Why browser-based?

Every other "online tool" site uploads your PDFs and images to their server for processing. That means:

Your sensitive documents sit on someone else's machine

Processing speed depends on their server load

File size limits, watermarks, or forced signups

I built everything using client-side processing — Canvas API, pdf-lib, Tesseract.js (WebAssembly), and more. Your files literally never leave your device.

What's included

PDF Tools (28): Merge, split, compress, convert to Word/Excel, password protect, watermark, page numbers, metadata editor

Image Tools (30): Compressor, background remover, crop, resize, DPI changer, EXIF viewer/remover, OCR (image to text), meme generator, QR code generator

Developer Tools (42): JSON formatter, JWT decoder, Base64/Base32 encoder, regex tester, cron generator, SQL formatter, CSS/JS/HTML minifier

Design Tools (14): CSS gradient, box shadow, border radius generators, color contrast checker (WCAG), Tailwind component builders

Calculators (16): EMI, SIP, BMI, compound interest, salary tax, GST/VAT, ROI, fuel cost

Plus text tools, unit converters, YouTube tools, utilities, and more.

Tech Stack

Next.js 15 (static export, deployed on Cloudflare Pages)

TypeScript (strict mode)

Tailwind CSS (dark mode)

pdf-lib, pdfjs-dist (PDF processing)

Tesseract.js (OCR — WebAssembly, zero dependency on external APIs)

@imgly/background-removal (on-device AI background removal)

Kognitive Analyse für identifizierte Bedrohung: Erhöhte Bedrohungslage im Bereich I built 185 free browser tools that neve.... Basierend auf 368k Vektor-Korrelationen werden sofortige Isolationsmaßnahmen für betroffene Endpunkte empfohlen.

🛡️ Angriffsfläche & Exposure

Netzwerk/Remote-Zugriff ohne Vorauthentifizierung möglich.

⚡ Empfohlene Sofortmaßnahmen

1. Perimeter-Inspektion: Relevante Portfreigaben und exponierte Endpunkte unverzüglich scannen.
2. Patch-Applikation: Hersteller-Hotfix einspielen oder betroffene Daemons in isolierte DMZ-Segmente überführen.
3. Telemetrie & EDR-Alerts: Prozessaufrufe und Child-Processes auf anomale Shell-Spawns überwachen.
