Description

When downloading an image from WhatsApp and opening it in Photoshop, you may encounter an error like this:

Photoshop may have trouble opening WhatsApp images directly, possibly due to how these images are saved. It seems they're often compressed and stored in a format that's best suited for viewing on mobile devices and sharing over messaging apps.

This software fixes it.

Installation

Windows:

Installer (The installer will add Wazzapp to the context menu)

Portable

Usage

Context menu

Right click inside/on a folder, or select multiple files.

Console

Wazzapp im1.jpg [im2.jpeg ...]
or
Wazzapp directory

Notes

• The only difference between the executables is that one displays the messages via tkinter messagebox, while the other does so via the console.
• The JPEG files are overwritten by the software with the fixed versions. It creates a backup in the same directory as the original image, using the extension '.bak', and deletes it once the new file is successfully saved.
• The only affected files are JPEG/JPG images, other files/directories will be skipped.
• The identification of the JPEG format relies on the imhdr library, which can sometimes overlook JPEG formats. I didn't experience any issues with it on WhatsApp images. If you're facing false negatives with WhatsApp images, feel free to open an issue, and I'll look into changing it.
