All-in-One PDF Editor & Sign

Got a form, contract or consent sheet by email or chat? Skip the print-sign-scan routine and finish it right on your phone.
All-in-One PDF Editor lets you type into a PDF, sign it, stamp it and tidy up its pages in one app.

■ Fill in documents
• Tap a blank field and type – the text lands exactly there
• 4 text sizes, 3 colors (black, blue, red), drag to move, double-tap to edit
• Korean and English fonts built in; Japanese, Traditional Chinese and accented Latin fonts can be downloaded in the app when you need them
• What you see on screen is what gets saved in the PDF

■ Signatures
• Sign with your finger on the signature pad; it's saved as a transparent image
• Create it once and reuse it on any document
• Drag it onto the signature line and resize from the corner

■ Stamps
• Type a name to generate a seal image – round, square or oval, with optional 印 and ink texture
• Or import a photo of your real stamp on white paper; the white background is removed automatically
• Saved stamps are ready to reuse

■ Pen & highlighter
• Pen in 3 colors and 3 widths, pinch with two fingers to zoom
• The highlighter lets the text underneath show through

■ Cover & rewrite
• Hide a mistake with a white box and write over it
• Turn on "Permanently remove covered text" when saving to flatten those pages into images so the original text can't be copied – useful for sensitive details

■ Page tools
• Organize pages: rotate, reorder, delete, or extract only the pages you select
• Split PDF: every page, every N pages, or custom ranges (e.g. 1-3, 4, 5-8)
• Merge PDFs: combine several files in the order you choose
• Images → PDF: turn several photos into one PDF (fit to A4 or keep image size)
• PDF → Image: save selected pages as PNG or JPG (150/220/300 dpi)

■ Made for everyday use
• Open PDFs and photos straight from your file manager, email or messenger via "Open with" or "Share" (a photo opens as a one-page document)
• Your original is never changed – results are saved as new files in Download/my_pdf
• Preview and share results inside the app
• Unsaved edits are restored if the app closes unexpectedly
• Undo support
• Available in English, 한국어, 日本語, 繁體中文, Español, Português and Bahasa Indonesia

■ Your files stay on your phone
• All editing and conversion happens on your device; documents are not uploaded to any server
• No account or sign-in required
• Internet is used only to download extra fonts and to show ads

■ Good to know
• Password-protected PDFs can't be opened yet
• PDFs with form fields are filled by placing text on top of the fields
