Two giants and one outsider: iLovePDF (the most generous free tier) and Smallpdf (the strongest brand, the strictest free wall) both process your documents on their servers — while PDFBuddyFree runs every tool entirely in your browser and never receives your file at all. This is an honest comparison: where each free plan stops, what each paid plan costs, and where we will tell you to pick one of the giants instead of us.

🔒 Files never leave your browser. Zero upload. GDPR-friendly.

A note on bias: we make PDFBuddyFree, one of the three tools compared here. We have tried to be straight about where the other two are the better choice, and the comparison table below includes an honest "where we lose" row. Every figure about iLovePDF and Smallpdf comes from their published free tiers as reported by independent comparisons in 2026, not from their marketing copy.
| Smallpdf | iLovePDF | PDFBuddyFree | |
|---|---|---|---|
| Free tier | ~2 tasks per day, resets daily | Free tier with per-task file size caps (around 100 MB for conversions) | No task limits, no signup, no account |
| Paid plan | Pro ~$15/month (about $108/year) | Premium ~$4–$9/month depending on term | Free — no paid plan exists |
| Where your file goes | Uploaded to their servers (Ireland) | Uploaded to their servers (EEA as a rule) | Stays in your browser — never uploaded |
| Deleted after | About 1 hour | Within about 2 hours | Never leaves your device — nothing to delete |
| OCR (scanned → searchable) | Paid tier | Premium | Not available |
| Edit existing PDF text | Paid tier | Premium | Not available |
| Desktop / mobile apps | Web, Windows, iOS, Android, Chrome extension | Web, Windows, macOS, iOS, Android | Browser only |
| Developer API | No public API | Yes — iLoveAPI | No |
| Best for | Occasional users who want a polished interface | Frequent free users; developers via API | Privacy-sensitive documents; unlimited quick tasks |
Smallpdf's free tier is the strictest of the three: about 2 tasks per day, resetting daily. Compress one PDF in the morning and merge another at lunch and you are done until tomorrow — or on the Pro page. It is a deliberate funnel, and it works: Smallpdf is a huge, profitable company. If you genuinely use PDF tools once a week, the free tier is fine; if you use them daily, budget for Pro (~$15/month).
iLovePDF is the more generous free option for one-off work: instead of a hard daily task count, the free tier caps per-task file sizes (independent comparisons put conversion caps around 100 MB). That means three quick merges in a day usually work where Smallpdf would stop you. Premium (~$4–$9/month depending on term) unlocks OCR, true text editing, and higher limits. For heavy free users, iLovePDF is usually the better giant.
PDFBuddyFree has no wall at all because there is nothing to ration: no servers process your files, so there is no server capacity to meter. Unlimited tasks, no signup, no daily reset. The trade-off is scope (see below) — but for the tasks we do cover, the free tier is the whole product.
This is the row that matters most and the one most comparisons bury. Both giants upload your document to their servers before processing it — that is how their architecture works, and their privacy policies describe deletion windows to handle it: Smallpdf deletes after about an hour (servers in Ireland), iLovePDF within about two hours (EEA servers as a rule). These are reputable companies with GDPR paperwork. But the file still travels to, sits on, and is processed by infrastructure you did not choose, for a window you do not control.
PDFBuddyFree is architecturally different: your file never leaves your device. The tools run as JavaScript in your browser tab — the same pdf-lib and pdf.js libraries developers use, loaded from a CDN — and the processed file is generated locally and downloaded straight to you. There is no upload, no server copy, no retention window, no account tying your identity to the document. You do not have to trust a policy; you can verify it: open your browser's Network tab during any tool, and you will not see a single byte of your document uploaded.
When does this actually matter? For the documents people process most: contracts, IDs, payslips, medical records, bank statements, legal productions. "Deleted after an hour" is a promise about someone else's server. "Never uploaded" is a property of the architecture. For confidential documents, architecture beats policy.
Honesty requires the other side of the ledger. PDFBuddyFree does not offer OCR, true in-place text editing, desktop or mobile apps, cloud storage integrations, batch automation, or a developer API. If you need to make a scanned PDF searchable, iLovePDF Premium or Adobe Acrobat are the honest recommendations — we will not pretend a browser tool replaces them. If your whole team lives in Google Drive and needs one-click workflows, Smallpdf's integrations are genuinely useful. We are a set of focused, unlimited, private tools; the giants are full platforms. Pick the platform when you need the platform.
What we do cover — merge, split, compress, rotate, deskew, redact, remove metadata, Bates stamping, signatures, watermarks and more — we do with no limits, no signup, and no upload. For those tasks, there is no reason to hand your document to a server.
iLovePDF has a free tier with per-task file size limits (around 100 MB reported for conversions). Beyond that you need Premium, which runs roughly $4–$9 a month depending on the billing term. The free tier is generous for occasional one-off tasks, but regular users hit the walls quickly.
Smallpdf's free tier allows about 2 tasks per day, resetting daily. Pro costs around $15 a month (about $108 a year). If you only compress one PDF a day it works; anything more and you are on the subscription page by lunchtime.
For free one-off use, iLovePDF is usually the more generous option (file size caps rather than a hard daily task count). Smallpdf has the stronger brand and cleaner interface but the stricter 2-tasks-a-day wall. For privacy, neither beats a browser-only tool: both upload your file to their servers — Smallpdf deletes after about an hour, iLovePDF within about two.
Yes — both process your documents on their infrastructure. Smallpdf's servers are in Ireland and it deletes files after about an hour; iLovePDF uses EEA servers as a rule and deletes within about two hours, per independent comparisons. If you handle contracts, IDs, or financial documents, a browser-only tool that never uploads the file is the safer architecture.
Honestly: quite a lot. We do not offer OCR, true text editing of existing PDFs, desktop or mobile apps, cloud storage integrations, batch automation, or a developer API. The giants are full platforms; we are a set of focused tools that run entirely in your browser. If you need OCR or editing, iLovePDF's Premium or Adobe Acrobat are the honest recommendations.
The one that never receives your document. iLovePDF and Smallpdf are reputable companies with published deletion policies (1–2 hours), but the file still travels to and sits on their servers in the meantime. A browser-only tool processes the file on your own device — there is no upload, no server copy, and no retention window to trust. You can verify it in the browser's network tab.
