The short answer
Every major PDF splitter does the same basic job — break one PDF into individual pages or page ranges — so the real differences are in free-tier limits, not capability. iLovePDF and Smallpdf both cap free use (iLovePDF by per-tool file size, Smallpdf at 2 tasks/day), Adobe Acrobat's split tool sits behind its $12.99/mo Acrobat subscription after a short trial, and PDF24 is free desktop software with no account or task cap. All four upload your file to a server to do it. If you just need to split a PDF without hitting a daily counter or an upload step, a browser-based tool that runs the split locally is worth trying first.
iLovePDF and Smallpdf
Both are cloud-based suites with a split tool included in their roughly 30-tool catalog. Smallpdf's free plan is capped at 2 tasks per day shared across every tool — split one file and merge another, and the daily allowance is gone. iLovePDF doesn't publish one flat daily number; instead it applies per-tool file-size ceilings and disables batch processing on the free "Basic" plan. On price, iLovePDF's Premium tier ($9/month, about $5/month billed annually) has come in at or below Smallpdf's Pro plan on every billing cycle we checked directly against both pricing pages. Neither service processes your file locally — it's uploaded, split on their servers, and the pieces are made available to download.
Adobe Acrobat and PDF24
Adobe Acrobat's online split tool is free to try but the split-PDF feature itself sits behind an Acrobat subscription (from $12.99/month after a 7-day trial) once the trial period ends — the most expensive of the four for occasional use. PDF24 sits at the other end: a free Windows desktop app (not browser-based) with no daily task limit, no account, and no subscription, built around a suite of PDF utilities including split, merge, and compress. Its tradeoff is that it's installed software, not a web tool, and Mac/Linux users are largely left out — PDF24's browser tools exist but are more limited than the desktop app.
A note on the upload step itself
All four options above have one thing in common: your PDF leaves your device to get split, whether that's an upload to a server or handing it to installed desktop software. PixelTools' [split-pdf tool](/split-pdf) processes the file entirely in your browser using pdf-lib — no upload, no daily task counter, no account. One concrete tradeoff worth knowing: because it builds each split piece as a fresh PDF document and copies pages into it, it doesn't carry over the original file's bookmarks or outline tree into the split pieces — a limitation client-side PDF tools built the same way generally share, not something unique to one product. For a PDF with no bookmarks (the common case), this doesn't matter at all.
Which one should you use?
For occasional splitting with no cost, PDF24 (desktop, Windows) or a browser-based tool avoids both the daily-task ceiling and the upload step. If you need iLovePDF or Smallpdf's broader tool catalog anyway, their split tool is a reasonable add-on rather than a reason to choose one service on its own. Adobe Acrobat only makes sense if you already need Acrobat for other reasons — paying $12.99/month just to split PDFs is the expensive option here. If your PDF has bookmarks you need preserved in every split piece, check that explicitly before relying on any client-side splitter, ours included.
