.rem extension that other phones, editors, and sharing services cannot open. The practical solution is to decrypt or export the photo from the originating device, then save the resulting image as .jpg for broader compatibility and smaller files.
What the REM format is
.rem is not a universal image format. On older BlackBerry devices, it usually identifies an encrypted copy of a photo, video, or audio file created when content protection or media-card encryption was enabled. The underlying photo may have been JPEG data, but encryption changes the file contents, so renaming an encrypted file does not convert it. Other software also uses .rem for unrelated data, so identify the originating device or application first.
BlackBerry encryption must normally be removed by the device or by software that has the required encryption credentials. If the device, encryption password, or recovery method is unavailable, a generic converter cannot recover the image.
What the JPG format is
JPG, also called JPEG, is a lossy raster format supported by web browsers, phones, photo editors, document systems, and messaging services. It usually produces much smaller files than uncompressed formats and suits photographs, but repeated JPEG saves can add blocking, ringing, and fine-detail loss. JPG does not support transparency and is unsuitable as a master format when lossless editing is required.
How to convert a BlackBerry REM file
- Make a backup of the original
.remfile and keep the BlackBerry device or storage card unchanged until the export works. - Unlock the BlackBerry that created the file. On older BlackBerry OS models, open Options → Security Options → Encryption and disable content protection or media-card encryption if the device permits it. On BlackBerry 10, the corresponding controls are under the security and privacy settings. Names and behavior differ by model and operating-system version.
- Use the device’s gallery or file manager to open and share the photo, or copy it through the appropriate legacy BlackBerry desktop software. Some devices decrypt media while it is accessed; others require an on-device export or sharing operation. BlackBerry Desktop Software generally applies to older BlackBerry OS devices, while BlackBerry Link was used with many BlackBerry 10 devices.
- Check the exported file in an image viewer. If it contains JPEG data but retains a
.remsuffix, rename a copy to.jpgand test it. Renaming is valid only after decryption; it does not remove encryption. - If the exported image is readable but in another format, open it in IrfanView, XnView MP, GIMP, or another desktop editor and choose File → Save As or File → Export, then select JPEG and set the quality. ImageMagick can write a confirmed readable input with
magick input.jpg -quality 90 output.jpg; it cannot decrypt an encrypted REM file.
How to identify a non-BlackBerry REM file
Do not force the extension to .jpg until the file type is known. On macOS or Linux, run file input.rem. On Windows, inspect a copy with a hex viewer or try it in a format-identification utility such as TrID. A JPEG normally begins with the hexadecimal signature FF D8 FF and ends with FF D9; a matching header indicates that the file may already contain JPEG data, although a complete file check is preferable.
If the file is already JPEG data, rename a copy to .jpg or open it in XnView MP or IrfanView and export it. If its signature is unknown, use the program that created it to export an image. An unrelated REM data file may not contain an image at all.
Online and desktop converter options
CloudConvert, Zamzar, and similar online services can convert a readable, supported image after its actual format has been identified. They generally cannot decrypt BlackBerry REM files, and an upload may simply fail because the service cannot recognize the extension. Use a local application such as XnView MP, IrfanView, GIMP, or ImageMagick for private photographs and for files that require decryption.
Quality and compatibility limits
Decryption does not restore detail already lost in the original photograph. Saving an existing JPEG as JPEG adds another lossy-compression generation, so retain the decrypted original and use a quality setting around 90–95% for a delivery copy when the software uses a comparable scale. Keep a lossless or original export for future editing, and use PNG instead when transparency or repeated editing matters.

Frequently asked questions
Can I convert a REM file to JPG by renaming the extension?
No, renaming a REM file does not decrypt it or make it a readable image. The encrypted media must first be decrypted with the required BlackBerry security information, then exported as JPG.
Will REM to JPG reduce image quality?
It can, because JPG uses lossy compression and may re-encode the decrypted image. The result usually keeps the source dimensions, but visible quality depends on the export quality setting and the original image.
Will transparency or other image data be lost when converting REM to JPG?
Yes, JPG cannot preserve transparency, so transparent areas are flattened against a background during export. Some metadata and other information from the decrypted source may also be discarded.
Why does my REM file fail to open or convert to JPG?
A REM file is encrypted, so ordinary image software cannot read it until it is decrypted using the security context associated with the original BlackBerry media. A damaged file or missing encryption information can prevent recovery even when the file is renamed with an image extension.
