BMP to JPG Conversion FAQs

Answers to the most common questions about converting BMP bitmaps to JPEG

How do I convert BMP to JPG for free?

Drop your .bmp files in the box at the top, keep JPG as the output and press Convert All. It costs nothing, needs no account and adds no watermark. One file downloads as a JPG; two or more can come as one ZIP.

Can I convert BMP to JPG without losing quality?

Not perfectly, since JPG always drops a little detail, but the change is hard to spot at high settings. Raise Quality from 90 to 100 for the closest match; in our test that still cut a 47.25 MB BMP down to 4.63 MB. For an exact copy, choose PNG instead.

How much smaller is a JPG than a BMP?

Usually far smaller, because a BMP keeps every pixel with no compression. A 47.25 MB BMP photo of 5376 by 3072 pixels became 1.43 MB at quality 90 and about 597 KB at quality 75. A 3.09 MB BMP drawing became a JPG of about 96 KB. Each tile shows its own result.

What is the difference between JPG and BMP?

BMP saves every pixel as it is, so nothing is lost but files are huge. JPG compresses the picture, which removes a little detail you rarely notice and makes the file many times smaller. JPG is also the format most phones, websites and upload forms expect.

Can I convert multiple BMP files to JPG at once?

Yes. Select or drop as many BMP files as you like, each up to 100 MB, and press Convert All. They convert one after another with the same settings. Once two or more are done, Download All packs them into pixconvert-batch.zip. Very large batches depend on your device's memory.

What happens to a 32-bit BMP with transparency?

Most BMP files have no transparency, so nothing changes. If yours is a 32-bit BMP with an alpha channel, its clear areas turn white in the JPG, and the Background color picker isn't offered for BMP files yet. Pick PNG in the format menu to keep those areas clear.

Is there a size limit for BMP files?

Each BMP can be up to 100 MB, and bigger files are turned away with a message. That covers a 5376 by 3072 photo, which is about 47 MB as a BMP. If a huge file stops with a memory message, close other tabs and try it again on its own.

How do I change a BMP image to JPG without installing anything?

Open this page in your web browser, add the BMP and press Convert All. There's no app to set up, and the JPG keeps the BMP's file name with a .jpg ending. The image engine downloads once, about 14 MB, on your first conversion, then your browser keeps it.

Does the JPG keep the same size in pixels as my BMP?

Yes. The JPG has the same width and height as the BMP unless you turn on Resize. Enter a width or height in pixels there, for example to make a big scan fit a web form, and every file in the batch is scaled as it saves.

Are my BMP files sent to a server?

No. We keep basic usage stats, such as how long the editor was open, but never file names or image contents. The BMP itself is read and turned into a JPG by a worker inside this browser tab, so the picture stays on your device.
