AxiSubs Simple Subtitle Editor

Eksen Interactive

About this app

AxiSubs is a simple subtitle editor built for touch. Open an ASS or SRT file, or start from a blank project, then time, style and animate every line against your video. When it looks right, burn the subtitles straight into the video on your device.

Made for content creators, fansubbers, translators and anyone adding captions to their videos for accessibility or social media.

What you see is what you export
The live preview is drawn by libass, the same subtitle engine that renders your final video. Outlines, shadows, fonts, positions and transitions look in the preview exactly the way they will in the exported file.

A timeline that fits your thumb
• The playhead stays in the center: swipe to scrub, pinch to zoom
• Tap a block to select it, drag it to move, pull the trim handles to change start and end
• Overlapping lines stack in their own lanes so nothing hides behind anything else
• Set start or end to the playhead with one tap for fast, accurate timing

Every line under control
• See every subtitle with its timing and text in one list
• Edit text, and nudge timings back or forward by 500 ms
• Select many lines and change their style, color and position at once, with the result live in the preview
• Undo and redo for every edit

Advanced subtitle styling
• Font, size, text, outline and shadow colors
• Outline and shadow thickness, bold, italic, alignment and margins
• Per-word styling: select a single word in a line to give just that word its own color or shadow

Transitions
Give lines an entrance and an exit with adjustable durations: Fade, Slide up, down, left or right, Zoom, Pop, Blur, Wipe, Spin, Flip, Tracking and Typewriter. Apply them to one line or many.

Fonts for every script
• 37 free font families included, with coverage for Arabic, Hindi (Devanagari), Thai, Korean, Japanese, and Simplified and Traditional Chinese
• Import your own TTF and OTF fonts
• Get a warning when a font is missing characters your text needs

Burn subtitles into video
FFmpeg is built into the app, so there is no extra app or server to set up. Export to MP4, MKV or MOV, choose Fast, Standard or Quality, and keep the original audio as is. You can also save your work as an .ass file.

Private and offline
Editing, preview and export all run on your device. No account, and your videos are never uploaded.

Never lose your work
AxiSubs backs up your project automatically as you edit and offers to pick up where you left off when you come back.

What’s new

Videos that wouldn't open on some devices (10-bit HEVC/H.264 and AV1 MKV files) now open, with more reliable video export and better stability.
