LightConv vs Convertio

A long-standing online file conversion service that supports hundreds of format pairs across documents, images, audio, video and ebook formats.

This page lays out what Convertio (founded 2014, freemium with paid tiers, ads on the free tier, conversions happen on convertio's servers.) does that LightConv doesn't, and what LightConv does that Convertio doesn't. Both tools exist for a reason — the right pick depends on what you're converting and where the file should be allowed to go.

Convertio's primary audience: People searching for niche format conversions (rare RAW formats, ebook conversions, audio/video transcoding) who don't have specialised software installed.

Convertio is the better pick if

  • You need to convert audio or video formats (MP3/MP4/WAV/FLAC etc.) — LightConv doesn't ship media codecs
  • You need PDF conversion, OCR, or document format conversions (DOCX, EPUB, PPT, XLSX)
  • You need camera RAW conversion (CR2/CR3/NEF/ARW/DNG) — these require libraw which we haven't shipped yet
  • You want a cloud-storage integration for batch conversion

LightConv is the better pick if

  • You're converting HEIC, PNG, JPG, WEBP, AVIF or other common image formats — and you care that the file stays on your machine
  • You're working with CSV, JSON, YAML, JWT, Base64 or similar developer tools
  • The file contains anything sensitive (medical scans, IDs, contracts) that has no business sitting on a third-party server
  • You want to see exact performance numbers (ms + MB/s) per conversion

Convertio's strengths — credit where due

  • Hundreds of supported formats including audio, video, ebooks, fonts, presentations and CAD drawings — far more breadth than LightConv has
  • Cross-document conversions (DOCX → PDF, EPUB → MOBI, MP4 → MP3) that genuinely require server-side software
  • Cloud integrations with Google Drive, Dropbox, OneDrive — you can convert files without downloading them locally first
  • 11+ years of brand recognition and SEO authority

Where LightConv has the structural edge

  • Files never leave your browser — Convertio uploads everything to their servers in the EU/US
  • Conversion shows real-time ms and MB/s — you can see exactly how fast it is
  • No ads, no signup, no upload limit per session, no waiting in a queue
  • Works offline as an installable PWA after the first visit
  • Open about what we don't do (RAW, PDF) instead of failing silently when the upload errors

If LightConv sounds like the right pick for your use case, start at the homepage — every tool is on one page and the conversion happens before you finish reading the card.
