How PDFWix compares
Most free PDF tools online come with hidden restrictions: daily task caps, watermarks on output, forced account creation, or file size limits. PDFWix was built to remove every one of those strings. Compared to iLovePDF, Smallpdf, and PDF24 — the three most-used free PDF platforms — PDFWix is the only option with no daily limits, no watermarks, no signup requirement, and browser-based processing for the majority of tools. iLovePDF caps free users at two tasks per day. Smallpdf requires an account after two conversions and adds watermarks on some outputs. PDF24 has no task limits but does not offer browser-only processing.
| Feature | PDFWix | Typical free PDF site |
|---|---|---|
| Free with no daily limits | Always | Limited free tasks/day |
| Watermarks on output | Never | Sometimes on free tier |
| Forced signup to download | Never | Yes for many tools |
| In-browser processing (your file stays local) | Most tools | Rarely — usually server-only |
| Server file deletion | In-memory only | Varies / unclear |
| Developer API on the same engine | Yes, pay-as-you-go | Separate enterprise plan |
| Daily task limits | None | 2 free tasks/day (iLovePDF) |
| Mobile browser support | Full | Partial on free tier |
| File size limit | Up to device RAM | 25MB on free tier |

Drop your PDF
Drag a file into the upload area or click to select. Most free PDF tools online have file size caps — PDFWix browser tools handle files up to your device's available RAM.
Processed in your browser
Twenty-two of the 24 tools run inside your browser using WebAssembly. Your file never leaves your device — no upload, no server, no privacy risk. Protect and Unlock PDF use server processing but handle files in memory only.
Download — nothing kept
Your output is ready in seconds. Browser-side jobs leave nothing behind. Server-side jobs free the file from memory the moment the download is returned to you.
Why we built PDFWix
Most "free" PDF tools online come with strings: forced signups after the second task, watermarks on every output, daily caps that push you toward a paid plan, or quietly slow processing to make an upgrade look attractive.
PDFWix was built as the answer to that. Every tool here is free, has no watermark, requires no account, and will stay that way. We don't sell your data, we don't store files our server-side tools process, and we don't add branding to anything you create. If we ever add paid features, the core free PDF tools stay free — that's the promise.
— The PDFWix Team
Your files. Your business.
- HTTPS on every upload and download — no exceptions.
- Browser-side tools never send your file anywhere. Your PDF stays on your device, full stop.
- Server-side tools (Protect, Unlock) use in-memory processing only — never written to disk, never stored after the response is returned.
- No accounts required and no tracking pixels embedded in your downloads.
- We never read, scan, index, or train AI models on your documents.
- GDPR-aligned. EU users can request data access or deletion at any time.
