BMPs produced by scanners and old programs take up an enormous amount of space. As JPG, the same image often weighs a tenth, with no visible difference.
Drag one or more BMP files onto the dashed area, or tap it to pick them from your device.
JPG is already selected; the options hold the settings that matter for this conversion.
Press “Convert to JPG”. When it’s done, download the files one by one or all together in a ZIP archive.
Good to know. For scanned documents with lots of text, try PNG as well: it keeps characters sharper.
Source format
BMP (Windows Bitmap)
The historic Windows format: it stores pixels almost always without any compression. It’s simple and faithful, but a Full HD image easily exceeds 6 MB. Scanners, old software and some industrial machines still produce it.
Target format
JPEG (Joint Photographic Experts Group)
The photo format par excellence. It compresses the image by discarding details the eye barely notices, so a 12-megapixel photo weighs only a few megabytes. Any device can open it, from an old phone to a photo lab’s printer.
There are rare BMP variants (for example with unusual compression) that browsers can’t read. In that case open it in Paint or another editor and save it again as a standard BMP or PNG.
No. The conversion from BMP to JPG happens entirely in your browser, using your device’s computing power. Files aren’t sent or stored anywhere: when you close the page they’re gone from memory too.
Up to 100 files at a time. There’s no fixed size limit: it depends on your device’s memory. On smartphones it’s best to work in smaller batches with heavy files such as videos.
Yes, with up-to-date Safari, Chrome, Firefox, Edge and Samsung Internet. On phones, converted files end up in the Downloads folder or the Files app.
For photos to share or post online, a quality between 75 and 85 gives light files with no visible flaws. For print or archiving go up to 90-95.
Only to open the page (and, the first time, to download the components needed for that type of file). After that the conversion keeps working even if the connection drops.
