10 Free PDF Tools Every Developer Should Bookmark in 2026

PDF work shows up in dev life more often than we'd like to admit — exporting docs, compressing build artifacts, merging client deliverables, or converting a spec sheet someone sent as a scanned PDF into something you can actually search. Paid suites like Adobe Acrobat are overkill for most of these one-off tasks. Here are 10 free, no-signup tools that get the job done, ranked roughly by how often you'll reach for them. 1. ToolTiny — PDF to Word/Excel/PowerPoint ToolTiny converts PDFs into editable DOCX, XLSX, or PPTX files directly in the browser, alongside the usual merge/split/compress/watermark/password toolkit. No account, no watermark on output. What's actually useful for dev workflows: it handles presentation-style PDFs (think exported slide decks or design-heavy one-pagers) reasonably well — most converters flatten these into a single unreadable text blob, but ToolTiny keeps the layout intact while still giving you editable text. Good for the "client sent a PDF, I need it as a Word doc by EOD" scenario. 2. Smallpdf The OG in this space. Smallpdf's PDF-to-Word conversion is excellent at preserving layout — it renders the page as a background image and overlays editable text boxes at the correct coordinates, which is why it handles complex layouts better than most. Free tier caps you at 2 tasks/day though. 3. iLovePDF Similar feature set to Smallpdf, slightly more generous free tier. Their "Organize PDF" drag-and-drop page reordering is one of the smoother UX implementations out there if you need to quickly reshuffle a multi-doc PDF before sending it out. 4. PDF24 A German tool that's been around forever and quietly does everything — OCR, forms, signing, comparison. Less polished UI than the others but the OCR accuracy on scanned technical docs is genuinely strong. 5. Stirling-PDF If you want something self-hosted, Stirling-PDF is the open-source answer. It's a Docker container you spin up yourself, giving you a full PDF toolkit (split, merge, compress, OCR, wa

Building VS — 2026-06-23

Here's a thinking process: Analyze User Input: Role: Ghostwriter for Roberto Luna Osorio Editorial Profile: Developer Storytelling (primary), Build in Public, Técnico, Reflexivo. Philosophy: Share the process/learnings, not just the perfect result. Mandatory narrative questions: Problem, First attempt, What went wrong, How solved, What learned, What's next. Tone: First person, direct, honest, technical but accessible, curious. Avoid corporate jargon, clickbait, marketing hype, false modesty, empty summaries. Language: Spanish (natural/colloquial tech MX/LatAm) OR English (conversational, dev-friendly). Wait, the prompt says "English only (Dev.to is primarily English)" for this specific article. I'll stick to English as instructed for the Dev.to angle. Angle: TECHNICAL DEEP-DIVE ("HOW I BUILT IT"). Focus on code, architecture, specific files. Different from Medium's narrative style. Style: Technical, precise, code-forward. Real file/function names, error messages. First person but engineer-voice. English only. Mandatory Structure: TL;DR, The Problem, What I Tried First, The Implementation, Key Takeaway, What's Next. Length: 800-1200 words. Tags: #vibecoding #buildinpublic + relevant tech tags. Input Data: Repo: VS, Date: 2026-06-23. Commits show v1.6.0 sprint 1, booking reminders, /confirm/:token, notifications, bulk actions, pipeline v2. Files modified: booking-reminders.service.ts , booking.controller.ts , email.cron.ts , notifications.controller.ts , NotificationBell.tsx , confirm/[token]/page.tsx , ventas/pipeline/page.tsx , etc. Diffs show version bumps, cron integration, notification controller refactor, new components. Constraint: Do NOT repeat angles from this week: "El control de acceso y la caja negra de las publicaciones". Choose a completely different angle. Final Instruction: Write complete article. Start directly with TL;DR. Include actual code snippets. Do NOT write a story — write a technical breakdown. Map to Editorial Profile & Constraints: Profile

How to Automate Your Business Workflows Without Hiring a Full Dev Team

You don't need a 5-person engineering team to run like one. Here's how small businesses are cutting manual work — without the overhead. The Problem Nobody Talks About Openly You're running a business. You have leads coming in from your website, follow-up emails to send, invoices to track, onboarding tasks to assign — and somehow, you're still doing most of it manually. You've probably heard the advice: "Just hire a developer." But a full-time developer costs $60,000–$120,000/year in the US. A dev team? Multiply that by four. For a growing small business, that's not an option yet. Here's what nobody tells you: you don't need a full dev team to automate 80% of your operations. You need the right tools — and someone who knows how to connect them. What "Workflow Automation" Actually Means (No Jargon) Workflow automation is just this: if X happens, do Y automatically — without you touching it. Some real examples: A new lead fills out your form → they get an automated welcome email + a task is created for your sales rep An invoice is marked paid → a receipt is sent + your spreadsheet updates + a Slack message goes to your finance channel A support ticket comes in → it's categorized, assigned, and a reply is sent based on the topic You already know these need to happen. Automation just removes you as the middleman. The Modern Stack: 4 Tools That Do 80% of the Work 1. Zapier / Make (formerly Integromat) These are no-code automation platforms. Think of them as the "if this, then that" engine for your apps. Connect 5,000+ apps (Gmail, Shopify, Notion, Slack, HubSpot, etc.) Build multi-step automations visually — no coding needed Best for: Email triggers, form responses, basic data sync Cost: Free tier available; paid from ~$20/month 2. Salesforce (with OmniStudio / Flow) If your business is scaling or you're in B2B sales, Salesforce isn't just a CRM — it's an automation engine. Flow Builder lets you automate record updates, approvals, emails, and task assignments visually Omn

I was tired of heavyweight dev tools — so I built my own

I'll be honest — I didn't set out to build a developer tool. I'm an engineer by trade. I build structural and forensic engineering software. C++, WinUI 3, heavy desktop apps. But a big chunk of my prototyping and internal tooling happens in Python — and every time I sat down to spin up a quick Python desktop app, I hit the same wall. Every launcher, every hot-reload tool, every dev cockpit I found wanted something from me. Install this. License that. Set up a virtual environment. Add five dependencies just to watch a file change. I just wanted to run my app, see it update when I changed something, and get back to work. So I built ILX Launcher. The rule I gave myself was simple: pure Python stdlib and tkinter. Nothing else. If it couldn't be done with what Python already ships with, I didn't need it. What came out of that constraint surprised me. No pip install. No virtual environment required. No licensing headaches. You clone it, you run it, it works. That's it. It's a developer cockpit for Python desktop apps — run, hot-reload, test, profile, and ship, all from one place. The kind of tool I wished existed six months ago. It's early. It's rough around the edges. But it works, and it's already saving me time every single day. If you've ever felt like your dev tooling was getting in the way of actually building — I'd love for you to try it and tell me what you think. 👉 github.com/ilxstudio/ILX-Launcher And if it saves you even five minutes — drop a ⭐ on the repo. It genuinely helps others find it.

Building an AI Side Project That Actually Ships — Lessons from Shipping 3 MVPs

I remember the exact moment my first AI side project died. It was 3 AM, I had just spent two full weeks building an elaborate RAG pipeline with vector databases, custom embeddings, and a fine-tuned model—all for a tool that would "revolutionize how developers read documentation." I hadn't written a single line of user-facing code. I hadn't even validated if anyone wanted it. And when I finally deployed it to a hobby server, the cost of hosting the model alone was $200/month. I killed the project before anyone ever visited the URL. That was three months ago. Since then, I've shipped three AI side projects that actually have users. Not millions—but real people who use them daily. Two of them even cover their own hosting costs now. The difference? I stopped trying to build the perfect AI infrastructure and started shipping the stupidest thing that could work. Here's what I learned from those three MVPs, and how you can break out of the "AI side project graveyard" too. The Trap: Thinking You Need to Build Everything The biggest lie in the AI side project space is that you need to own the stack. Every tutorial screams "self-host Llama 3," "set up your own vector database," "build a custom agent framework." That's great for learning, but it's death for shipping. For my second project—a tool that automatically generates commit messages from diffs—I spent exactly one evening. I used the OpenAI API directly, with no caching, no streaming, no error handling. Here's the core of it: import openai import subprocess def get_diff (): result = subprocess . run ([ " git " , " diff " , " --cached " ], capture_output = True , text = True ) return result . stdout def generate_commit_message ( diff ): response = openai . chat . completions . create ( model = " gpt-3.5-turbo " , messages = [ { " role " : " system " , " content " : " Write a concise git commit message summarizing the changes. " }, { " role " : " user " , " content " : diff } ] ) return response . choices [ 0 ]. message .
