よくある質問
What is the Image Cropper tool?
The Image Cropper is a utility designed to trim or cut out specific portions of an image. It allows you to remove unwanted areas, change the aspect ratio, or focus on a particular subject within a photo.
How do I select a specific aspect ratio?
Look for the 'Aspect Ratio' dropdown menu or settings panel before or after uploading your image. You can choose from common presets like 1:1 (Square), 16:9 (Widescreen), or 4:3, or select 'Freeform' to crop manually without constraints.
What image formats are supported?
The tool typically supports standard web formats including JPEG (.jpg, .jpeg), PNG (.png), and WEBP (.webp). Some versions may also support BMP or TIFF files.
Will cropping an image reduce its file size?
Generally, yes. Since cropping removes pixels from the original image, the total data size usually decreases. However, if you crop a very small section and zoom in, the file size might not drop significantly depending on the compression settings.
Is my image data secure when using this tool?
Yes, most client-side croppers process images directly in your web browser. This means your photos are never uploaded to a remote server, ensuring your data remains private and secure on your device.
Can I undo a crop if I make a mistake?
Yes, simply click the 'Reset' or 'Undo' button, or re-upload the original image if the tool does not support multiple undo steps. Always keep a backup of your original file just in case.
