How to use the batch image cropper
- Choose or drop images. You can add many at once and pick which one to preview from the list.
- Choose the crop mode. Ratio mode only needs a ratio, and area mode lets you drag on the left photo to choose the part. If you need the same pixel size, turn it on and enter numbers.
- Check the preview on the right, then save this photo only, or for many photos save all with the same settings as a ZIP.
How photos get cropped
This tool draws the photo on a hidden canvas and copies only the chosen rectangle into a new image. In ratio mode it compares the photo’s aspect ratio with the target ratio, cuts off the extra side, and keeps the center or one side depending on the anchor position.
In area mode, the chosen area is remembered as proportions of the photo size and applied at the same position to every photo. So photos of different sizes are cropped at a similar place, but photos with different aspect ratios can end up with a slightly different shape.
With same pixel size on, the cropped part is enlarged or reduced to the set size. When ratios differ, the extra part is cut so the image fills the size around its center and does not look stretched.
Uses and tips
It is most used to make shop product photos square, YouTube thumbnails 16:9, or Instagram posts 1:1 or 4:5. Making many photos the same size at once cuts a lot of repetitive work.
For photos where the subject is off to one side, such as ID or profile photos, area mode lets you place the face. The area chosen on the first photo is applied in the same proportions to the others, which suits sets of similarly shot photos.
If photo sizes differ a lot, turn on same pixel size to unify the result. For output format, JPG or WebP suits web posting, and PNG suits photos that need transparency or more editing.
To shrink file size itself, use the Image Compress and Resize tool, and to add watermarks to many photos, use the Batch Watermark tool.
For sets such as product photos where the subject is in the same place, ratio mode with a center anchor needs almost no touch-ups. If subjects are in different places, it works better to group similar photos and process them with area mode in batches rather than all at once.
For photos used at a small size, such as profile pictures, turn on same pixel size and make them exactly 400×400 or 1080×1080. When each site asks for a fixed size, you do not have to resize them again.
Because files are never uploaded, even personal photos and original product shots can be cropped and saved within this device only. You can add up to 100 at a time, and very large photos can slow processing, so check the settings on a few first and then process everything. Each result name ends with _crop so it does not get mixed with the originals.
Tips for good crops
- For a square, use ratio 1:1 with the anchor at center.
- If people are near the top, change the anchor to top.
- In area mode, frame the most important part on the first photo.
- If photo sizes vary, turn on same pixel size.
- Click other photos in the list to check the result before saving.
FAQ
What is the difference between ratio mode and area mode?
Ratio mode crops each photo automatically around its center once you pick a ratio such as 1:1 or 16:9. Area mode lets you drag on the photo to choose the part yourself and applies the same position to every photo. Area mode suits photos where the subject is off to one side.
Can I make every image the same pixel size?
Yes. Turn on same pixel size and set width and height, and every result is exactly that size. In ratio mode the crop uses that size’s ratio, and in area mode the selection box is locked to that ratio.
How do I use a custom ratio?
Choose custom ratio in the ratio list and enter the width and height numbers. For example, 5 and 4 crops at 5:4. Decimals work too.
What is the anchor position?
It decides which side to keep when a photo’s ratio differs from the target ratio. Center is the default, choose top for photos with people near the top, or bottom if you want to keep the ground rather than the sky.
Does it change my original files?
No. Originals stay as they are and only the cropped results are saved as new files. _crop is added to each file name to keep it distinct from the original.
Notes & limitations
Cropped results cannot be undone, so keep your originals. Photos are processed only in the browser and are not sent to a server. Many or large photos may take long depending on device memory.
