Every file. In your flow.

Everyday editing

Create, open, edit, save, and Save As for text, logs, subtitles, source code, and configuration files.

Focus on the content

Syntax highlighting, line numbers, horizontal scrolling, font sizing, immersive reading, and an inline find-and-replace panel.

Care for the original

Detect common encodings and preserve the original encoding and BOM when saving. Detect external changes and recover unsaved text drafts.

Size-aware handling

Full editing up to 20 MiB; lightweight editing at 20–50 MiB; preview and confirmation before lightweight editing at 50–100 MiB; a sampled preview above 100 MiB.

Good to knowLightweight mode disables highlighting, line numbers, full-text search, live previews, and structured formatting. Saving still writes the complete file.

Markdown writing

Edit Markdown source, preview the rendered result, and export notes as HTML or PDF.

Web previews

Edit HTML source and preview the page to inspect and refine local web documents.

SVG graphics

Preview vector artwork, edit SVG source, and validate or format its XML.

Good to knowThese are source editors with previews, not visual page builders. Live previews depend on the file’s editing mode.

JSON tools

Validate syntax, format indentation, or minify JSON to inspect and tidy its structure.

Structured text

Work with YAML, XML, Plist, and configuration files. YAML has basic checks; XML and Plist have validation and formatting.

Format conversion

Convert between JSON, YAML, XML, Plist, and configuration text, and export a new file.

CSV table editing

Switch between text and table modes, edit cells, and add or remove rows and columns.

Good to knowData types differ across formats, so review converted results. CSV editing is not Excel workbook editing.

Source editing

Open .tex, .latex, .sty, .cls, and .bib files and edit with syntax highlighting.

Formula previews

Check how formulas render while working on the source.

Document structure

Use the outline and checks to review your document’s structure.

PDF output

Preview and export PDFs with the built-in offline processing engine, without installing a separate TeX environment.

Good to knowCompatibility is limited to the built-in engine. Not every desktop TeX package, template, or complex project is supported.

Source and map views

Edit KML’s XML source and switch to a map preview to inspect geographic content.

Common geometry

Display points, lines, polygons, and MultiGeometry with basic styles and name labels.

Automatic framing

Fit the map to the file’s geographic bounds to review routes and areas.

Good to knowGroundOverlay, NetworkLink, 3D Model, and gx:Track are not rendered; their source is retained. Base maps may need a network connection.

Canvas management

Switch, create, duplicate, delete, and rename canvases.

Topic trees

Edit topic text; add children or siblings; duplicate, delete, and move topics up or down.

Editing controls

Undo and redo changes, save to the original, or save a separate copy.

Flexible exports

Export PDF, PNG, SVG, or Markdown and TXT outlines.

Good to knowSupports core topic trees in newer content.json-based XMind files. Legacy content.xml files, complex relationships, styles, and attachments are not guaranteed to be editable.

Read and annotate

Highlight, underline, add text notes, and draw with pen, pencil, or marker, with an eraser and undo.

Signatures and overlays

Save and reuse handwritten signatures, add text or images, and move, resize, rotate, or delete editable marks.

Page management

Add blank pages or pages from another PDF. Delete, duplicate, rotate, reorder, crop, and reset crops.

Merge and split

Merge documents by importing pages. Split each page into a ZIP or extract a selected range into a new PDF.

Good to knowPDF support focuses on annotations and page-level changes. It does not include body-text reflow or full form editing.

Scan and assemble

Scan paper into a PDF or combine selected images, in order, into a multipage document.

Offline OCR

Extract existing text and recognize scanned pages into TXT, or add a text layer to create a searchable PDF.

Compress and protect

Choose from three compression levels and compare file sizes. Protect an exported copy with an opening password.

Watermarks and page numbers

Add single or tiled text watermarks with position, style, opacity, and angle controls. Add continuous page numbers with a custom start and format.

Convert and deliver

Export PDF pages as PNGs in a ZIP or image slides in a PPTX. Convert OFD to PDF, then annotate and share it.

Good to knowPDF compression re-renders pages; PPTX slides contain images. OFD conversion focuses on text, images, and basic layout, so complex fonts and graphics may be simplified.

Image adjustments

Rotate, flip, crop, resize, and adjust brightness, contrast, and saturation.

Editable overlays

Add text, brush strokes, and mosaic layers. Adjust layer position and rotation, with undo and redo.

Format options

Export edited images as PNG, JPEG, or PDF. Batch conversion supports JPEG, PNG, HEIC, static WebP, TIFF, GIF, BMP, JPEG 2000, ICO, TGA, and OpenEXR.

Size control

Set conversion quality or compress to JPEG with a target size in KB, resizing when necessary. Package multiple results as a ZIP.

Watermarks and metadata

Add watermarks in bulk, or re-encode images to remove EXIF metadata such as location and device information.

Good to knowPNG and JPEG can be saved in place when permitted; other formats generally use copies. Batch conversion and compression may not retain animation or all original metadata.

Playback controls

Seek forward or back, change speed, mute, and switch between fitting and filling the video frame.

Light video editing

Trim a time range, rotate in 90° steps, remove audio, and export MP4 at different quality levels, with progress and cancellation.

External subtitles

Import SRT subtitles and adjust encoding, size, color, position, background, and timing offset. Show or hide them during playback.

Extract and trim audio

Export a selected segment from video or audio as M4A, AAC, WAV, FLAC, AIFF, or CAF, with applicable bitrate or bit-depth settings.

Audio playback

Use system previews to play common formats including MP3, WAV, M4A, AAC, and FLAC.

Good to knowPlayback and export depend on system codec support. SRT subtitles are playback overlays and are not burned into exported MP4 files.

Everyday organization

Create files and folders; import documents and photos; rename, move, copy, delete, or select multiple items. Search, switch list/grid views, and sort by name, date, or size.

Rule-based filing

Move matching files in the current folder into a destination folder using name, extension, date, and size rules.

Frequent files

Reopen recent files, add notes or pin items, and open frequent files from a Home Screen widget.

External locations

Mount folders or individual files from the Files app. Repair expired access or unmount a location, and work in place when authorized.

Recovery and saving

Restore items from the internal 30-day recycle bin. Editors use in-place saving, a copy, or Save As depending on the format and provider permissions.

Good to knowDeletes from mounted folders or remote locations do not enter the internal recycle bin. In-place writing depends on the file provider and access permissions.

Browse before extracting

Explore a folder tree, search paths, temporarily preview individual entries, or extract an entire archive into your file space.

Broad reading support

Read ZIP, RAR, 7Z, TAR and common compressed variants, plus CAB, CPIO, XAR, LHA, ISO 9660, and more.

Create archives

Create ZIP, 7Z, TAR, TAR.GZ, TAR.BZ2, or TAR.XZ with applicable compression-level and algorithm controls.

Password protection

Read encrypted ZIP and 7Z files. Create ZIP AES-256 or traditional encryption, or 7Z AES-256 with optional filename encryption and solid compression.

Split volumes and checks

Create split ZIP or 7Z archives. Recognize common ZIP, 7Z, and RAR volume sets, warn about missing parts, and check 7Z integrity with processing progress.

Good to knowCompatibility depends on the container, compression, and encryption method. Compression creates new archives; it does not edit entries inside an original archive.

Remote browsing

Browse, open, and import files through WebDAV, FTP, or SFTP, including recursive folder imports.

SFTP file management

Upload, overwrite, create folders, rename, move, and delete. Edit a remote file and write it back to its original remote path.

SSH authentication

Use a username and password or an OpenSSH Ed25519/RSA private key. Passwords, keys, and passphrases are stored in the local Keychain.

Host verification

Confirm the host fingerprint on first connection. Changed host keys block connections until trust is explicitly addressed.

Interactive terminal

Use an ANSI / VT100-compatible SSH terminal with up to six tabs. Minimize while keeping sessions active in the app, and manually synchronize directories.

Good to knowWebDAV and FTP currently provide reading and import. SFTP deletes are permanent. SSH sessions disconnect when the app enters the background.

Browser access

Start sharing on the same Wi-Fi or hotspot network. Open the displayed address or scan its QR code to access the shared space.

Access code

Enter a six-digit code to open the sharing page. View and copy connection addresses on your device.

Transfers both ways

Browse folders, download files or entire folders as ZIPs, upload multiple files, and create folders, rename, or delete from the browser.

WebDAV and cable transfers

Connect Finder or a WebDAV client to the device’s sharing address to read and write the internal file space. You can also transfer files over a cable using Finder / iTunes file sharing.

Active when needed

Network sharing stops when you leave its page or put the app in the background.

Good to knowSharing uses a local HTTP server and requires a mutually reachable network. It is not public cloud storage or a background sync service.

Office documents

Read Word, Excel, PowerPoint, Pages, Numbers, and Keynote files through system Quick Look previews.

Offline CAD

Open DWG and DXF model space. Zoom, pan, fit to view, and toggle layers for 2D and selected 3D lines, faces, and meshes.

3D viewing

Switch supported CAD content between wireframe and shaded views, standard angles, and orthographic or perspective projection.

More file types

Preview EPUB, USD / USDZ / Reality, fonts, contacts, and calendar files when supported by the system.

Fallback inspection

Identify files using extensions, system types, and headers. When a normal preview is unavailable, try raw text or a hexadecimal sample, with confirmed safe text available for editing.

Good to knowOffice and CAD are read-only. CAD input is limited to 25 MiB and generated preview data to 64 MiB. ACIS solids, external references, layout viewports, and precise SHX fonts are not fully supported. Database files do not have a SQL query editor.

TXT book mode

Switch TXT and TEXT files between the editor and a paginated reader, with the chosen mode remembered per file.

Comfortable layout

Adjust fonts, size, line spacing, layout, background, and encoding. Navigate chapters through a contents view, and read large text files in pages.

Read aloud

Choose system voices and reading speed, pause or resume, and jump to the previous or next segment.

Appearance and languages

Light and dark appearances, with Simplified Chinese, Traditional Chinese, English, German, Spanish, French, Japanese, and Korean interfaces.

Choose an icon

Keep the original icon or choose from six themes, each with light and dark versions.

Good to knowDedicated pagination and read-aloud features are for TXT / TEXT. EPUB uses system previews with a different feature set.

Compare and replace

Compare two texts line by line and export a difference report. Apply literal replacements across text or code files, inspect match counts, and preserve encoding, BOM, and extensions.

Batch renaming

Generate renamed copies with a shared prefix and sequence numbers, packaged as a ZIP, while keeping files in the original directory.

Find space usage

Find duplicates with size screening and SHA-256 content checks, or scan for files above a size threshold. Export CSV reports.

QR creation

Create text, URL, and Wi-Fi QR codes with a live preview. Customize module shape, margins, correction level, colors, size, and center icon, then export PNG.

Keep going with a result

Launch relevant tools from selected files. Preview, save and open, share, save to the source directory, or continue processing the output.

Good to knowStandalone processing tools create new results without overwriting input files. Duplicate and large-file scans produce reports; they do not automatically delete files.

Separate storage

Enter with system authentication. Files and directory information are encrypted with AES-GCM.

Familiar organization

Create, import, search, rename, copy, move, and delete inside the encrypted space, with list and grid views.

Keep editing

Open a temporary decrypted copy in a compatible editor, then return saved changes to encrypted storage.

Less exposure

Private files stay out of ordinary recents, widgets, and deep-link records. The app obscures content and locks the space when entering the background.

Restore and export

Use a separate 30-day recycle bin. Explicitly export a decrypted copy when you need to use the file elsewhere.

Good to knowThis encryption applies only to content inside private space. Exported decrypted copies and the ordinary file space are outside that protection.
