The problem
Every "free" PDF or writing tool online eventually hits you with the same wall: a watermark, a daily limit, a forced sign-up, or a paywall right when you actually need the feature. iLovePDF wants ~$8/month. QuillBot Premium runs up to ~$20/month. Grammarly Pro is ~$12/month. Remove.bg charges per image. None of that is unreasonable for a business — but for a one-off task (convert a PDF, fix a paragraph, cut a background), it's a lot of friction.
So I built Toollium — a single site with 63 free tools that run entirely in the browser. No account, no watermark, no daily cap.
What's actually in it
The tools are grouped into a few categories:
📄 PDF conversion & utilities
PDF ↔ Word, JPG ↔ PDF, HTML to PDF, Excel to PDF, plus compress, merge, split, rotate, and unlock.
🤖 AI writing
An AI paraphraser (5 styles, no word cap — QuillBot's free tier stops at 125 words), a grammar checker powered by LanguageTool, an AI summarizer, an AI cover letter generator, and an AI email writer.
🖼️ Image tools
A background remover that runs a WebAssembly AI model client-side (remove.bg charges per image for this), plus a compressor, resizer, format converter, SVG-to-PNG, crop tool, and signature maker.
⚡ Developer utilities
JSON formatter, regex tester, UUID generator, JWT decoder, Markdown-to-HTML, text diff checker, favicon generator, password generator, and QR code generator.
💰 Finance & everyday calculators
Mortgage, debt payoff, auto loan, compound interest, rent-vs-buy, salary-to-hourly, sales tax, EMI, plus BMI and calorie calculators.
📋 CV Builder
Upload a photo, pick from 4 templates, let AI draft your summary and bullet points, export an ATS-friendly PDF.
The part I actually care about: privacy
This is the design constraint that shaped everything else — processing happens in your browser, not on a server. PDFs aren't uploaded anywhere to be converted; the background remover's AI model runs client-side via WebAssembly. Nothing is stored, so there's nothing to leak, nothing to log, and nothing to delete later.
That's also why it can stay free — there's no server-side compute cost per file, so there's no meter to run.
Why free, no catch
I'm not running a freemium funnel here — there's no paid tier waiting behind a feature flag. The honest answer is that the browser-based architecture makes marginal cost per user close to zero, so it doesn't need one.
Try it
If you try it and hit something rough — a tool that misbehaves, a format it doesn't handle, a feature you wish existed — I'd genuinely like to hear about it in the comments. This is a small, actively-worked-on project, not a finished product I'm walking away from.
