What this tool does
Design background and device frame once, fill a locale copy grid for each slide, then export App Store / Android size ZIPs in per-language folders. Canvas + JSZip stay in the browser — no upload, no paid translation API. Pair with /preview for single-locale polish.
How to use
- Upload 1–8 shots and set background/device frame once.
- Fill locale titles/subtitles; copy empty cells from a source language.
- Export a ZIP with folders per language (6.9″/6.3″/1080×1920).
FAQ
Are images uploaded?
No. Screenshots and copy stay in browser memory; the ZIP is built locally.
How is this different from /preview?
/preview is for single-locale polish, templates, and master multi-size packs. This tool is for one design × many locale captions. Use both.
Does it auto-translate?
No. We intentionally skip paid APIs like DeepL/Google Translate. You supply copy; we keep layout consistent and batch-export.
Arabic / RTL?
Pick ar — inputs and canvas titles render right-to-left.
Which export sizes?
Optional iPhone 6.9″ 1320×2868, iPhone 6.3″ 1206×2622, Android 1080×1920 — matching site DEVICE_PRESETS.
