100 credits/month, charged only on success | #### the literal three clicks - **Open** [500toolbox.com](https://www.500toolbox.com/) — or add the [Chrome extension](https://www.500toolbox.com/extension) for the offline popup - **Drop your file** on the tool — search everything with `Ctrl+K` from any page - **Download the result** — the file was processed in your session, not on a server Most tools never touch a server at all — your browser does the work. > **the rare gems · the free-forever stack · the limits + unlocks** > > **💎 Rare gems** > > - 🧩 **The popup is a developer rescue kit** — JWT expiry decoder, regex tester, hash generator, CSV↔JSON, cron explainer, font/colour/page forensics, auto-refresh, screen recorder — 50 tools that never ask where you’ve been > - 📚 **Curated packs** — [Student (20)](https://www.500toolbox.com/packs), Creator (17), Freelancer (32) — a starting shelf instead of 599 choices > - 📄 **The workflow king stays** — [DamnPDFs](https://damnpdfs.com/) (71 tools, the original core of this find) has a [workflow builder](https://damnpdfs.com/tool/workflow): scan → OCR → split-by-text → redact → watermark → sign, chained once, replayed on every file > - 🕵 **PDFMergely** — [68 browser PDF tools](https://pdfmergely.com/) with on-device AI Q&A and a live **“0 bytes uploaded” counter** you can watch while you work > - 🧾 **The life-admin chain** — build the invoice or resume in DamnPDFs → clean the QR/size in 500Toolbox → redact → sign → SHA-256 fingerprint so the recipient can prove the file never changed > - 🧰 **totakit (wildcard)** — [700+ on-device tools](https://totakit.com/) with an open-source SDK/CLI/MCP server so AI agents run file ops locally (its PDF shelf is thin — that’s why it’s the wildcard, not the core) > > **🖥 When free-online isn’t enough** > > - **Windows + fully offline** → [PDF24 Creator](https://tools.pdf24.org/en/creator) — unrestricted desktop suite, files never leave the PC > - **Exotic formats** → [ConvertX](https://github.com/C4illin/ConvertX) self-hosted — 1,000+ format combos via FFmpeg/LibreOffice/Calibre > - **Your own PDF server** → [Stirling-PDF](https://github.com/Stirling-Tools/Stirling-PDF) (96k​⭐) — pipelines, API, local AI > > **⚠ Limits, plainly** > > - server-backed tools have daily limits; huge files can exhaust browser memory (split first — there’s a split-by-size tool for that) > - OCR is on-device Tesseract, capped at 15 MB / 15 pages — split long scans, work at ~300 DPI, proofread names and amounts > - 500Toolbox is closed-source (Hami Tech) — test with non-sensitive files first; the inspectable escapes are totakit, ConvertX and Stirling-PDF > - browser e-sign ≠ a certificate-based digital signature — check what the recipient requires > - “free forever” is a promise, not a contract — keep a local fallback (that’s what PDF24 is for) > > **🔓 The unlocks** > > - **Daily limit hit?** → the same job usually exists as a client-side tool — route work to the browser-local ones first > - **Need it offline?** → extension popup works with no connection; DamnPDFs and PDFMergely cache for offline after first load; hard-offline → PDF24 Creator > - **AI keeps guessing?** → paste the [MCP server URL](https://www.500toolbox.com/api/mcp) into Claude/Cursor/VS Code — it answers from real tool output, not vibes Five hundred ninety-nine reasons to never install a “free trial” again.
