File conversion that starts in chat

Convert files directly from WhatsApp, Telegram, and LINE.

Send a PDF, Word file, image batch, scan, or voice note. MonFile detects the format, asks what you want to do, converts it in the background, and sends the finished file back in chat.

How it works

No upload portal. No technical file menu. Just chat.

MonFile is for the everyday moment when someone sends a file and asks, "Can you convert this and send it back?" The bot takes that handoff and turns it into a repeatable workflow.

1

Send any work file

Upload a PDF, Word file, spreadsheet, slide deck, scan, screenshot, image batch, or voice instruction inside chat.

2

MonFile detects the format

The bot reads the file type and asks the right next question, like convert, compress, merge, split, or extract text.

3

Get the result back

The heavy conversion runs in the background and the finished file returns to the same conversation.

Tools

The document tasks people ask for most.

MonFile starts with practical conversion work: PDFs, Office documents, scans, screenshots, and batches. The interface stays simple because the conversation carries the context.

Convert to PDF

Office docs, images, scans, slides, and sheets into clean PDFs.

Compress PDF

Reduce file size before forwarding in chat or email.

Merge files

Turn multiple images or PDFs into one organized document.

Split PDF

Pull out only the pages someone asked for.

Extract text

Copy text from PDFs, images, screenshots, and scanned forms.

Voice request

Send a file, then say what you want MonFile to do.

Formats

MonFile detects the upload before it asks the next question.

Users should not need to know whether a file is DOCX, TIFF, or a scanned PDF. MonFile reads the format and suggests actions that make sense for that file or batch.

Voice and batches

It understands the messy way files arrive.

People send several photos, then a voice note. Someone forwards a PDF with no explanation. A team member says "make this small and send as PDF." MonFile keeps the active batch in context and asks only when it needs clarity.

Use cases

A global problem, not a local workaround.

Any team that moves documents through messaging apps has this pain. MonFile makes file help available where the request already happens.

Government and admin teams

Forms, certificates, signed scans, receipts, and letters move through chat every day.

Field and operations teams

Turn mobile photos, scans, and voice instructions into shareable documents without opening a desktop app.

Finance and small businesses

Compress invoices, merge proofs, extract text, and send the final file back quickly.

Students and creators

Bundle screenshots, notes, slide decks, and PDFs into the format someone actually needs.

Trust

Simple for users. Careful behind the scenes.

MonFile separates chat handling, temporary storage, AI instruction understanding, queueing, and deterministic conversion workers. Files are processed for the requested job and beta video uploads are ignored.

Temporary file handling

Files are stored for processing and cleanup rather than becoming a permanent file library.

AI for instructions

The AI layer helps understand user intent. Conversion work runs in dedicated workers.

Multilingual by design

Typed requests, voice instructions, and OCR workflows are designed for global users.
