Collage Maker 如何透過用戶端 canvas、免上載方式保障相片私隱
How we keep photo collages private: client-side canvas, no upload
Collage Maker 在瀏覽器處理相片解碼、拼貼排版及 PNG/JPG 匯出，毋須把相片上載至伺服器。草稿可留在瀏覽器儲存空間，下載毋須帳戶，匯出亦沒有浮水印。選用 Pip 助理時只會傳送文字要求，不會傳送相片；手動工具仍可在不使用該服務時離線操作。
Most online collage tools upload your images to a server before they can layout or export. We wanted the opposite: a collage maker that never needs your photos to leave the device.
What “local” means here
In Collage Maker (https://collagemaker.org/), image decode, layout, and PNG/JPG export happen in the browser. Drafts can stay in that browser’s storage. There is no account required to download, and exports have no watermark.
UX choices that follow from privacy
- Full photo by default — keep whole images instead of silently cropping faces.
- HEIC on-device — convert iPhone photos in the browser so they are not uploaded for conversion.
- Optional assistant — if users ask Pip for a style, only the written request (not the photos) is sent; manual tools still work offline of that service.
What we are not claiming
We are not publishing benchmarks or user counts in this post. If you try the tool, tell us where mobile layout or print sizing still feels rough.
