有什么可以帮你?
先查看常见问题,或者通过页面中的联系方式找到我们。
为什么结果小于目标大小?
目标大小代表文件上限,而不是必须精确达到的大小。LessKB 会确保输出不超过所选限制。图片格式和画面内容会影响最终体积。
为什么无法达到非常小的目标?
图片尺寸、透明区域或格式限制可能导致目标无法实现。可以改用 JPEG/HEIC,允许进一步缩小尺寸,或者适当提高目标大小。
如何恢复 LessKB Pro?
打开购买页面或“设置”,选择“恢复购买”,并使用最初购买终身版的 Apple 账户。恢复购买不会重复扣费。
为什么购买价格一直在加载?
请确认设备可以连接 App Store,稍后完全关闭并重新打开 LessKB。如果问题持续,请确认 Apple 账户所在地区允许购买该商品。
如何删除压缩记录?
打开“单张压缩记录”,选择“清空”并确认。本机保存的单张历史原图、压缩结果、缩略图和统计信息都会删除。批量任务不会写入该记录。
批量压缩后会自动删除原图吗?
不会。LessKB 会先保存成功压缩的副本,再让你逐张检查结果。只有你主动选择删除原图并在 iOS 系统提示中再次确认后,对应原图才会被删除;失败项目不会进入删除范围。
LessKB 会上传我的照片吗?
不会。压缩完全在设备本地完成。只有你主动保存或分享时,系统才会把结果提供给照片图库或你选择的其他 App。
Why is the result smaller than the target?
The target is a maximum file size, not a size that must be matched exactly. LessKB keeps the output below the selected limit. Image format and content affect the final size.
Why can't LessKB reach a very small target?
Image dimensions, transparency, or format limits may make the target impossible. Try JPEG or HEIC, allow further downscaling, or raise the target size.
How do I restore LessKB Pro?
Open the purchase page or Settings, select Restore Purchases, and use the Apple Account that originally purchased the lifetime unlock. You will not be charged again.
Why does the purchase price keep loading?
Confirm that the device can connect to the App Store, then fully close and reopen LessKB. Also confirm that the product is available in your Apple Account region.
How do I clear compression history?
Open Single-photo Compression History, choose Clear, and confirm. Stored source images, results, thumbnails, and statistics are removed. Batch jobs are not added to this history.
Does batch compression automatically remove originals?
No. LessKB first saves successful compressed copies and lets you inspect each result. Originals are removed only after you choose that action and confirm the iOS system prompt. Failed items are never included.
Does LessKB upload my photos?
No. Compression runs entirely on your device. Photos leave the app only when you explicitly save or share them through the system interface.
