Pricing
The structural difference: Converterer bills a flat rate per conversion, while CloudConvert meters conversion minutes, where a long video consumes several credits and document/PDF conversions carry 2–4× credit multipliers.
| Monthly volume | Converterer | CloudConvert |
|---|---|---|
| 1,000 / month | $0 (Free plan) | Roughly $8–9/month on a 1,000-credit subscription |
| 10,000 / month | $29.99 (Growth) | Roughly $80–90/month at published per-credit rates |
| 50,000 / month | $99.99 (Scale) | Roughly $400+/month before volume discounts |
CloudConvert figures are approximate: they assume 1 conversion ≈ 1 credit (a sub-1-minute job with no multiplier) and per-credit rates of roughly $0.008–0.017 as of June 2026. CloudConvert sets exact prices in an interactive slider, so check cloudconvert.com/pricing for current numbers. Converterer overage: $0.02–0.03 per extra conversion depending on plan.

Migration
Most CloudConvert integrations collapse into a single request on Converterer: swap the Bearer token for HTTP Basic auth with your API key, and replace the import → convert → export job chain with one multipart POST. Webhooks re-register in the dashboard, and output lands straight in your own bucket.
# CloudConvert: create job → upload via import task → poll → export task # Converterer: one request, then a webhook (or fetch from your bucket) curl -u "$CONVERTERER_API_KEY:" \ https://api.converterer.com/convert \ -F input=@report.docx \ -F output_format=pdf # → {"id":"9f1a8e7c-…", "status":"queued"} - result lands in your storage
