Best Tool to Split PDF Files in 2026: 8 Tools Compared

iLovePDF is the easiest starting point for a one-off split. Upload a PDF, choose custom ranges or split every page, preview the pages, and download the results. The interface is clear enough that a first-time user can finish a split in minutes, and the same site covers merging, compressing, and converting.

The limits are the usual online trade-offs. Free processing is capped, and files must be uploaded, which makes it a poor choice for sensitive contracts or medical records. For ordinary documents such as course handouts, reports, and forms, iLovePDF is our pick for speed and simplicity.

Smallpdf suits users who want a clean, guided split without extra options getting in the way. You can extract selected pages or split a document manually, then download the new files. The design is consistent across desktop and mobile browsers, which helps when a split is needed away from a main computer.

Free use is limited, so frequent users will hit a daily cap. That makes Smallpdf better for occasional jobs than for a daily workflow. If you split PDFs a few times a month and value a tidy interface, it is a solid choice.

Adobe Acrobat is the heavy-duty option. The desktop app can split by page count, file size, or bookmarks, and it handles large, complex PDFs more reliably than most browser tools. For professionals who already use Acrobat for editing, signing, and form work, splitting is one feature inside a complete toolkit.

Cost is the barrier. The full app needs a subscription, and the free online tools cover only limited jobs. Users who only split a PDF occasionally should start with a free tool. Users who work with PDFs daily, or who need dependable results on large files, will find Acrobat worth the price.

PDF24 Tools stands out because its online tools are published as free without the tight daily caps found elsewhere. Splitting by page works in the browser, and Windows users can also install PDF24 Creator for offline work. That combination covers both a quick browser job and a regular desktop workflow.

The desktop app is Windows only, so Mac and Linux users are limited to the online tools. The design is also more functional than polished. For users who want a free tool they can return to often, without counting daily tasks, PDF24 is a strong pick.

Sejda is for users who need more control than a simple page split. It can split by page ranges, every page, bookmarks, file size, and even text found in the document. That range helps with reports split by chapter, invoices split by section, and long documents that need a logical break rather than an arbitrary page count.

Free online use is capped by tasks per hour and file size, so it suits occasional precise jobs rather than bulk work. A desktop option exists for users who want to avoid some online limits. For a tricky split that other tools cannot express, Sejda is the tool we would try next.

PDFsam Basic is our pick for sensitive files. It is free, open source, and runs on your computer, so a confidential PDF never needs to be uploaded to a website. Splitting options include page ranges, every set number of pages, bookmarks, and target file size, which covers most structured jobs.

The trade-off is convenience. You must install it, and the interface is plain compared with browser tools. For legal, medical, financial, or HR documents, that trade is worth it. If privacy matters more than speed, start here.

PDFgear offers a free desktop PDF toolkit that includes splitting, along with editing, converting, and annotation. That breadth helps users who split PDFs as part of larger document work, such as preparing handouts, forms, or reports. The apps run on major desktop and mobile platforms, so a split started on one device can be finished on another.

It is less of a pure online splitter than iLovePDF or PDF24, so users who want a quick browser job may prefer those. For users who want a free desktop app that does more than splitting, PDFgear is a practical choice.

Lumin suits users who split a PDF and then need to edit, annotate, or share it. The split tool sits inside a broader editor, so a document can be divided, marked up, and sent onward without switching apps. That workflow helps teachers, reviewers, and small teams who handle documents together.

Users who only need splitting may find Lumin more than they need, and some features sit behind paid plans. For document work where splitting is the first step, not the whole job, Lumin keeps the workflow in one place.
