Convert VDATA to JPG

A phone may contain .vdata files after Vaulty has hidden photos or videos, while another application may require ordinary JPG files for editing, printing, or sharing. The reliable solution is to restore the media through the application that created the files, then export or convert the recovered image.

What the VDATA format is

.vdata is not a standardized image format. It is most commonly associated with Vaulty, an Android privacy app that stores protected photos and videos, but other applications can use the same extension for unrelated proprietary data.

Vaulty files are not necessarily JPEG files with a different filename. Depending on the app version, the contents may be encrypted, obfuscated, renamed, or stored with application-specific metadata. The extension alone cannot establish whether a file contains a JPEG, another media type, or non-image data.

Identify the source application from the original phone, backup, download location, or surrounding folder. File-identification tools such as TrID or the Unix file command can provide clues, but they cannot normally decode encrypted or proprietary VDATA files.

What JPG is

JPG, also called JPEG, is a widely supported raster-image format used by phones, browsers, photo editors, office software, and printers. Its lossy compression creates relatively small files, but can remove fine detail and add blocking or ringing artifacts.

JPG is appropriate for photographs and other continuous-tone images. PNG is usually preferable for screenshots containing text, diagrams, line art, transparency, or images that will be edited repeatedly.

How to recover and convert VDATA files

Restore the media in Vaulty

1. Install or open the same Vaulty application, preferably on the original Android device or a device containing the relevant app data.
2. Unlock Vaulty with the configured password or authentication method.
3. Use the app's restore, unhide, export, or share function to return each photo to the gallery or another ordinary storage location. Menu names differ between Vaulty versions.
4. Confirm that the restored file opens as an image and record its actual extension, such as .jpg, .jpeg, or .png.

Keep an untouched copy of the VDATA files and any app backup before attempting recovery. If Vaulty no longer runs, the password is unavailable, or the files came from an old installation, reinstalling or moving files between devices may not restore access; use an existing backup or the application's support resources rather than modifying the originals.

Convert the recovered image

If Vaulty exports a PNG, TIFF, BMP, or another ordinary image format, convert that exported file with desktop software such as IrfanView on Windows, Preview on macOS, or ImageMagick on Windows, macOS, and Linux:

magick exported.png -quality 90 converted.jpg

In a graphical application, open the recovered image and choose File → Export or File → Save as, select JPEG, set the quality, and preserve the original pixel dimensions.

When direct conversion is not possible

Do not rename filename.vdata to filename.jpg as a normal conversion step. Renaming changes only the filename; it does not decrypt, decode, or remove application metadata. A copy of an old, unencrypted VDATA file might happen to contain a JPEG and open after a rename, but this is version-dependent and is not a dependable recovery method.

Do not edit the file in a hex editor unless the application's documented format and recovery procedure specifically require it. Removing bytes guessed to be metadata can corrupt encryption headers or make recovery impossible.

CloudConvert and Zamzar may convert the exported PNG, TIFF, or BMP, but they generally cannot interpret arbitrary or Vaulty-specific VDATA files. Upload private media only to a service that explicitly supports the identified input format and only when cloud processing is acceptable; for Vaulty content, local conversion is safer.

Quality and compatibility limits

If the VDATA file contains encrypted media, application records, measurements, or video rather than a decodable still image, there may be no meaningful JPG conversion. Exporting a video frame or a displayed chart produces a new picture of that content, not a JPG version of the original data.

JPEG conversion is lossy. A quality setting of 85–95 is generally suitable for sharing photographs; retain the original restored file or a lossless export for archiving and avoid repeatedly opening and resaving the JPEG. Screen captures can lose pixels, hidden content, and image metadata, so use the application's export function whenever available.
