Folium: PDF Editor & Signer

Folium is a free PDF editor and PDF signer that works on your phone. Fill in and sign a form, fix a typo, merge PDFs or tidy up the pages, all on your device. Your files are never uploaded anywhere. No account. No subscription. No ads. It works offline. ✍️ FILL IN AND SIGN Type into PDF forms, then add your signature, initials and the date. Draw your signature, or type it in one of three handwriting styles, and keep it for next time. 📝 EDIT THE TEXT THAT'S ALREADY THERE Fix a typo, change a date or update a name in the PDF's own text, without printing and scanning. The old text is really removed, not covered with a white box. 📷 EDIT SCANNED DOCUMENTS TOO A scanned page is read on your phone (in English for now), so you can change a line of text, or move or remove a logo or stamp, just like a regular PDF. 📑 MERGE AND ORGANIZE PAGES Merge PDFs into one, and split, reorder, rotate or pull out pages. 🖍️ MARK IT UP Highlight, draw and add notes, then save a new copy wherever you choose. 🔒 PRIVATE BY DESIGN Folium asks for no permissions. You pick each PDF with Android's own file picker, and every new PDF is built on your phone. Open a PDF from another app or share one to Folium, and it opens right away. Password-protected PDFs open on your phone, and the password is never saved. YOUR PRIVACY Folium has no account, no analytics, no ads and no tracking, and the app sends nothing at all.
