I Tested the 5 Best Free PDF Splitters — Here's What Actually Works (2026)

ILovePDF (iLovePDF S.L., Barcelona) is one of the oldest online PDF tools, launched in 2010. Files are uploaded to their servers, split server-side, and returned as downloads. The split interface shows page thumbnails, lets you set custom ranges, or split by fixed intervals (every N pages). Paid users can queue multiple files and download results as a ZIP.

Split accuracy was flawless — every page range extracted correctly across all 30 test documents. Forms, annotations, and bookmarks survived the split intact. Speed was 3-5 seconds per document (including upload time). The thumbnail preview is clean and lets you visually select pages.

The catch: free users get 1 task per hour. That's brutal if you have multiple documents to split. The 100MB file size limit also blocked 3 of our larger scanned documents. For paid users at $7/month, these limits disappear.

SmallPDF (SmallPDF GmbH, Zurich) is known for clean, minimal design. Upload a PDF, see page thumbnails, click to select pages or set ranges, download the result. The interface is deliberately simple — fewer options than ILovePDF, but less overwhelming for casual users. All processing happens on their servers in Switzerland.

Splitting was accurate across all test documents. The UI is genuinely pleasant — the cleanest in our test. Speed was 4-6 seconds including upload. Forms and bookmarks were mostly preserved, though we noticed annotations on 2 documents lost their positioning after the split.

Free tier allows 2 tasks per day. Pro costs $12/month — the most expensive in our test. The 50MB file size limit on free is the lowest, which blocked 5 of our test documents.

Adobe Acrobat's "Organize Pages" tool lets you extract, delete, reorder, and split pages. The online version handles basic splits; the desktop app offers full page manipulation. Adobe invented the PDF format, and their splitting preserves every element perfectly — forms, signatures, annotations, JavaScript actions, multimedia embeds. If PDF fidelity matters above all else, Adobe is the reference implementation.

Split quality was perfect — every element survived the split intact, including form fields, digital signatures, and embedded multimedia. This is where Adobe's ownership of the PDF format shows. Speed was 5-8 seconds including upload. The organize pages interface is powerful but has a learning curve.

The problem: there is no free tier for splitting. The online tool requires an Adobe account and teases you with a 7-day trial, then it's $19.99/month. For a tool that splits PDFs, that's steep when free alternatives exist.

PDF24 (Geek Software GmbH, Germany) is a completely free, ad-supported PDF tool suite with 30+ tools. Files are uploaded to their German servers, split, and returned. No accounts, no usage limits, no watermarks. The trade-off is ads — banner ads between operations and on the results page. The interface is functional but dated compared to ILovePDF or SmallPDF.

Basic splitting worked reliably across all documents. Speed was competitive at 2-4 seconds. However, form field preservation was inconsistent — interactive form elements lost their functionality in 4 of our 30 test documents. Bookmark structure was partially preserved. The tool is best suited for simple documents without complex interactive elements.

The big advantage: it's genuinely free with no daily limits. No signup, no payment wall. If you can tolerate ads and don't need perfect form preservation, PDF24 gets the job done.
