EDIT, ANNOTATE, AND SIGN
Use a contextual toolbar to work directly on the PDF:

TRULY EDITABLE TEXT
Add text to the PDF and continue editing the same object after insertion. Change content, font size, normal, bold, or italic style, color, and box width. Use Enter to create line breaks or adjust the box to keep the text on a single line. Objects remain within the page boundaries and are only saved when you confirm the position.

CONVERT AND SCAN

• Convert PDF pages to PNG or JPG images.
• Convert HTML or web pages to PDF.
• Apply OCR to create searchable PDFs.
• Extract selectable text and save as TXT.

COMPRESS, PROTECT, AND REPAIR
Reduce PDF size without converting text to images. Protect documents with passwords and permissions, create an unlocked copy when you have the password, flatten completed forms, and attempt to reconstruct PDF files with damaged structures.
CUSTOMIZE YOUR DOCUMENTS
Add text or image watermarks, number pages, and edit metadata such as title, author, subject, and keywords. Compress images, adjust dimensions, convert formats, and remove EXIF metadata when necessary.
HISTORY AND PRODUCTIVITY

Save a copy with your edits, export pages as images, share documents with other apps, and print using printers configured on Android.
