PAPERPATINA · 纸影工坊

Make a copy ready to share.

Watermark, cover private details, clean hidden tags or give digital media a paper finish. Use each tool on its own, or combine them.

Watermarks with a purpose

Six layouts for review copies, ownership marks and signatures. Control text, ink color, opacity and size; adjust placement or tiling for the selected template. Long text fits inside its bounds.

Confidential redaction pen

Replace private details with opaque pixels using a pen or rectangle. PDF pages are rebuilt without the original text layer, annotations or attachments. New PDF marks belong to the current page. Review every page or video frame; blur and pixelation do not provide the same protection.

Inspect metadata before and after

Read image EXIF/GPS/IPTC/XMP, PDF document attributes and video-track tags. Clean original private tags during export, optionally anonymize filenames, then inspect the actual exported files.

Keep the original appearance

Start without a scan filter or watermark. Add only the tools you need, or choose metadata cleanup while retaining existing redaction areas. Original files remain unchanged.

Scan and paper effects

Six scan modes and eight paper styles remain available: grain, halftone, dithering, archive paper, parchment, stains, creases, wear, cyanotype and risograph. Video textures stay stable between frames.

Local editing, deliberate sharing

No app account, advertising SDK or analytics SDK. Media is not uploaded to a developer server. Import images, PDFs and video, save settings and batch export.

Choose how you export

All editing tools are free. Free exports include a bottom-right PaperPatina mark on every image, PDF page and video frame. Remove it with a monthly subscription (US$0.99/month), yearly subscription (US$4.99/year, billed annually), or a permanent one-time purchase (US$9.99). US prices are shown as a reference; Apple displays local prices before purchase. Both subscriptions provide the same ongoing clean-export access while active. Custom watermarks remain.

Testing & availability

Internal beta for invited team members. Requires iOS 17 or later. Available in English and Simplified Chinese. Edits existing media; no camera scanning or OCR.
