Best File Converter Bots for Telegram (2026)

File format mismatches are a daily friction point: a PDF you need as a Word document, an HEIC photo from an iPhone that Windows cannot open, a voice message you want to save as MP3, a screen recording you need to shrink to send on WhatsApp. Normally you would open a browser, find a converter site, upload your file, wait, download the result, and then share it. Telegram converter bots collapse that process: send the file to the bot, get the converted file back within seconds, without leaving Telegram. This guide covers the best converter bots across four categories: PDF, image, audio, and video. Find more tools in the Utilities category.

Best PDF Converter Bots for Telegram

1. @pdfbot — The Most Complete PDF Tool on Telegram

@pdfbot is the most comprehensive PDF bot available on Telegram. It handles a wide range of PDF operations without requiring any account or subscription for basic tasks.

What @pdfbot can do:

PDF to Word: Send any PDF and receive an editable DOCX file. Works well for text-heavy documents; complex layouts with heavy formatting may need minor cleanup.
PDF to JPG/PNG: Converts each page of a PDF to a separate image file. Useful for extracting specific pages as images or for documents you want to preview without a PDF viewer.
Images to PDF: Send multiple images (JPG, PNG, WEBP) in sequence and the bot compiles them into a single PDF. Page order matches the send order.
PDF merge: Combine multiple PDF files into one. Send each PDF with the command /merge and the bot assembles them in order.
PDF split: Extract specific pages or page ranges from a PDF. Useful for sharing only relevant sections of a large document.
PDF compression: Reduce file size for easier sharing. Compression level (low, medium, high) affects quality — the bot shows size reduction before you accept.
PDF to text: Extracts all text content from a PDF as a plain text message. Works for searchable PDFs; scanned-image PDFs require OCR (see below).
OCR (Optical Character Recognition): Extracts text from scanned or image-based PDFs. Supports 50+ languages.
PDF encryption/decryption: Add password protection to a PDF or remove it (for PDFs you own).

2. @SmallpdfBot — Simplified PDF Conversion

Connected to the Smallpdf web service, @SmallpdfBot offers a streamlined experience focused on the most common conversion tasks: PDF to Word, Word to PDF, PDF to JPG, and PDF compression. It is simpler than @pdfbot but covers the 80% of tasks most users actually need.

The main advantage over @pdfbot is processing speed on large files — Smallpdf's infrastructure is optimized for high-volume conversion. For documents over 50 MB, @SmallpdfBot often completes faster.

3. @IlovepdfBot — PDF Forms and Signing

@IlovepdfBot adds capabilities beyond format conversion: PDF form filling, digital signature insertion, and watermark addition. For businesses that need to sign contracts or fill standardized forms via Telegram, this fills a gap that other PDF bots do not cover.

Best Image Converter Bots for Telegram

4. @ImageConvertBot — Universal Image Format Converter

@ImageConvertBot handles the most common image format conversions. Send any image and tell it what format you need: JPG, PNG, WEBP, GIF, BMP, TIFF, or ICO. The bot converts and returns the file in seconds.

Key use cases:

HEIC to JPG: iPhones save photos in HEIC format by default, which many Windows applications cannot open. @ImageConvertBot converts them to standard JPG.
PNG to WEBP: Reduce web image file sizes by converting PNG to the more efficient WEBP format.
JPG to PNG: Convert to PNG when you need a transparent background or lossless quality.
Any format to ICO: Create favicon files for websites from existing images.

Additional features:

Resize images (specify dimensions or percentage)
Compress JPG/PNG with adjustable quality settings
Rotate and flip images
Convert image to PDF (single-page)
Batch processing: send multiple images in a group and receive all converted files at once

5. @PhotoEditorBot — Image Editing With Conversion

@PhotoEditorBot combines basic editing with format conversion. Beyond format changes, it handles: background removal (AI-powered), filters and color adjustments, crop and resize, text and watermark overlay, and image-to-sticker conversion (crops and formats appropriately for @Stickers). Useful when you need to both edit and convert in a single workflow.

6. @RemoveBgBot — Automated Background Removal

A specialized image bot focused entirely on background removal. Send any photo and receive a PNG with the background removed (transparent). The AI works well for portraits and product photos with relatively clear subject/background distinction. Results are immediately usable for sticker creation, social media overlays, or product catalogue images.

Best Audio Converter Bots for Telegram

7. @AudioConverterBot — Audio Format Conversion

@AudioConverterBot converts between the major audio formats: MP3, OGG, WAV, FLAC, AAC, M4A, OPUS, and WMA. Telegram voice messages are encoded in OGG OPUS format — @AudioConverterBot converts them to MP3 for saving or editing outside Telegram.

Common audio conversion tasks:

Voice message to MP3: Forward any voice message to the bot with the command /convert mp3. Download the resulting MP3 to your device.
WAV to MP3: Reduce file size for uncompressed audio files before sharing.
FLAC to MP3: Convert lossless audio to a format compatible with more devices and apps.
Video to MP3: Extract the audio track from a video file and save as MP3.
Trim audio: Specify start and end timestamps to extract a clip from a longer audio file.

8. @VoiceConverterBot — Voice Message Specialist

Focused specifically on Telegram voice messages (round video notes and standard voice recordings), @VoiceConverterBot adds features @AudioConverterBot does not offer: speech-to-text transcription (50+ languages), playback speed adjustment on the output file, and noise reduction processing. Particularly useful for transcribing long voice messages in chats where you cannot listen with audio.

Best Video Converter Bots for Telegram

9. @VideoConverterBot — Video Format and Compression

@VideoConverterBot handles the most demanding file type: video. It converts between MP4, AVI, MOV, MKV, WEBM, and FLV formats and offers compression options that reduce file size without visibly degrading quality for most content.

Key features:

Convert between major video formats (MP4, AVI, MOV, MKV, WEBM, FLV)
Compress video — reduce file size by 50–80% with configurable quality settings
Trim video — extract clips by start/end time
Extract audio from video (to MP3, OGG, WAV)
Change video resolution (4K → 1080p → 720p → 480p)
Convert to Telegram-friendly formats for sending without Telegram's compression kicking in
Convert video to round video note format (512×512 px circle)

File size limits apply: Telegram bots can receive files up to 20 MB by default, with Premium users able to send up to 4 GB. For large video files, @VideoConverterBot asks you to use its web interface instead.

10. @VideoToGifBot — Video Clip to GIF

A specialized tool for converting short video clips into animated GIFs. Useful when you need a GIF for a platform that does not support video embedding. You can specify trim points before conversion, and the bot offers frame rate and resolution controls to balance GIF quality against file size.

How to Use File Converter Bots: Best Practices

File Size Limits

Standard Telegram bots have a 20 MB upload limit. Telegram Premium raises this to 4 GB for sending files, but the bot must also support receiving large files. Always check the bot's stated limits before sending large files — most bots will tell you their limit in the welcome message.

Privacy of Your Files

When you send a file to a converter bot, that file is uploaded to the bot operator's server for processing. For sensitive documents — contracts, financial records, personal identification — consider whether you are comfortable with a third party processing the file. For sensitive documents, use desktop software (LibreOffice, Handbrake, FFmpeg) where processing stays local.

Quality vs Speed

Most bots default to a balanced quality-speed setting. For maximum output quality (particularly for PDF to Word conversions and image upscaling), check if the bot offers a quality selection command. Some bots have /hq or /quality high commands that use slower but better conversion engines.

Combining Bots in a Workflow

Converter bots can be chained. Example workflow: receive a voice message from a client → forward to @VoiceConverterBot for transcription → paste transcript into a document → forward document to @pdfbot to convert to PDF → send the PDF to the client. No apps opened outside Telegram at any step.

FAQ

Are Telegram converter bots free?

Most converter bots offer free tiers with daily usage limits. @pdfbot's free tier allows a generous number of conversions per day. Premium tiers (accessed via subscription within the bot) remove limits and often add priority processing and larger file size caps. For occasional use, the free tier is sufficient for most users.

How long does conversion take?

Simple conversions (image format changes, audio format changes) typically complete in 5–15 seconds. Complex operations (PDF OCR, video compression, high-resolution image processing) can take 30–120 seconds depending on file size and server load. If a conversion takes over 3 minutes without progress, try again during off-peak hours.

Do converter bots keep my files after conversion?

Reputable converter bots delete uploaded files from their servers after a short period (typically 30 minutes to 24 hours). Check the bot's privacy policy or FAQ if data retention is a concern. File deletion policies vary by operator.

Can I convert files in a group chat or only in private chats with the bot?

Most converter bots require a private chat — you send the file directly to the bot. A few support being added to groups where users can trigger conversions with commands, but this exposes all group files to the bot, which most group admins prefer to avoid.

What if the converted file quality is poor?

For PDF to Word conversions, quality depends heavily on the source PDF. PDFs created from Word documents convert near-perfectly. Scanned PDFs (image-based) require OCR and may have minor errors. For image quality issues, try specifying a higher quality setting or a different output format. For audio/video, reduce compression aggressiveness if the output sounds or looks degraded.
