WebTools Engine
81+ free, browser-based tools for PDF, image, SEO & more — n
WebTools Engine is a free, all-in-one hub of 81+ high-utility web tools built for developers, marketers, students, and freelancers who are tired of bouncing between a dozen different websites just to merge a PDF, generate a QR code, or check an image's file size.
Most free tool sites specialize in one narrow category, force a sign-up wall, bury the actual tool under ads, or upload your files to their servers before processing them. WebTools Engine takes a different approach: everything lives in one place, no account is ever required, and most tools run entirely client-side in the browser — meaning your files and data are processed on your own device and never touch a server.
What's inside:
• PDF Tools — merge, split, rotate, delete pages, add watermarks, and convert PDF to JPG or Word
• Image Tools — compress, resize, crop, remove backgrounds, and strip EXIF/GPS metadata for privacy
• SEO Tools — meta title/description checker, readability score calculator, schema markup validator, robots.txt checker, XML sitemap generator, and a website carbon footprint calculator
• Calculators — loan/EMI, TDEE, BMI, discount, VAT/tax, age, and date calculators
• Generators — QR code, barcode, password, UTM campaign builder, CSS gradients, and box-shadow generators
• Developer Tools — JSON formatter, regex tester, JWT decoder, text diff checker, hash generator, Base64 encoder/decoder, and classic ciphers (AES, Caesar, Morse)
• Text Tools — word/character counters, case converter, duplicate line remover, and text cleaner
Every tool is completely free with no premium tier, no usage caps, and no forced registration — the goal is to get in, solve the problem, and get out, as fast as possible.

Comments
Having PDF, image and SEO utilities all client-side is the standout feature here — most tool sites upload files to a server, so keeping processing in the browser is a real privacy win. One suggestion: surfacing the TDEE/BMI calculators more prominently on the homepage could help people land on the highest-use tools first.
Hey Fazier community! 👋 I built WebTools Engine because I kept bouncing between 5+ different websites just to merge a PDF, generate a QR code, or check an image's file size — each with its own sign-up wall, ads, or upload limits. So I put 81+ genuinely useful tools (PDF, image, SEO, calculators, generators, dev utilities) in one place. No sign-up required, and most tools run entirely in your browser — your files never touch a server. Would love feedback from anyone who tries it, and happy to answer any questions about how it's built!
Keeping PDF, image, and SEO tools in one browser-based place removes a real friction point, since most alternatives push sign-ups or upload files to a server. Two questions: does the PDF merge handle large multi-file merges smoothly, and do you plan a batch mode for processing several files at once?
Working on a free browser-based toolkit myself, so WebTools Engine caught my eye — 81+ free, browser-based tools for PDF, image, SEO & more — n. The way it's laid out makes the value clear fast. One question: what's the one use case you've seen users return to most? Curious whether it's the core feature or an unexpected one.
Running the tools client-side is the real differentiator here. Most free PDF and image sites quietly upload your file, and that's a deal-breaker for anything with client data. It might be worth making that visible on each tool page, with a small "processed on your device, never uploaded" label, because people won't read the homepage before dropping a contract into "merge PDF". Which of the 81 tools still need a server, and do you flag those differently?
The JWT decoder is the tool where client-side matters most: a pasted token is a live credential until it expires, so it would be worth saying right on that page that decoding happens locally and nothing is logged. Same idea for the regex tester: a pattern like (a+)+$ against a long input can freeze the tab, so running matches in a Web Worker with a timeout would keep the page responsive. Nice set of tools.
The client-side processing is the right call, especially for the JWT decoder — pasting a live token into a server would be a real security concern. One suggestion: add a small badge on each tool card showing whether it runs fully locally vs. server-assisted, so users know at a glance which ones are private by design.
The SEO toolkit is the part I'd actually bookmark — meta title/description checker and readability scoring are things I currently use separate sites for. Running the image tools client-side is a real trust-builder too. One idea: a unified search across all 81 tools would make the hub much more navigable. Solid launch!
