iLovePDF vs Smallpdf vs BrainyPDF — The Ultimate PDF Tool Comparison

When you need to merge, split, compress, or convert a PDF, you have three major free options: iLovePDF, Smallpdf, and BrainyPDF. Each has a different philosophy about accounts, pricing, privacy, and the free experience. This three-way comparison helps you pick the right one.

At a glance: the key differences

Smallpdf: polishes the experience but limits free users to 2 tasks per day. Requires account for full access. Files retained for a period after processing. Premium at $12/month.

iLovePDF: offers a generous free tier with hourly/daily processing caps. Requires account for full features. Files retained for a few hours after processing. Premium at ~$7/month.

BrainyPDF: zero-account, instant access with monthly (not daily) operation limits. Files deleted immediately after download. Premium at a competitive price with 100 MB file size.

Account wall — who makes you sign up?

Smallpdf requires a free account even for the limited free tier. iLovePDF nudges you toward account creation and gates some features behind login. BrainyPDF requires no account at all — open any tool and start working.

This matters because: account creation adds friction (password, email verification, yet another login to remember). Accounts mean your usage data is tied to a profile. Anonymous usage gives you more privacy and less vendor lock-in.

Free tier generosity — who gives you the most without paying?

Smallpdf free tier: 2 tasks per day with file size restrictions. This is the most limited free tier of the three. iLovePDF free tier: more generous than Smallpdf but with hourly processing caps that can interrupt workflow during heavy use. BrainyPDF free tier: 25 MB file size, monthly (not daily) operation limits. No hourly cap means you can batch-process without getting blocked.

If you process PDFs occasionally, BrainyPDF's monthly limits give you the most flexibility. If you process PDFs daily, you will hit any free tier's limits eventually and should consider premium on whichever platform you prefer.

Privacy and data handling

Smallpdf retains files for a set period after processing for quality assurance and recovery purposes. iLovePDF retains files typically for a few hours before automated deletion. BrainyPDF deletes files immediately after download with no retention period.

If you process sensitive or confidential documents, immediate deletion is the strongest privacy guarantee. BrainyPDF leads on this metric by a significant margin.

Tool coverage

All three services cover the essential PDF operations. Smallpdf has the widest feature set, including e-signatures and full PDF editing. iLovePDF covers all basics plus PDF/A conversion. BrainyPDF covers all basics plus PDF Repair and Add Page Numbers, and is actively expanding its tool set.

Pricing — what does premium cost?

Smallpdf Pro: $12/month (billed annually). iLovePDF Premium: ~$7/month (billed annually). BrainyPDF Premium: competitively priced with 100 MB file size and unlimited operations.

The verdict: which one should you choose?

Choose Smallpdf if you need advanced features like e-signatures and full PDF editing, and are willing to pay $12/month for the best-in-class feature set. Choose iLovePDF if you want a strong balance of features and affordability at $7/month, and do not mind the account requirement and hourly caps. Choose BrainyPDF if you value privacy (immediate file deletion), zero friction (no account), and monthly flexibility (no daily limits). Best for occasional users who want to get in, process a PDF, and get out — with zero commitment.
