CryptoWave — SEO & Polish Update

a31139027- — Mon, 30 Mar 2026 02:59:49 +0000

https://cryptowaveapp.com/
CryptoWave — 33+ free browser-based crypto, media, and utility tools. No uploads, no servers, no accounts.

What I shipped today
This week I focused entirely on SEO fixes and site polish. No new features — just making what already exists work better for search engines and users.

Fixed Google Search Console redirect errors

Cloudflare Pages automatically strips .html from URLs (e.g. /pages/audio.html → /pages/audio). My canonical tags still had .html in them, so Google was flagging every page as a "redirect error." Batch-replaced all 35 canonical URLs across the site to remove the extension. Also updated sitemap.xml to match.

Split hash.html into dedicated pages

hash.html was a single page covering SHA-256, MD5, SHA-512, HMAC, and Bcrypt — five algorithms in one URL. Split SHA/MD5 and Bcrypt into their own dedicated pages (sha256.html, bcrypt.html), each with their own title, meta description, canonical URL, and JSON-LD schema. This gives each algorithm a chance to rank independently.

Added HowTo schema + expanded FAQs

Added JSON-LD HowTo schema (step-by-step instructions) and expanded FAQs from 3 to 6+ items on 10 tool pages. These are the two content formats Google most commonly surfaces as featured snippets.

Added Related Tools section

Injected a "Related Tools" section before the footer on every page via a single JS function. No changes needed to individual HTML files — just one RELATED map in utils.js. Internal linking helps Google understand site structure and passes PageRank between pages.

Fixed alert text invisible in light mode

Had hardcoded color: #f5dec8 (a light cream) on .alert--info. Fine on dark background, completely invisible on light. Changed to color: var(--text-primary) so it respects the active theme.

Updated branding

Replaced the emoji favicon with a proper transparent PNG app icon. Updated the navbar logo to match. Also added og:image for social sharing previews (for Threads/Twitter cards).

Numbers
Pages with HowTo schema: 10
Pages with expanded FAQ (6+ Q&A): 10
Internal links added: ~120 (3–4 per page × 34 pages)
New dedicated pages: 2 (sha256, bcrypt)
GSC redirect errors fixed: 9
What's next
Submit new pages to Google Search Console for indexing
Monitor GSC coverage report over the next 2–3 weeks
Add more tools based on search demand

How I Built a 100% Private, Browser-Side Toolbox with AI as My Co-Pilot

a31139027- — Thu, 26 Mar 2026 01:37:22 +0000

Hi everyone! 👋

I wanted to share a project I’ve been working on called CryptoWave. It’s a collection of essential developer and utility tools (like AES encryption, audio converters, and image compressors) that run entirely in your browser.

Why I built this
We’ve all been there: you need to convert a quick file or encrypt a snippet of text, but the top Google results are often cluttered with ads and, more importantly, they require you to upload your data to their servers.

As someone who values privacy, I thought: “Why can’t we do all of this locally?” With modern browser power and WebAssembly, we should never have to send private files to a random server just for a simple conversion.

The "AI + Solo Dev" Workflow 🤖
I want to be transparent: I built this with significant assistance from AI (like Gemini). As an independent developer, AI acted as my senior architect and debugging partner. It helped me:

Implement complex crypto logic: Ensuring AES and RSA operations were handled correctly using CryptoJS.

Wrangle WebAssembly: Using AI to help bridge the gap in setting up FFmpeg.wasm for local audio and video processing.

UI/UX Refinement: Quickly iterating on a clean, dark-mode professional interface that stays lightweight.

This project is a testament to how AI can empower a single developer to build tools that previously required a whole team.

Key Features of CryptoWave
🔒 100% Client-Side: Your data never leaves your computer. Period.

🎥 Media Tools: Convert audio and compress images locally using your browser's RAM.

🔐 Developer Utilities: AES/RSA encryption, SHA/MD5 hashing, JWT decoding, and more.

🚀 Zero Tracking: No cookies, no logs, no nonsense.

Tech Stack
Frontend: Vanilla JavaScript, HTML5, CSS3 (No heavy frameworks for maximum speed).

Processing: FFmpeg.wasm, CryptoJS.

Deployment: Vercel.

Check it out
I’d love for you to try it out and let me know what you think:

I have a question for the community: How has AI changed your development workflow this year? Have you used it to tackle a specific technical hurdle like I did with WASM?

I’m looking forward to your feedback and suggestions for new tools to add!
