Practical research and checklists

ToolerWork Guides

Clear references for the decisions around a tool: which browser runtime fits, how to prepare an upload, which image format to choose, and how to review a resume before submitting it.

Browser runtime research

Browser Code Runner Compatibility Guide

Compare how Python, JavaScript, TypeScript, HTML, SQL, and React run in a browser, including WebAssembly limits, workers, loading, and mobile use.

JavaScript is the lightest browser runtime because the browser already includes its engine.
Python and SQL can run through WebAssembly, but they need a larger first-load runtime.

How these guides are built

Useful before and after the tool runs

A tool can resize a photo or run a code snippet, but it cannot decide which upload rule, runtime, file format, or resume structure fits every situation. These resources focus on that decision layer. Each guide starts with the task, explains the tradeoffs, lists a repeatable verification process, and links directly to the smallest set of tools needed to finish the work.

Technical claims use primary documentation when a stable reference is available. Portal and hiring guidance avoids invented universal limits or guaranteed outcomes. Requirements can change, so every resource shows a review date and tells readers which live instruction should remain the source of truth. A guide is reviewed again when its linked tool, browser runtime, file workflow, or primary reference changes.

Choose by task

Start with the decision blocking you

Use the browser runner guide when you need to know why Python loads differently from JavaScript, what WebAssembly can support, or whether a phone is suitable for a coding task.
Use the India document guide before changing a photo, signature, certificate, or resume for a strict portal upload field. It keeps crop, resize, conversion, and compression in the right order.
Use the image format guide when choosing between JPG, PNG, WebP, AVIF, GIF, SVG, or HEIC for a form, website, transparent cutout, screenshot, or animation.
Use the ATS checklist before exporting a resume. It covers reading order, headings, truthful keywords, date consistency, selectable text, file naming, and the final application check.
