Frequently Asked Questions

Do I need an account to use Convert.FAST?

No. You can start converting files immediately with no sign-up required. Anonymous guests and free accounts share the same conversion limits. The difference is:

  • Guests get a shared daily allowance per IP address.
  • Free accounts get their own daily credits and email support.

Pay as you go credits and Pro subscriptions unlock Pro limits and use paid balances only.

How do credits work for batch conversions?

Each file in a batch costs credits individually based on its size or page count. Batch limits vary by tier: Free (50 files), Pro (1000 files).

Why do some conversions cost more credits than others?

Most image and document conversions cost 1 credit per 5 MB of input. Multi-output conversions like PDF to JPG—where one PDF creates many images—cost 1 credit per 5 pages instead. Conversions requiring more raw processing time cost more: AVIF encoding costs 4 credits due to its computational intensity. See the limits table above for exact costs per converter.

What happens if my conversion fails?

You won't be charged for failed conversions. Credits are debited when processing starts, but our automatic refund system quickly returns credits for any job that fails due to corruption, unsupported features, or other issues.

How long are my converted files available?

All converted files are automatically deleted after 1 hour for security and privacy. You can also manually delete files immediately after downloading. Read our security policy →

Can I convert documents with sensitive content?

Yes. Most processing happens on EU-only servers we control. AI-powered features (like audio transcription) use vetted GDPR-compliant providers. Files are encrypted with AES-256 at rest and never used for AI training. Learn more about our processing →
