Free PDF Tools Compared: iLovePDF vs Smallpdf vs PDF24 vs PDFsam
by PDFBuddyFree Research Team · Published: 4 November 2026 · Updated: 4 November 2026
Every "free PDF tool" comparison you read will give you different numbers for the same products — and that disagreement is the most honest thing about this market. Vendors change their pricing pages, some limits are described in words ("limited processing", "daily limit") rather than numbers, and reviews test on different dates. This comparison therefore does something most roundups do not: it tells you exactly what each vendor's own page publishes, flags where third-party numbers conflict, and never presents a reviewer's figure as a vendor fact. The four tools here — iLovePDF Basic, Smallpdf Free, PDF24 and PDFsam Basic — are the ones that genuinely let you complete real work without paying, and they suit very different users.
The honest summary table
| Tool | Free model | What the vendor's own page says | Best for |
|---|---|---|---|
| iLovePDF Basic | Free web tier | Limited document processing; per-tool file-size and batch limits; no desktop/mobile app | Occasional jobs, one tool at a time |
| Smallpdf Free | Free web tier | A daily download/task limit for free users (number not fixed on the page in all views) | One or two polished jobs a day |
| PDF24 Tools | Free web + free Windows desktop app | 100% free, no limits advertised; funded by advertising | Frequent free use without counting tasks |
| PDFsam Basic | Free open-source desktop | No watermarks, no limits, no uploads; split, merge, mix, rotate, extract | Sensitive files and heavy batch work offline |
iLovePDF Basic: generous, but per-tool limits
iLovePDF's free Basic plan works differently from Smallpdf's: there is no single daily task counter. Instead, its pricing page applies smaller file-size ceilings than the paid Premium plan and restricts batch processing, with the exact ceilings varying by tool — its pricing table gives per-tool figures, for example a per-file cap on PDF-to-Word conversions and a per-task file count and size cap on compression, while Premium lifts those ceilings and adds desktop and mobile apps. That structure makes iLovePDF the better free choice for a single job: you will rarely hit a task counter, but a very large file or a batch of many files will stop you. Reviews disagree on the exact per-tool numbers precisely because they differ by tool and change over time — which is why this guide does not print one number as "the iLovePDF limit". Check the live pricing page for the specific tool you need, on the day you need it.
Smallpdf Free: polished, but rationed daily
Smallpdf has the most polished interface of the four, and its free plan covers the full tool suite — compress, convert, merge, split, sign and edit. The catch is daily rationing: its pricing page describes a daily download limit for free users, and independent reads of that page in October 2026 consistently report two tasks per day. This guide reports that two-task figure as what independent reads found, not as a vendor-stated number, because the vendor page itself presents the limit qualitatively in some views. In practice, Smallpdf Free suits the occasional user — one contract to sign and one file to compress — and frustrates anyone doing daily work, because the third task waits until tomorrow or requires Pro. Note also that Smallpdf's free use runs in the browser, so files are uploaded to its servers for processing.
PDF24: the most generous free web option
PDF24 Tools, from a German company, describes its web service as 100% free thanks to advertising, with no limits advertised on its tool pages and no registration required. It also offers a free Windows desktop application, PDF24 Creator, with the same tools offline. That combination — unlimited web use plus a genuinely free desktop app — makes PDF24 the default recommendation for anyone who needs free PDF tools often and does not want to count tasks. The trade-off is advertising on the website and, for the web tools, the usual cloud caveat: your file is uploaded for processing. For non-sensitive everyday work that trade is fine; for sensitive documents, the next tool is better.
PDFsam Basic: the offline, private choice
PDFsam Basic is open-source desktop software focused on a narrower job — splitting, merging, mixing, rotating and extracting PDF pages — and it does that job without limits, watermarks or uploads. It runs on Windows, macOS and Linux, works fully offline, and never sends your file anywhere. Its scope is deliberately smaller: there is no OCR, no conversion to Office formats and no editing. But for the most common heavy task — combining dozens of files, splitting a large document, or processing sensitive paperwork — it is the tool that cannot run out, cannot watermark your output and cannot leak your document. If you install one PDF tool, install this one.
The privacy question every comparison skips
Cloud tools and local tools differ in one way that matters more than any task limit: where your file goes. iLovePDF, Smallpdf and PDF24's web tools upload your file to a server, process it there and delete it afterwards under each vendor's own retention policy. PDFsam Basic and in-browser tools never upload anything. For a restaurant menu or a school worksheet, that difference is irrelevant. For a benefit application containing your passport, bank statements and medical letters, it is decisive: prefer a tool that processes the file on your device. That is also the design of this site's own tools — PDFBuddyFree's merge, split, compress and convert tools run entirely in your browser, so your documents never leave your computer at all. Use the cloud tools for convenience; use local or in-browser tools for anything you would not email to a stranger.
How to choose in 30 seconds
- One quick job, any tool: iLovePDF Basic or Smallpdf Free — both handle it free.
- Many jobs, no counting: PDF24 web tools, or PDF24 Creator on Windows.
- Sensitive or heavy batch work: PDFsam Basic offline, or an in-browser tool that never uploads.
- Scanned documents needing OCR: none of these free tiers reliably covers it — that is a paid feature almost everywhere.
- Before you rely on any number: open the vendor's own live pricing page. Free limits change, and this guide will not pretend otherwise.
A worked example: a 40-page application pack
Imagine you must submit a benefit application pack: ten pages of bank statements, eight pages of tenancy documents, twelve pages of medical letters, and ten pages of older correspondence the portal asked for. That is 40 pages, and the choices in this guide now decide how the submission goes. If you merge all 40 pages into one file and upload it to a cloud tool, you have sent sensitive documents to a server, and if the portal's cap is 10 MB, a phone-scanned 40-page file will probably exceed it. The better path uses three steps. First, split the pack by category into four files — bank, tenancy, medical, correspondence — because the portal almost certainly has separate slots for them. Second, compress each file moderately and check every page at full zoom, rather than crushing the whole pack until the medical letterhead blurs. Third, process everything in your browser or on your desktop, so the bank statements and medical letters never leave your computer. The result is four readable, correctly sized, correctly slotted files — and a submission that a caseworker can actually decide without coming back to you.
The same logic scales down. A single-page invoice does not need any of this: any free tool handles it. The comparison in this guide matters when volume, size or sensitivity rises — and those are exactly the cases where picking the wrong free tier wastes the most time. Start from the document, not from the tool: sensitive or large means local or in-browser; occasional and ordinary means any free tier; daily and heavy means PDF24 or PDFsam Basic, because a daily counter will stop you mid-week.

Frequently asked questions
Which free PDF tool has no daily limit?
PDF24's web tools advertise no limits, funded by advertising, and PDFsam Basic is free open-source desktop software with no usage limits. Both are the honest answers when you need to process many files without hitting a daily counter.
What is the Smallpdf free plan limit?
Smallpdf's free plan is rationed daily: its pricing page describes a daily download and task limit for free users. Independent reads of that pricing page in October 2026 report two tasks per day, but the vendor page itself does not publish one fixed number in all views, so check the live pricing page before relying on a number.
What is the iLovePDF Basic free plan limit?
iLovePDF Basic has no single daily task counter. Instead its pricing page lists per-tool limits: smaller file-size ceilings than the paid plans, limited batch processing, and no desktop or mobile app access. The exact ceilings differ by tool, so check the live pricing page for the tool you need.
Is PDFsam Basic really free forever?
Yes. PDFsam Basic is open-source desktop software for splitting, merging, mixing, rotating and extracting PDF pages. It runs on Windows, macOS and Linux, adds no watermark, and processes files locally on your computer, so your documents are never uploaded.
Are free online PDF tools safe for sensitive documents?
Cloud tools upload your file to their servers and delete it after processing, under each vendor's own retention policy. For sensitive documents such as benefit applications, passports or bank statements, prefer a tool that processes files in your browser or on your computer, so the file never leaves your device.
Do free PDF tools add watermarks?
The four tools in this comparison do not watermark standard free output. Watermarks normally appear on trial versions of paid desktop suites or on some OCR and editing features that are paywalled, not on basic free merging, splitting or compressing.
Why do free limits differ between reviews?
Because vendors change their pricing pages and because some limits are described qualitatively (limited processing, daily limit) rather than as one number. Reviews also test at different dates. The only reliable check is the vendor's own live pricing page on the day you need the tool.
When should I pay for a PDF tool?
Pay when your volume or file sizes regularly exceed the free ceilings, when you need OCR on scanned documents, batch processing, or desktop and mobile apps. For occasional merging, splitting, compressing and converting, the free plans in this guide are enough.
