💡 Tips and Best Practices
🎨 The Magic of Filter Order
Many people don't realize that the order in which filters are applied significantly affects the final result. Image Toolbox lets you manually adjust the filter application order: simply long-press the filter you want to move, and once the sorting interface appears, drag to rearrange.
A general recommendation is to apply basic adjustment filters first (like brightness and contrast), followed by effect filters (like blur and sharpening). By experimenting with different filter order combinations, you can create unique visual effects.
⚡ Save Time with Batch Processing
For users handling large numbers of images, the batch processing feature can save tremendous amounts of time. Simply select multiple images and apply the same operations (resize, compress, convert format, or apply filters).
📐 Precise Crop Ratio Control
When using the crop function, the ratio lock feature ensures the crop area maintains its original aspect ratio. This is especially useful when you need images in standard ratios like 1:1, 4:3, or 16:9.
🔒 Metadata Privacy Protection
Before sharing images, use the metadata editing feature to remove EXIF information, protecting your privacy by preventing the leakage of sensitive data like location and device details.
