The short version

  • Each has a real cost: iLovePDF processing happens on the vendor's servers, so every file is uploaded to a third party, which rules the tools out for client documents, personal data and anything under a confidentiality obligation no matter how briefly the file is held.; Spark Mail several sync features route mail metadata and, for some features, credentials through Readdle servers, which is a materially different trust model from a local-only IMAP client.
  • They diverge on capability: iLovePDF covers Single-purpose tools, Spark Mail covers Smart Inbox.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

iLovePDF

  • Processing happens on the vendor's servers, so every file is uploaded to a third party, which rules the tools out for client documents, personal data and anything under a confidentiality obligation no matter how briefly the file is held.
  • The free tier is bounded by file size per tool rather than by feature, with Office conversions capped at 15 MB, so the large scanned documents most likely to need converting are precisely the ones most likely to be refused.
  • The conversions that require text recognition, meaning scanned PDF to Word or Excel, are held for the paid plan, and those are the conversions people genuinely struggle with, while the free ones mostly handle files that were digital already.
  • It is a per-account consumer subscription with no organisational administration, so a company that comes to depend on it ends up with staff holding personal subscriptions and no control over what is uploaded or by whom.
  • The API is a separate product with its own pricing, so a workflow prototyped by hand on the website cannot simply be automated under the same subscription and has to be costed again.

Spark Mail

  • Several sync features route mail metadata and, for some features, credentials through Readdle servers, which is a materially different trust model from a local-only IMAP client.
  • It is a client over accounts you still pay for elsewhere, so the total cost is Spark plus whatever Gmail, Outlook or Fastmail plan you already hold.
  • The free tier lacks AI Copilot and summaries, so the features it is best known for sit behind the paid plan.
  • Team features are basic next to dedicated shared-inbox tools like Front or Help Scout, so a support team scaling past a few agents will likely outgrow it.
  • Windows and Android versions have historically lagged the macOS and iOS apps in feature parity.

Answered from the vendors’ own pages

iLovePDF: Do I need an account?

Not for the basic free tools, though they are subject to per-tool size limits and restrictions on batch processing.

Spark Mail: Does Spark host my email?

No. It is a client that connects to Gmail, Outlook, iCloud or any IMAP account; you still need a mail host.

iLovePDF: Is it safe for confidential documents?

Files are uploaded to the vendor's servers for processing. For client material, personal data or regulated documents, use a tool that works locally on the machine instead.

Spark Mail: Does Spark store my email credentials on its servers?

For some features, including cross-device snooze and send-later sync, yes. It is part of how those features stay consistent across devices.

iLovePDF: What does Premium add?

Access to every tool including text-recognition conversions and PDF/A, much larger files, unlimited processing, desktop and mobile applications, digital signatures, workflows and no adverts.

Spark Mail: Is there a one-time purchase option?

No, Spark is subscription only for individuals and teams; the base client is free but AI and unlimited scheduling need Premium.

iLovePDF: Can I use it inside my own application?

Only through the separate developer API, which is priced independently, so plan the automation cost separately from the consumer subscription.
