Toolbox
A place for lightweight tools that are direct, useful, and intentionally small. More like instruments on a desk than another sprawling product.
PNG to JPG
Free online PNG to JPG converter that converts a single PNG image to JPG / JPEG directly in your browser, fills transparent areas with white, and never uploads your file.
WebP to JPG
Free online WebP to JPG converter that converts a single WebP image to JPG / JPEG directly in your browser for websites and apps that only accept JPG, without uploading your file.
HEIC to JPG
Free online HEIC to JPG converter that turns iPhone photos into JPG / JPEG locally in your browser for uploads, email, and cross-device sharing without uploading your file.
Emoji to SVG
Convert multiple emoji characters into individual SVG files in your browser, switch between Twemoji and OpenMoji styles, and download one by one or as a ZIP.
Gemini Watermark Remover
Process a single Gemini image locally in the browser, remove the visible bottom-right watermark, and export the result without uploading it to the server.
Image Privacy Blur
Pixelate private information in images — faces, license plates, text, and more. All processing happens in your browser, nothing is uploaded.
Full Page Screenshot
Enter a public page URL and download a tall JPEG that captures the full scroll height. The page is opened headlessly on the server using Chromium (Playwright).
Text Diff
Compare two blocks of text line by line and quickly spot additions, removals, and unchanged content.
JS Obfuscator
Obfuscate JavaScript locally in your browser with the open-source javascript-obfuscator library, including compact output and string-array obfuscation.
HTML Formatter
Format messy HTML into readable indentation locally in your browser, with comment preservation and raw text blocks kept intact.
Markdown Reader
Paste Markdown text or upload a .md file and preview it locally in a calm, comfortable reading layout.
Mermaid Diagram
Render Mermaid diagram syntax in your browser with a pastel Flutter-style palette (light gray or black canvas), switch between rounded and square node corners, and export PNGs for light or dark layouts.
SVG Preview
Paste SVG text and preview the rendered image locally in your browser, with SVG download support. Nothing is uploaded.
Sitemap Viewer
Fetch a sitemap URL through the server, inspect prettified XML, and switch to a structured list view for sitemap entries.
Schema Viewer
Paste JSON-LD schema data, format it locally in the browser, and inspect a structured summary without sending it to the server.
World Clock
Track major global business cities in an electronic clock layout, keep daylight saving time and standard time correct automatically, and show only the cities you care about.
WordPress Password Hash Generator
Manually reset or migrate WordPress 6.8+ user passwords by generating $wp$2y$ hashes locally in the browser, with side-by-side notes on modern bcrypt and legacy $P$ phpass hashes.
Why These Tools Exist
This directory is not a random pile of links. It collects workflows I repeatedly use while building the site, writing, preparing media, and debugging small problems. Each tool page explains the use case, processing model, limits, and common questions so visitors can decide whether it fits the task.
Processing And Privacy
When comparison, conversion, or formatting can run in the browser, the site keeps it local. Tool pages state what is not uploaded to this server, and tools that rely on third-party libraries or external capabilities include notes about their source and boundaries.
How To Pick A Tool
Image
Use these when PNG, WebP, HEIC, emoji assets, or similar files need to be prepared for upload, sharing, archiving, or a lightweight cleanup step.
Text
Use these when comparing revisions, formatting HTML, inspecting structured data, or checking whether text and code look right before publishing.
Utility
Use these for small maintenance tasks that do not deserve a full app, such as checking world times or generating a WordPress password hash.
