PDF24 is one of the most capable free PDF platforms — unlimited tasks, no account needed, and a Windows desktop app for offline processing. The main reason people look for PDF24 alternatives is the interface: it is dense, text-heavy, and functional rather than user-friendly, which makes mobile use particularly difficult. If you want the same range of PDF tasks but in a cleaner, faster-loading interface that works well on any device, there are several alternatives worth comparing.
No signup required
You should be able to use any tool without creating an account.
No watermarks
Free tools shouldn't stamp your output with their branding.
Client-side privacy
The best tools process your file in the browser — nothing uploaded.
No arbitrary file limits
Daily caps and tiny file size limits are artificial restrictions.
Fast processing
Browser-native tools have no server queue — results are instant.

iLovePDF has a much cleaner layout than PDF24 — easier to navigate on both desktop and mobile — while maintaining a similarly broad tool set. It covers 25+ PDF operations with no daily usage cap on the free tier, making it one of the better direct alternatives for PDF24 users frustrated with the interface. The downsides are the advertising in the free version and the fact that all processing happens on iLovePDF's servers. For users who work with sensitive documents, this is a consideration. Overall iLovePDF sits in a good middle ground between usability and feature breadth.
Pros
Cons
If PDF24's main problem for you is the cluttered interface, Smallpdf is the cleanest alternative available. Its design is minimal and purpose-built, loading quickly and working well on any screen size. The tool set covers the essentials reliably. The compromise is the free tier limit of two tasks per day, which significantly restricts regular use. For someone who only occasionally needs a PDF tool, Smallpdf's experience quality makes the limit acceptable. For heavier users, the paywall becomes a recurring frustration.
Pros
Cons
Criply addresses PDF24's interface issue directly — it is clean, fast, and designed for mobile from the ground up. Core PDF operations (compress, merge, split, rotate, convert) run entirely in the browser, so files never reach a server. There is no daily limit, no signup, and no advertising. The trade-off compared to PDF24 is a smaller total feature set — no OCR or PDF form tools yet. For the tasks it covers, Criply is faster and more pleasant to use on any device, and there is an embeddable widget at criply.co/embed if you want to add tools to your own site.
Pros
Cons
Criply's PDF and image tools process your files directly in the browser. No account needed, no daily caps, no watermarks — and an embeddable widget at criply.co/embed if you want to add tools to your own site.
