Linkrify. Check. Analyze. Convert.
You've got a blog post to publish, a website to audit, or an image three times the size it needs to be. You don't want to create an account. You don't want a free trial that expires. You just want the tool to work — fast, free, and without asking for your email address.
Every piece of content you publish reflects your credibility. A single spelling mistake in a client proposal can cost you trust. These writing tools catch problems before your audience does.
Plagiarism Checker
Paste up to 2,000 words and scan against web sources to flag duplicate content. See which phrases match existing pages and what percentage of your text is original. For a quick originality check on a single article, it does the job without charging you a dime.
Most PopularGrammar Checker
Paste your text, click check, and the grammar checker highlights spelling errors, punctuation problems, and basic grammatical issues. Catches misplaced commas, doubled words, and missing apostrophes — fast and free.
WritingWord Counter
Instant stats: word count, character count (with and without spaces), sentence count, paragraph count, and estimated reading time. Essential for Twitter, meta descriptions, LinkedIn summaries, and academic assignments.
UtilityArticle Rewriter
Paste a paragraph or full article, and the paraphrasing tool rephrases it while keeping the original meaning. Useful for creating social media variations, simplifying technical language, or breaking through writer's block.
AI-PoweredText Summarizer
Paste a long article, research paper, or report, choose your summary length, and get the main points condensed. Students, content curators, and marketers use this to distill complex content into clear takeaways.
PopularCase Converter
Convert instantly between UPPERCASE, lowercase, Title Case, Sentence case, and aLtErNaTiNg cAsE. You've accidentally typed 500 words with Caps Lock on — this fixes it in two seconds.
Quick FixReadability Checker
Get Flesch Reading Ease, Flesch-Kincaid Grade Level, and Gunning Fog Index scores. Aim for a Flesch score between 60-70 for general web audiences. Scores below 50 mean your sentences are too long or vocabulary too complex.
SEO BoostSearch rankings don't happen by accident. Know what keywords to target, how many sites link to you, how fast your pages load, and whether search crawlers can actually find your content.
Backlink Checker
Enter any URL and get a snapshot of its backlink profile: total backlinks, referring domains, top anchor texts, and dofollow vs. nofollow ratio. Quick audits, competitor checks, confirming guest post links went live.
SEODomain Authority Checker
See Moz's Domain Authority score on a 1-100 scale. A brand-new blog sits at 5-10. Established niche sites: 30-50. Major publications: 80+. Useful for comparing against competitors and tracking your progress.
MetricsKeyword Research Tool
Enter a seed keyword and get related search terms with estimated monthly search volume, competition level, and CPC data. Find long-tail variations with lower competition that a new site can realistically rank for.
ResearchRobots.txt Generator
Select crawl or skip rules, add your sitemap URL, set a crawl delay, and download a ready-to-use robots.txt file. Includes safeguards against the most frequent mistakes like accidentally blocking your entire site.
TechnicalXML Sitemap Generator
Enter your website URL and generate an XML sitemap to submit to Google Search Console. Crawls up to 500 pages — covering most small-to-medium websites. Upload it to your root directory and submit in Search Console.
TechnicalPage Speed Checker
Total load time, page weight in kilobytes, number of HTTP requests, and specific bottlenecks. Google uses page speed as a ranking signal. Most common culprit? Oversized images — run them through the Image Compressor next.
PerformanceImages make up the bulk of most web pages' file size. A single uncompressed photo can weigh 3-5 MB — enough to add full seconds to your load time on mobile.
Image Compressor
Upload JPG, PNG, or WebP images and reduce file size without visible quality loss. Lossy compression typically reduces file sizes by 60-80%. Batch uploads supported — process multiple files at once for your blog or store.
Most UsedImage to Text / OCR
Upload a screenshot, photo of a printed document, or scanned page, and extract the text into an editable format. Works best on clean, high-resolution images with standard fonts. Saves you from retyping everything manually.
OCRImage Resizer
Upload an image, enter your target dimensions, or pick a preset (Instagram 1080×1080, YouTube thumbnail 1280×720, Facebook cover 820×312). Lock the aspect ratio to avoid stretching. Supports JPG, PNG, and WebP.
DesignWebP to JPG
Upload a .webp file and download it as .jpg. WebP produces smaller files but not every app supports it yet. Email clients, older image editors, and some social platforms still require JPG — this converter bridges the gap.
ConvertJPG to PNG Converter
Upload a JPG and get a PNG. The main reason: PNG supports transparency. For product photos on custom backgrounds, or logo files, PNG is the right format. Convert only when you actually need transparency or lossless edges.
ConvertPNG to JPG Converter
Upload a PNG and get a smaller JPG for web use. A 2MB PNG photo can drop to 300-400KB as a JPG at 85% quality with barely visible difference. Note: transparent areas become white in JPG output.
CompressFile format mismatches waste time. Your client sends a PDF you can't edit. You need to validate a chunk of JSON. These converters handle the small format problems that slow down your workflow.
PDF to Word Converter
Upload a PDF and download an editable .docx file. Maintains most formatting — headings, paragraphs, basic tables. Best results with PDFs originally created from digital documents rather than scanned images.
ConvertWord to PDF Converter
Upload a .docx and convert to PDF. PDFs display identically on every device — no font substitution, no margin shifts. The standard for invoices, assignments, contracts. Preserves fonts, images, tables, and page breaks.
DocsJSON Formatter / Validator
Paste raw, minified, or messy JSON and format it with proper indentation. Validates structure — flags missing commas, unclosed brackets, or unquoted keys with exact line and character position. Used daily by developers.
Dev ToolColor Picker / Hex Tool
Pick a color from the interactive wheel and get hex code, RGB values, HSL values, and a ready-to-copy CSS snippet. Also generates complementary and analogous color palettes for building brand color systems.
DesignYour website's technical foundation affects everything — search rankings, security, email deliverability, and uptime. These tools give you visibility into what's happening under the hood.
Whois Lookup
Enter a domain and see its registration record: registrar, creation date, expiration date, nameservers, and registrant contact info. Check domain age and history before buying, or verify your own registration won't expire unexpectedly.
DomainDNS Lookup
View A records, CNAME, MX, TXT, and NS records for any domain. Typically used after switching hosting providers, setting up a new email service, or troubleshooting why your website isn't loading after a DNS change.
TechnicalSSL Checker
Inspect a site's SSL certificate: who issued it, when it expires, the encryption standard, and whether it's correctly installed. Google uses HTTPS as a ranking signal, and Chrome shows "Not Secure" warnings on invalid certs.
SecurityWebsite Status Checker
Find out if a site is up or down right now. The tool pings the server and reports the HTTP status code and response time. Answers the first question: is it down for everyone, or just for me?
MonitoringHTTP Header Checker
View the full HTTP response headers a server sends: content-type, cache-control, server software, and security headers like Strict-Transport-Security and Content-Security-Policy. Troubleshoot caching and security issues.
Dev ToolThere are dozens of free tool websites. Most bury you in pop-up ads, force you to create an account, or hit a daily limit after one check. Linkrify takes a different approach.
Open any tool, paste your content or enter a URL, and get results. No email address, no password, no verification steps. Use every tool right now without creating an account.
Text you paste into any writing tool is processed in real time and not saved to any server. Your content stays yours — we don't build a database of user inputs or train models on your text.
Most tools return results in under five seconds. The site is lightweight — no heavy JS frameworks or bloated page designs. Get to the tool, use it, move on.
There's no "premium tier" hiding the features you need. Every tool works at full capacity for every user. The site runs on advertising revenue, which keeps tools free for everyone.
Instead of bookmarking separate websites for plagiarism checking, image compression, PDF conversion, DNS lookup, and keyword research — you have everything in a single tab.
All tools work on mobile browsers (Chrome, Safari, Firefox) on both Android and iOS. Check word counts, compress images, or run a plagiarism scan from your phone.
Bloggers & Writers
Run every article through the plagiarism checker and grammar checker before publishing. Use the word counter for assignment targets and readability checker to avoid overly dense web copy.
Web Developers
Check DNS records after migrating a client's site, verify SSL certificates, inspect HTTP headers when troubleshooting. The JSON formatter saves time when debugging API responses.
Students
Use the plagiarism checker for essay submissions, text summarizer for research, word counter for assignment requirements. The paraphrasing tool helps rephrase cited material in their own words.
Small Business Owners
Compress product images before uploading to Shopify or WooCommerce, convert invoices between PDF and Word, and check page speed to see if slow loading is costing customers.
