How do I convert BMP to JPG?

Add your BMP file to the upload area above, then press Convert. The JPG file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to JPG reduce quality?

JPG uses lossy compression, so some data is discarded. At the default quality the difference is very hard to see or hear; raise the quality setting if you need to be certain, at the cost of a larger file.

How large a file can I convert?

Up to 120 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

BMP and JPG explained

BMP stores pixels essentially raw, with little or no compression. A 1920×1080 BMP is around 6 MB regardless of what the picture contains, because every pixel takes the same space whether it is part of a gradient or a flat colour.

JPEG is a lossy image format designed for photographs. It works by discarding detail the human eye is least likely to notice, particularly in colour and in smooth gradients, which is why it compresses photos far better than it compresses text or line art.

Where BMP files come from: Legacy Windows software, some scientific and industrial imaging tools.
Where JPG is used: Digital cameras, phone screenshots on Android, and essentially every photo on the pre-2015 web.

BMP vs JPG

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

BMP compared with JPG
Property	Source	Target
Compression	Uncompressed	Lossy
Transparency	No	No
Animation	No	No
Introduced	1990	1992
Browser support	Broad, though rarely the best choice today.	Opens everywhere — every browser, OS and device.

BMP is stronger at: Trivially simple to read and write. No compression artefacts whatsoever. Still readable by very old software.
JPG is stronger at: Opens on literally every device, browser and application ever made. Small files for photographic content. Adjustable quality, so you control the size/fidelity trade-off.

Why convert BMP to JPG?

People make this switch when they run into the limits of BMP: almost always — PNG gives you the same lossless fidelity in a fraction of the space. JPG is the better fit when you are sharing a photograph and compatibility matters more than squeezing out the last few kilobytes.

There is also a size argument: BMP stores data with little or no compression, so the JPG version is normally dramatically smaller for the same content.

BMP limitations that prompt the switch: Enormous files. No standard support for transparency in most variants. Effectively unusable on the web.
What you give up: No transparency — there is no alpha channel at all. Visible artefacts around sharp edges and text.

Does converting BMP to JPG reduce quality?

BMP stores your data exactly; JPG does not. Some detail is discarded permanently in exchange for a much smaller file, which is usually the right trade for sharing and publishing. Keep your BMP original if it is the only copy — the conversion cannot be undone.

Saving a JPEG at 100% quality is still lossy — it is a large file that has been through the same discarding process, not a lossless copy.
