Tool 01

QR Code Generator

Runs entirely in your browser. Nothing you type is sent anywhere.

⚙ 100% client-side — no network call
Tool 02

Resume ATS Checker

Upload a resume (PDF, DOCX, or TXT) and paste a job description. Scoring happens locally in your browser — files are never uploaded to a server.

⚙ Parsed in-browser — file never leaves your device
Tool 03

PDF to Word Converter

Extracts text page-by-page from your PDF and rebuilds it as an editable .docx — processed fully in-browser. Complex layouts (multi-column, embedded tables) convert as plain flowing text, not pixel-exact clones.

⚙ Runs in-browser via pdf.js — file never uploaded
Tool 04

Image Compressor

Drag in a JPG, PNG, or WebP. Compression runs on-device via the Canvas API — nothing uploads.

⚙ 100% client-side — no network call

Tool 05

Background Remover

Uses a small on-device segmentation model to cut the subject from its background. First run downloads the model (~15–40MB) once, then everything runs locally.

⚙ WASM model runs in your browser — image never uploaded
Tool 06

Website SEO Checker

Browsers block cross-origin page fetches (CORS), so instead of an address bar this checks the page's actual HTML source — paste it in, or use "View Source" / "Inspect" on the page you're auditing.

Tool 07

Password Generator

Uses your browser's cryptographically secure random number generator. Nothing is transmitted or stored.

⚙ crypto.getRandomValues — no network call
Tool 08

Invoice Generator

Fill in details, preview live, export as a PDF. Templates save to your browser's local storage — no account needed.

Tool 09

Sitemap Generator

Browsers can't crawl arbitrary domains (no CORS access, and no server here to crawl on your behalf). Instead: paste your page URLs — one per line, from your CMS export, server logs, or a local crawler — and get back a valid sitemap.xml.

Image Compressor

How to compress images without losing quality

Shrinking a photo's file size doesn't have to mean visible artifacts. The trick is lowering redundant color data rather than resolution: JPEG quality between 65–80% usually halves file size with a difference only visible when you zoom past 200%. Keep PNGs for screenshots and flat graphics, JPEG for photos, and always compare before/after at 100% zoom before publishing.

Resume ATS Check

Why your resume gets rejected before a human sees it

Most mid-size companies now filter resumes through an applicant tracking system before a recruiter opens them. These systems score resumes by keyword overlap with the job description and penalize tables, images, and multi-column layouts that break text parsing. A single-column, plain-text-friendly resume with the exact skill words from the posting will consistently outscore a fancier design.

Check your resume
QR Codes

QR codes for menus, Wi-Fi, and business cards

A QR code is just a container — what matters is what you put in it. Menus work best as a direct link to a hosted PDF or page, not a downloadable file. Wi-Fi codes save guests from typing long passwords. For business cards, a vCard or contact-link QR converts far better than a plain URL to your website homepage.

Background Remover

Getting clean edges when removing a background

Automatic background removal struggles most with fine detail — hair, fur, semi-transparent fabric. For the cleanest cutout, shoot against a plain, evenly lit background and avoid busy patterns behind the subject. If edges still look rough after removal, zoom in at 200% and check the hairline before exporting.

Passwords

What actually makes a password hard to crack

Length beats complexity. A 16-character password drawn from a large character set takes exponentially longer to brute-force than an 8-character one stuffed with symbols. Reusing a strong password across sites is still the biggest real-world risk — a password manager solves that; a longer password alone doesn't.

SEO Checker

The on-page SEO basics worth checking first

Before chasing backlinks or technical audits, confirm the basics are actually in place: a unique title tag under 60 characters, one clear H1, a meta description that earns the click, and alt text on every meaningful image. These small, structural fixes are the highest-leverage SEO work most sites skip.

FAQ

Common questions

Is GoToolsAI really free? +
Yes. All nine tools are free to use with no account, no usage cap on the core features, and no watermark on your files.
Do my files get uploaded to a server? +
No, for every tool that touches a file — resume checker, PDF to Word, image compressor, background remover — processing happens locally in your browser. The file never leaves your device.
Why can't I just paste a URL into the SEO checker or sitemap generator? +
Browsers block a page from fetching another site's raw HTML directly (a security rule called CORS), and this tool has no backend server to route around it. Instead, paste the page's HTML source (View Source) into the SEO checker, or paste your list of URLs into the sitemap generator — both give you the same result without needing a live fetch.
How accurate is the PDF to Word conversion? +
Text and paragraph structure carry over cleanly. Complex layouts — multi-column pages, embedded tables, precise graphic placement — convert as flowing text rather than a pixel-exact copy, since that's a fundamentally harder problem than plain text extraction.
Does the resume checker guarantee I'll pass a company's ATS? +
No single tool can guarantee that — every company's ATS is configured differently. This tool checks the same fundamentals most systems look for: keyword overlap with the job description, standard section headers, and parseable formatting.
Is there a file size limit? +
Yes, uploads are capped at 10MB per file across the file-based tools, mainly so processing stays fast in-browser rather than for any privacy reason.
