Liyun — ލިޔުން

A PDF toolbox that works in Dhivehi. Everything runs in the browser, and files are never uploaded.

• Edit & fill PDF: type Thaana (phonetic keyboard) or English anywhere on the page. Also: ✓/✗ marks, whiteout, a pen, images, and filling real form fields.
• Sign PDF: draw a signature or upload a photo of one (the white background is removed automatically).
• My Files: save PDFs (forms stay editable), create folders, rename, move, duplicate, search. Files are kept in this browser's storage on this device.
• Merge, Split, Organize, Rotate, Page numbers (ސަފުހާ 1), Watermark, JPG → PDF, PDF → JPG

Sign-in & admin

The whole app needs a sign-in. Accounts are kept in users.json in this repo. Passwords are stored as PBKDF2-SHA256 hashes, never in plain text.

• First visit: with an empty users.json, the site asks you to create the first admin account.
• Admin page: go to the account menu and choose Admin. There you can add users, reset passwords, block or unblock accounts, make someone an admin, or delete accounts.
• Publishing changes: click Publish to GitHub to commit users.json using a fine-grained token (this repo only, Contents: read & write). The token is stored only in the admin's browser. Vercel redeploys automatically.
• Limitation: this is a client-side gate for a static site. It keeps casual visitors out, but it's not strong security.

Deploy

It's a static site with no build step: index.html and the bundled libraries (pdf.js 3.11, pdf-lib 1.17, JSZip 3.10). On Vercel, import the repo and choose the Other framework preset with no build command.

Editing

The source is in src/. After a change, run sh src/build.sh to regenerate index.html (it embeds the Faruma font).
