免费下载、导入、参数调整和预览比较都免费。任意保存、系统分享或文件导出，都需要同一个一次性永久解锁；没有订阅，也没有按照片张数收费。

Downloading, importing, adjusting settings, and previewing comparisons are free. Any saving, system sharing, or file export requires the same one-time lifetime purchase. There is no subscription or per-photo charge.

有些原图只在 iCloud 照片或其他云端文件位置中。系统需要先下载可处理的原文件，这不表示轻图将照片上传到开发者服务器。请确认网络后重试，或先在系统照片/文件 App 中下载原文件。

Some originals are stored only in iCloud Photos or other cloud-file locations. The system must download the source before it can be processed; PicLean does not upload it to developer servers. Retry with a connection, or download it in Photos or Files first.

iOS 17 及以上的 iPhone 与 iPad。App 支持简体中文和英文，可在设置中切换；首次引导介绍处理流程、购买与权限。

iPhone and iPad with iOS 17 or later. The app supports Simplified Chinese and English, with a language switch in Settings. Onboarding explains processing, purchasing, and permissions.

JPEG 适合广泛分享；PNG 适合需要透明的静态图或无损像素编码；HEIC 适合支持该格式的设备与服务；WebP 适合支持它的网站和应用，轻图使用可调的有损质量编码并可保留透明。目标应用的格式兼容性请先检查。

JPEG is widely compatible for sharing. PNG is useful for transparent still images and lossless pixel encoding. HEIC suits devices and services that support it. WebP suits compatible websites and apps; PicLean uses adjustable lossy encoding and can retain transparency. Check the destination’s format support first.

PNG 使用无损像素编码，不能靠 JPEG 式的有损质量滑块降低质量。你可以等比缩小尺寸，或选择适合用途的 JPEG、HEIC、WebP。实际体积由照片内容、尺寸、格式和参数共同决定；转换后有时也可能更大。

PNG uses lossless pixel encoding rather than JPEG-style lossy quality adjustment. You can scale dimensions down or choose JPEG, HEIC, or WebP when suitable. File size depends on content, dimensions, format, and settings; a converted file can sometimes be larger.

PNG 与 WebP 可保留透明；透明照片转 JPEG 会加白色背景，App 会提前提示。所有输出为 8-bit sRGB 静态 SDR 图片，不保留 HDR、深度或动图/实况的完整呈现。请检查比较预览；颜色、亮度和细节可能因转换改变。

PNG and WebP can retain transparency. JPEG conversion adds a white background to transparent images, with an advance notice. All outputs are 8-bit sRGB still SDR images, without HDR, depth, or the full animated/Live Photo presentation. Review the comparison; conversion can change color, brightness, and detail.

请先查看每张照片的结果或错误提示。可能原因包括源文件无法下载、格式无法读取或设备空间不足。处理时间和可用内存取决于机型、照片尺寸与批量数量；可减少批量张数后重试。只导出你确认成功的结果。

Check each photo’s result or error first. Causes can include a source that cannot be downloaded, an unreadable format, or insufficient device storage. Processing time and available memory vary with device, image dimensions, and batch size. Try a smaller batch and export only results you have confirmed.

一次购买解锁当前所有保存、分享与导出功能，包含单张和批量处理后的结果。一次性永久解锁价格为美国商店 US$1.99、中国大陆商店 ¥12；其他地区由 Apple 显示当地售价。实际金额以系统购买页面为准，无订阅。

One purchase unlocks all current saving, sharing, and exporting, including single-photo and batch results. The one-time price is US$1.99 in the US and ¥12 in mainland China; Apple displays local prices elsewhere. The system purchase sheet shows the actual amount. There is no subscription.

连接网络，使用原购买的 Apple 账户，在设置或购买页面选择“恢复购买”。恢复的是永久解锁权限，不是临时照片或已清理的操作摘要。退款或购买撤销可能移除权限。

Connect to the internet with the Apple Account that made the purchase, then choose Restore Purchases in Settings or the purchase screen. This restores lifetime access, not temporary photos or cleared summaries. Refunds or purchase revocations may remove access.

确认网络、Apple 账户和 App Store 可用后重试。待批准的购买可能需要等待确认；已完成的购买可尝试恢复。若持续失败，请向支持提供提示文字、机型、系统与 App 版本，不要发送支付卡资料或密码。

Check your connection, Apple Account, and App Store availability, then retry. Pending purchases may need approval; completed purchases can be restored. If the issue persists, send support the displayed message, device, iOS version, and app version, without payment-card details or passwords.

不会。TestFlight 使用 Apple 的沙盒购买，不产生实际费用。测试版的购买或恢复成功不代表正式商店商品已获批或真实购买已完成。正式版只通过 App Store 内购付款。

No. TestFlight uses Apple’s sandbox for purchases and does not incur actual charges. Successful beta purchasing or restoring does not prove production approval or a real purchase. The production app accepts payment only through App Store in-app purchase.

不会。清理的是 App 临时导入、预览与输出文件，不会改动源照片，也不会删除已经保存到相册或文件的副本。App 下次启动时会清理上一会话临时照片。

No. Cleanup removes the app’s temporary imports, previews, and outputs. It does not modify source photos or delete copies already saved to Photos or Files. The app clears temporary photos from the previous session on its next launch.

导出副本默认不保留支持的 GPS 位置元数据；设置中可以关闭这个选项。原图不变。GPS 移除不会隐藏照片画面里的地址、人物或地标，分享前仍请检查画面和文件。

Exported copies remove supported GPS location metadata by default; you can turn that setting off. The original stays unchanged. GPS removal does not hide addresses, people, or landmarks visible in the image, so check both the image and file before sharing.

不会。永久保存的操作摘要只包含处理时间、张数、格式与原始/导出体积，不保存照片副本或缩略图。照片只在当前操作会话临时缓存；导出文件由你选择的保存位置管理。

No. Persistent summaries contain only the time, count, format, and original/exported file sizes, without photo copies or thumbnails. Photos are temporarily cached for the current session. Your chosen destination manages exported files.
