About Wirin: Firma y edita PDF
Wirin means "stroke" or "writing" in Mapudungun, the language of the Mapuche people. It's the simplest way to sign, fill out, and organize PDF documents on your phone, without uploading them anywhere.
SIGN IN SECONDS
Create your signature by drawing it with your finger, writing your name in cursive, or from a photo of your signature on paper: Wirin removes the background and lets you adjust the result. Tap where it goes, and you're done. Move it, enlarge it, or delete it whenever you want.
FILL OUT ANY FORM
Write in the fields of PDF forms or directly on flat documents. Add checkmarks ✓, today's date, and your saved information (name, RUT [Chilean ID number], email) with a single tap.
SEARCHABLE SCANS (OCR)
Wirin recognizes the text of scanned documents directly on your phone, without an internet connection. Then you can search for and copy the text from the scan.
ORGANIZE YOUR PAGES
Reorder, rotate, and delete pages, insert pages from another PDF, merge multiple PDFs into one, or separate pages into individual files.
READY TO SEND
Save a signed copy with everything fixed or share it directly via WhatsApp, email, or any app you like. You can also print it.
PRIVATE
Your documents, signatures, and data never leave your phone. No accounts, no servers, no ads.
FREE TO READ
Opening, reading, searching, and printing PDFs is free. The tools (signing, filling out, OCR, organizing, exporting, and sharing signed documents) require an annual Wirin subscription, with a 2-week free trial. The subscription automatically renews each year until you cancel it on Google Play.
