compression — simple, but large.
Full BMP format guide →JXL and BMP solve different problems. JXL is great for early adopters optimizing storage or bandwidth, but BMP pulls ahead when you need dead-simple, well-documented structure. If that's the situation you're in, converting is worth it.
How it works
- 1
Drop your file in
Drag your image onto the box above, or click it to browse — there's no account to create and no upload to wait on.
- 2
Pick your settings
The output format is already set for this page — just adjust any extra options shown, if there are any.
- 3
Download the result
Your browser processes everything locally and hands you a download link the moment it's done — nothing was ever sent to a server.
Is it private?
Everything happens locally, inside this browser tab. Your image is read from disk, processed with WebAssembly running on your own device, and handed back to you as a download — it's never transmitted anywhere, so there's nothing to intercept and nothing stored on a server.
Common use cases
- Legacy Windows software
- Situations that specifically require uncompressed pixel data
- Preparing images for a website or online store
- Attaching a photo to an email with a size limit

About JXL files+
JPEG XL is a modern successor to JPEG, aiming for both better compression and lossless re-encoding of existing JPEGs.
JPEG XL was designed by the same standards body behind the original JPEG, with a specific, unusual goal: not just better compression for new images, but the ability to losslessly repackage an existing JPEG into a smaller JPEG XL file and convert it back byte-for-byte later if needed. On top of that transitional trick, it also supports much better compression for new content, wide color and HDR, and both lossy and lossless modes in one format — though as a newer standard, browser and software support is still catching up.
How to open a JXL file
Opens readily in Support is limited and growing — check your browser's current compatibility. For real editing, use GIMP (with recent builds), libjxl-based tools.
Support is still rolling out; converting to JPG or PNG remains the safest bet for now if you need broad compatibility.
Good for
- strong compression at both lossy and lossless settings
- designed to succeed JPEG without starting from scratch
Watch out for
- still gaining browser and software support
About BMP files+
BMP is an old Windows bitmap format that stores pixel data with little or no compression — simple, but large.
BMP dates back to the earliest versions of Microsoft Windows, where it was used as the native format for storing raw pixel grids with minimal processing overhead — appropriate for the modest CPUs of the era, but wasteful by modern standards. Because it stores pixels close to as-is, a BMP file opens instantly and never introduces compression artifacts, but it can be five to ten times larger than a JPEG of the same image. Today it mostly survives in legacy Windows software and a few specialized pipelines that specifically want uncompressed pixel data.
How to open a BMP file
Opens readily in Windows Photos, macOS Preview, Any web browser. For real editing, use Photoshop, GIMP, MS Paint.
Good for
- dead-simple, well-documented structure
- no compression artifacts
Watch out for
- huge file sizes compared to almost any modern format
