Why MiniMax?

Online converters upload your files to a server — yours never leave your computer. This software is provided as-is, without warranty of any kind. If you find bugs, please report them — we'll try to fix them asap :)

200+ Formats

Images, documents, PDFs, spreadsheets, presentations, audio, video, archives, QR codes, and more.

Batch Processing

Drop an entire folder. Convert hundreds of files at once. No limits, no watermarks.

16 Languages

English, Spanish, French, German, Chinese, Japanese, Korean, Arabic, and 8 more.

PDF Security

Encrypt, decrypt, password-protect. Merge, split, rotate, extract. Full PDF toolkit.

OCR Built-in

Extract text from scanned documents and images. Powered by Tesseract.

Drag & Drop

No menus to dig through. Drag files in, pick a format, done. That simple.

Combine & Arrange

Drop a mix of documents, images, and PDFs. Merge them into one PDF or slideshow. Reorder or delete pages before saving.

Subtitles & Lyrics

Drop a video → get a sidecar `.srt` subtitle file. Drop an audio file → get the lyrics as a clean text file with verse breaks where the singer pauses. Powered by Whisper AI, runs offline, works in any language.

Remove Background

Drop an image, click Remove BG, get a transparent PNG. Powered by the U2Net AI model running locally — no uploads, no subscriptions, no daily limits. Great for product photos, social media graphics, and layered design.

AI Upscaling

Drop an image, pick 2×, 3×, or 4×, tick “Use AI”. Two presets — one tuned for photos, one for anime and illustrations. Uses your GPU when available (Vulkan on Windows / Linux / macOS); falls back to CPU when not. All offline, no cloud round-trip.

Add Cover Art

Drop one or more audio files, click Add Cover, drop the image. Embeds into MP3, M4A, and FLAC in place. JPG and PNG go in directly; HEIC, WEBP, BMP, TIFF and the rest auto-convert to JPEG first. Works on whole batches at once.

Download from URLs

Drop or paste a media URL from your favourite sites. MiniMax pulls the video or audio and drops you straight into the regular conversion screen. Pick a format, trim, or batch the same way as a local file.

Rip & Burn Audio CDs

Rip audio CDs to FLAC or MP3 with names, covers and tags filled in automatically — even from scratched discs. Burn music CDs any car stereo can play, data discs up to Blu-ray, and .iso images, with every burn verified. Rewritables erase in place.

Disc Images

Create `.iso` or `.bin`/`.cue` disc images from any files, split archives into equal-size volumes, and mount images as virtual drives with one click — no administrator rights on Windows, macOS, or Linux. Every image is verified after creation.

CAD & BIM Models

Drop STEP or IGES models and get printable STL, OBJ, PLY, GLB, glTF or 3MF — plus a PNG preview. IFC building models convert to 3D formats, an SVG floor plan, or XML. The conversion engine downloads once on first use and works offline after that.

// supported\_formats

What formats does MiniMax convert?

Convert PDFs to Word for editing, or to JPG for sharing and archival. Convert audio to MP3 for portable playback or FLAC for lossless storage. Convert ebooks between Kindle and EPUB to read on any device. Convert video to MP4 for universal playback or to subtitles for accessibility. Convert spreadsheets to CSV for data work. Each conversion runs offline so private files stay private.

// how\_to

How do I use MiniMax Converter?

The easiest way to convert files: drag, drop, done. Here are the most common workflows users ask about.

How do I convert a PDF to Word (DOCX)?

Drag your PDF into the app window. Pick DOCX from the format list. Choose Visual mode if you want the original layout preserved as floating text frames, or Clean mode if you want flowing editable paragraphs. The whole conversion runs offline — your file never touches an external server.

How do I generate subtitles for a video?

Drop the video file. Click the Transcribe button. Pick "Add timestamps" — you get a sidecar .srt subtitle file next to the source. Powered by Whisper AI running on your computer; the first run downloads a 142 MB base model into a local cache that all future runs reuse. Works for 99 languages with auto-detection.

How do I batch convert lots of files at once?

Drag a whole folder or any number of files into the window in a single drop. Pick the target format. Watch real-time per-file progress. There is no count limit, no watermark, and no online queue — everything runs locally on your CPU. Mixed drops of documents, images, and PDFs can also be combined into a single PDF or PowerPoint.

How do I remove a background from an image?

Drop the image. Click the "Remove BG" button on the conversion screen. The U2Net AI model does the work locally — output is a transparent PNG named <source>\_nobg.png, ready for product photography, social media graphics, or layered design files. The model auto-downloads on first use and is cached for all later images.

How do I generate lyrics from a song or audio recording?

Drop the audio file. Click Transcribe. Pick "Lyrics form" — you get a clean .txt with one line per segment and a blank line at every silence longer than 2 seconds, so verse breaks read naturally. Powered by Whisper AI running locally on your computer; the first run downloads a 142 MB base model that all later runs reuse. Supports 99 languages with auto-detection.
