BMP is an old Windows bitmap format that almost nothing on the web or on iOS wants to deal with. Filemorph converts it to a standard JPG on your iPhone, no upload needed.
BMP files show up from old Windows software, legacy business tools and the occasional email attachment from a machine that has not been updated in years. They store every pixel uncompressed, which means large file sizes and a format most modern apps, upload forms and messaging tools do not expect.
Filemorph decodes the BMP with ImageIO and re-encodes it as a JPG, shrinking the file substantially while producing something that opens everywhere — Photos, Messages, email, any website.
In the app: Convert → To JPEG.
JPG is universally supported and far smaller than an uncompressed BMP of the same image, which makes it the practical choice whenever a BMP needs to be shared, uploaded or viewed on a phone rather than archived on an old PC.
Yes. Unlike web converters that upload your files to a server, Filemorph converts every file locally using Apple's frameworks. Nothing leaves your device, and it works with no internet connection. This conversion is in the free tier.
BMP typically stores every pixel with little or no compression, so a BMP can be several times the size of a JPG showing the same image.
iOS can preview some BMP files, but many apps and upload forms do not accept them. Converting to JPG avoids that friction.
