Organize
Arrange, split and combine pages — one lossless rebuild.
Combine files in an order you control via drag-and-drop cards. Lossless; never overwrites a source.
Extract a range like 1-3, 5, 8-10, or burst into one PDF per page — plus advanced split by N pages, chunks or size budget.
Multi-select thumbnails and pull them into a new PDF.
Trash pages in bulk; guarded against emptying the document; fully undoable.
Pick pages from another PDF and drop them at any position, across multiple sources in one save.
Drag tiles or type an exact target position on a page badge.
90° steps applied as a delta, so already-rotated scans stay correct.
One-click exact copy right after the original.
Convert
Layout-faithful exports that run entirely on-device.
Every line placed at its exact position — fonts, sizes, per-line color and real tables preserved. CJK gets the right font slot.
Reconstructs column-aligned tables into worksheets, one sheet per page.
Real editable text boxes, one slide per page, slide size matched to the source.
Export current or every page to PNG/JPG with a quality slider.
Combine PNG, JPG, WebP, GIF, BMP, AVIF — PNG/JPEG embed with no re-encoding.
Bring Word, PowerPoint and images into a single PDF.
Edit
A real in-page text editor plus a full markup suite.
Click any line and retype — redrawn in the document's own embedded font, with ink, background and size auto-sampled.
Drop a draggable, inline-editable text box anywhere, in 100+ languages.
Bold, italic, lists, highlight, per-selection color and exact size with Acrobat-style shortcuts.
Real Multiply-blend highlighter over selected text.
Underline, strikethrough, freehand pen, rectangles and a selective eraser.
Pinned typed comments anywhere, in any language.
True redaction — marked pages flatten to image so hidden content is genuinely gone.
Stamp custom text with adjustable opacity on a 9-position grid; any script.
Auto-number in n, n of N or Roman on a 9-position grid.
Author real fillable fields, or fill and flatten existing ones (CJK supported).
Draw or upload a signature; luminance knockout blends a photo cleanly into the page.
Optimize
Shrink and read your documents.
Three levels; keeps the smaller of lossless repack vs downsample, so text PDFs stay lossless and never grow.
Make scans searchable. English & Korean work fully offline; any other language downloads its model once.
Security
Protect, sign and lock down files — and know the difference.
Real, verified AES-256 encryption that reopens the file to confirm the cipher that actually landed.

Permanently redact PII by pattern (SSN, emails, Korea phone, 주민등록번호), then re-extract to confirm 0 remain.
