The free CloudConvert & Zamzar alternative
ZeroPhantom is a free online file converter supporting 200+ format pairs — convert PDF to Word (DOCX), JPG to PDF, PNG to JPG, HTML to PDF, CSV to Excel, DOCX to TXT and more, instantly in your browser with no account required. Unlike CloudConvert or Zamzar, free conversions have no daily limits and files are auto-deleted immediately after download.
Need an email warmup service? ZeroPhantom's SMTP warmup starts at $9/month — a fraction of Lemwarm ($29/mo) or Mailwarm ($15/mo). Gradual ramp-up, multi-account support, and a real-time dashboard are all included.
The disposable temp email generator creates throwaway inboxes instantly — no registration, auto-refreshes every 30 seconds, and works as a Mailinator or Guerrilla Mail alternative. The free OCR tool (powered by Tesseract) extracts text from JPG, PNG, PDF and TIFF files in over 100 languages.
For developers, the REST API gives programmatic access to all converters and OCR at $0.0002 per call. Temp Mail API is always free — orders of magnitude cheaper than competing services. Credits are purchased once and never expire. Get started from $5 →
