This Pic Can Change · Support
Updated: 12 October 2026.
The app supports iOS/iPadOS 17 and later. Its current interface is in Simplified Chinese; translated labels below are paired with Chinese UI names where useful. The app’s Chinese name is 这图能改.
Common places to start
- Photo and video tools: Open Tools (“工具”) and choose one of the seven on-device image and video tools. Screenshot Delivery (“截图交付助手”) can join, redact, watermark, and export screenshots to a target size.
- AI image generation or editing: Open Tools (“工具”) → AI Creation (“AI 创作”), then choose AI Generate (“AI 生图”) or AI Edit (“AI 改图”).
- Configure an AI service: Open Settings (“设置”) → AI Service Configuration (“AI 服务配置”).
- Purchase or restore: Open Settings (“设置”) → Permanent Unlock (“永久解锁”) or Restore Purchases (“恢复购买”).
- Privacy information: Open Settings (“设置”) → Privacy (“隐私说明”), or read the privacy policy.
- Recent results: Open the Recent (“最近”) tab at the bottom.
Photo and video processing
How do I process a file?
In Tools (“工具”), choose a feature and import media with the Photos or Files picker. Adjust its options, preview the result, then save or share it. The seven ordinary image tools process media on device and do not overwrite the original. Screenshot Delivery’s redaction and confirmation of text-recognition candidates also happen on device. The app requests permission to add to Photos only when you save a result there. Declining that permission does not prevent processing or use of the system share sheet.
Why did compression miss the target size?
How much a file can be reduced depends on its content. PNG uses lossless encoding and may not meet a target. Keeping the original dimensions can also limit further reduction. Check the actual file size and pixel dimensions shown on the result screen.
Why did HDR photo or video colors change?
The current version does not guarantee preservation of HDR highlights or color. Converting HDR media may change its tone.
AI services and charges
How do I configure and check an AI service?
Open Settings (“设置”) → AI Service Configuration (“AI 服务配置”), choose a provider, save your own API key, and enter or choose a model. A connection check sends the key to the receiving host shown in the app to fetch a supported model list. It does not send photos or prompts and does not request image generation. ZenMux Gemini Vertex has no model-list request; it only checks the configuration on device. A model appearing in a list does not mean your account can generate or edit images with it.
Why might AI image editing fail?
Image-input support differs by service and model. Before submitting a reference image, check that the provider says the model supports image editing or reference-image input. For a first submission and when you change the service address, protocol, or mode, the app shows the receiving host and content and waits for confirmation. Declining confirmation does not start the task.
Does AI use the app’s weekly free allowance?
No. AI requests use the API key you configure, and charges are set by that provider and account. They are separate from the app’s free allowance and permanent version. A provider may continue processing or billing after a request is submitted, so cancelling the wait may not stop charges. Check the provider, model, account access, and price before submitting.
What should I do if I see “Pending Downloads”?
Return to Tools (“工具”), open Pending Downloads (“待下载结果”), and choose “Download again” (“重新下载结果”). This downloads an image that was already generated; it does not submit another generation or editing request. The provider’s temporary link may expire. Choosing “Remove download record” (“移除下载记录”) deletes the recovery link and reference image stored on device, after which you cannot retry from this screen.
Where can I clear an AI draft, history item, or API key?
Choose “Clear draft” (“清除草稿”) in AI Generate (“AI 生图”) or AI Edit (“AI 改图”); delete the relevant item in the Recent (“最近”) tab; or clear the current address’s key in Settings (“设置”) → AI Service Configuration (“AI 服务配置”). These actions manage local app data. They do not remove copies saved to Photos or shared with another app, or data a provider has retained. Clearing a key does not revoke it with the provider; revoke it in the provider’s account. Do not send API keys, authorization information, private photos, or full prompts to support.
Weekly allowance and permanent version
The seven image and video tools include 20 successful free processing uses per week, resetting at 00:00 Monday in the device’s local time. Importing, previewing, failing, and cancelling do not use a count. The permanent version is a one-time, non-consumable purchase for unlimited use of all local tools; it is not a subscription and does not renew. The current App Store price shown in the app applies. Restore purchases with the Apple Account used for the original purchase.
Home screen widgets
Set up the photo widget in Tools (“工具”) → Home Screen Features (“桌面玩法”), choose 1 to 10 photos, and drag thumbnails to reorder them. iOS schedules rotation, so the actual refresh time may vary. Photos fill the widget and may be cropped at the edges; animated images show only their first frame. Four games are also available under Home Screen Features. Photos and progress are stored in the device’s shared app directory and do not use image-processing counts.
Contact support
Please include your device model, iOS version, app version, feature name, service host, protocol, model, and error message. Remove keys, tokens, and authorization information first. We usually do not need an API key, original photo or video, or full prompt to begin investigating.
