Images taken with a professional camera or some phone cameras can be really high in size hereby taking up too much memory space. You could therefore want to reduce or compress them for better optimization or because reducing images file size will make it easy to upload them on social media sites. If you have a website/blog, too many large sized images can also be a major deterrent to the viewership rate of your website, as it slows down the page loading time. Reducing image size can therefore improve your webpage loading time as well. Moreover, they will occupy less memory space and thus good for your system speed as well.
WhatsApp is one the best messaging app which can share text, images, videos and other documents. Apart from messaging, WhatsApp can be used as an image compression tool and that too it works offline.
Images are processed in two steps by WhatsApp. When you send a new image to any of the contact or group, it will first compress them. It should be noted that the compression takes place offline and it has nothing to do with your Internet connection i.e., you can compress them even when you’re offline. The compressed image will be saved in your phone memory then and at last, WhatsApp will upload & send the new image to the recipient.
Compressed images are saved in sent folder of WhatsApp and it was hidden for other applications. For example, you can’t access it from gallery or other apps. Here we will extract the compressed image from this folder in order to get the reduced file.
WhatsApp processes these images in two steps because this will reduce the photo size which will help them upload faster, thus improving user experience.
To reduce your photo file size with WhatsApp, follow these step by step instructions –
- First of all, open WhatsApp.
- Now open any contact chat.
- Here click on attachment icon and then choose Gallery.
- After this, find and select the image whose file size you want to reduce. You can also add multiple images at once.
- Now crop or rotate the photo (If you want). Finally click send button and wait for few seconds until “retry” button appears.
Note: Before sending the image, make sure that you’re not connected to Internet. Otherwise, you may send your private image to the wrong contact by mistake.
After processing the image, WhatsApp will automatically reduce its size and save the new compressed file in sent folder. To view it, open your primary file manager (I am using File Commander) and go to “Internal Memory > WhatsApp > Media > WhatsApp Images > Sent” location.
Now find your image and use it anywhere. To make it visible for other apps, simply move it to your local photo folder. You can also compress these photos by changing your WhatsApp profile picture but that will crop your image in square shape. So just try this method only.
Obviously, your new image will have very less file size as compared to the original one but speaking frankly, there is no specific percent by which they will be reduced. It will be different for each photo. It can be as small as in KB’s or it can be as big as in MB’s. What I had observed is that, if your image size is in MB’s (for example, DSLR photos), then the file size of compressed image will be reduced to few KB’s only. Here is the example –
As you can see in above picture, the original file size is 4.8 MB (It’s a DSLR photo) and when I compress it with WhatsApp, file size is reduced to 87.8 KB only which is approximately 1/55 times. This is a very big difference.
Now lets compare the quality difference between the original and compressed image. Of course, there will be some drop in their quality or pixels but if you’ll look at macro level or from normal view, both images will look same. However, if you’ll zoom the photo, then definitely anyone can point out the little change in their quality which are normal.
For better optimization, use latest version of WhatsApp. You can update your current version from Google Play Store. If you’re facing any problem, please let me know in below comment box. Stay tuned for more interesting tutorials.
