About this app

(This app is not related to WhatsApp or WhatsApp Inc. in any way)
WhatsApp image optimizer is a simple tool to reorganzie your images after they have been messed up WhatsApp. This means that the images are not properly sorted by the date they have been taken at.
Why does this happen?
Whenever you send an image via WhatsApp, WhatsApp removes any unnecessary metadata from the image, including the date taken. The metadate that is affected by this is called Exif-Data(see below)
The removal of this data normally does not cause any problems as the phone gallery uses the file creation date information to sort the imagesd in your gallery. So the normal use does not encounter any issues. But in case of, for example, a user restoring a WhatsApp-Backup after switching to a new device, the file creation date changes to the date the backup is restored. This will cause all WhatsApp images to be shown as taken on the same day. This is the point when this app comes to your help. Using the file name, in which WhatsApp saves the date created of the image, we will recreate the date taken and save it into the images metadata. After the optimization process is done, all your images will be sorted properly again. THIS APP WILL NOT OVERRIDE IMAGES WHICH ALREADY CONTAIN EXIF DATA.

THE CREATOR OF THIS APP DOES NOT TAKE RESPONSIBILITY FOR ANY PROBLEMS CAUSED BY THIS APP DURING THE OPTIMIZATION PROCESS.

--- What is EXIF? ---
from Wikipedia:
"Exchangeable image file format (officially Exif, according to JEIDA/JEITA/CIPA specifications) is a standard that specifies the formats for images, sound, and ancillary tags used by digital cameras
The metadata tags defined in the Exif standard cover a broad spectrum:

- Date and time information. Digital cameras will record the current date and time and save this in the metadata.
- Camera settings. This includes static information such as the camera model and make, and information that varies with each image such as orientation (rotation), aperture, shutter speed, focal length, metering mode, and ISO speed information.
- A thumbnail for previewing the picture on the camera's LCD screen, in file managers, or in photo manipulation software.
- Descriptions
- Copyright information."

Ratings and reviews

Great App, does what it sets to do! I would like it to also check the Private and Images Sent folder, as now only does the Images folder. I would like to maybe have a review screen or maybe have the results written afterwards for double checking. I noticed that some photos that are around midnight get the date wrong by one day. Minor issue, since Whatsapp images could have been received a different day from when it was taken. I would also like to see this app for Whatsapp videos.

Great. It fixes the mess whatsapp unable to do after restoring its backups. RAR can do, this app can do. Yet whatsapp still ignoring file modification dates. Thank you so much for fixing dates. I thought where is no other way then to archive files and overwrite WA files. Also I was able to fix dates for images damaged on previous restores.

This helped me correctly reorder around 2000 pictures after whatsapp failed to transfer them in the correct order. It did so quickly, and with no fuss. It amazes me that this is necessary, but I'm very happy this exists.
