ONLYOFFICE vs PDF Bot • Free Converter
For anyone who works with office files, ONLYOFFICE (@ONLYOFFICE_bot) is the stronger choice: it creates, edits and converts DOCX, XLSX and PPTX files inside Telegram and gives colleagues a co-editing link that works for 24 hours. It is free, comes from the company behind the ONLYOFFICE suite, and its code is public on GitHub. PDF Bot (@pdf_bot) is a simpler utility: it turns images into a PDF and PDF pages back into images, but merging, splitting and OCR are not confirmed and its file limits are not published. Choose PDF Bot when all you need is to turn phone photos or screenshots of pages into one PDF to send or print.
