Here are 2 free bulk crop image Android apps. There exist so many image resizer Android apps (check the list) which come with a feature to crop a single image at a time, but adding multiple images and cropping them is not available in such apps. Therefore, these 2 Android apps come in handy.
Once you’ve added the images, you can select the pre-defined crop ratio or set a custom crop area or size. After that, you can process the images and use the cropped images.
There will be ads on the interface of these bulk image crop Android apps, but it won’t distract or stop you from cropping the images with ease. These apps may also ask for the permission to access gallery or other storage areas so that photos can be added to perform the crop feature.
Multi resize compress crop photo in batch PicTools
As the name suggests, Multi resize compress crop photo in batch PicTools, is a multipurpose Android app. Its homepage link is here. You can use it to compress images, resize images, change resolution, optimize images, crop images in batch, etc. The free plan lets you select 25 images at once and crop them.
You can crop images in free mode or select pre-defined ratio. The available ratios are 1:1, 4:3, and 16:9. Use any option and crop the images. When the images are cropped, it also provides the feature to preview thumbnails of original and cropped images side by side. After that, you can open any image in the gallery and use it.
Photo Resizer (Homepage) is also a useful Android app. It has features similar to PicTools. For example, you can batch resize images and view the input and output images side by side. The feature to crop the input images and view the output side by side is also available. Just before Resize option, there is a Crop option available for each input image.
Use the Crop option and you can either select a pre-defined ratio or use custom size. Available ratios are 9:16, 2:3, 4:3, 16:9, etc. Using the Custom option, you can enter the width and height manually and then crop the image. This way you can crop input images with this batch image crop Android app.
While there are tons of image crop Android apps already present, those apps miss bulk crop feature. For cropping multiple images quickly, these two apps are helpful. Among these apps, I prefer PicTools app. You can crop 25 images together which would save a lot of time.
