Online Tools & Calculators

Complete suite of browser-based image processing tools that never upload your photos to any server—all processing happens locally in your browser using JavaScript. Compress images to reduce file sizes by 40-80% for faster website loading, reduced storage costs, and improved Core Web Vitals scores, all while maintaining visual quality through smart optimization algorithms that preserve important details.

Our Image Editor & Optimizer is an all-in-one tool that lets you compress to reduce file size, resize to exact dimensions (perfect for social media requirements), and crop to any aspect ratio with precision. Resize images for specific social media platforms (Instagram posts, stories, Facebook covers, Twitter headers), email attachments that have size restrictions, or website requirements with pixel-perfect dimension control.

Convert between formats seamlessly—JPG to PNG for transparency support, PNG to JPG for smaller file sizes, with batch conversion capabilities for handling multiple images efficiently. Extract text from scanned documents, receipts, business cards, or screenshots using advanced OCR (Optical Character Recognition) technology. Create passport-size photos with correct dimensions, background color, and alignment for official documents. Apply aesthetic filters or convert photos to pencil sketches for creative projects. Generate QR codes for sharing URLs, contact information (vCard format), or Wi-Fi credentials.

Comprehensive PDF management tools for document workflows, business operations, and personal organization. Merge multiple PDFs into a single file for easier distribution—combine contracts, invoices, reports, or presentation materials into one organized document. Split large PDFs into individual pages for selective sharing, or extract specific page ranges for focused distribution without revealing the entire document.

Compress oversized PDFs to meet email attachment limits (typically 25MB for most email providers) while preserving readability and important formatting. Our compression algorithms reduce file size by optimizing images, removing redundant data, and streamlining PDF structure. Convert Word documents (DOC, DOCX) to PDF format for universal compatibility and professional distribution, or convert PDFs back to editable Word format when you need to modify content.

Transform image collections into organized PDF files—scan multiple documents and combine them into a single searchable PDF, convert photo albums to digital PDF books, or compile presentation slides into distributable format. Extract PDF pages as individual images (JPG or PNG) for presentations, social media sharing, or web publishing. All PDF operations use client-side JavaScript libraries, meaning your documents are processed entirely in your browser without server uploads—critical for confidential business contracts, personal financial statements, medical records, or sensitive legal documents.

Health and wellness tools designed to support personal fitness tracking, nutrition planning, and time management. Calculate precise age in years, months, and days for legal documentation, insurance applications, school admissions, or milestone celebrations. Our age calculator accounts for leap years and provides exact duration calculations between any two dates.

Assess health metrics with our BMI & Calorie Calculator that follows WHO (World Health Organization) classification standards. Beyond basic BMI calculation, it estimates your ideal weight range based on height, calculates Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation, and determines daily caloric needs based on activity levels (sedentary, lightly active, moderately active, very active). This helps with weight management, nutrition planning, and fitness goal setting with science-backed recommendations.

Financial and shopping calculators include discount and percentage tools for calculating sale prices, tax amounts, tip percentages, salary increases, or business pricing strategies. Find the exact difference between two dates for billing periods, project timeline management, rental agreements, loan tenure tracking, or age verification. Calculate attendance-based salary deductions common in shift-based employment, or determine cost per unit for price comparisons across different package sizes. All calculations include detailed explanations of the formulas used and practical real-world application examples.

Essential conversion utilities for international commerce, education, and technical workflows. Our Currency Converter supports 150+ global currencies with real-time exchange rates updated multiple times daily from reliable financial data sources. Convert currencies for international travel planning, cross-border e-commerce transactions, freelance invoicing in different currencies, import/export business calculations, or investment portfolio tracking across multiple markets.

Comprehensive Unit Converter handles 100+ measurement types across length (meters, feet, miles, kilometers), weight (kilograms, pounds, ounces, tons), temperature (Celsius, Fahrenheit, Kelvin), volume (liters, gallons, milliliters), area, speed, time, and data storage. Essential for cooking recipe conversions, construction and engineering projects, scientific calculations, educational assignments, international shipping, or everyday measurement needs when working across metric and imperial systems.

Convert between Roman numerals and Arabic numbers—useful for understanding historical dates, analyzing legal documents with Roman numeral sections, working with clock faces, or educational purposes. Transform annual salary figures to monthly equivalents for budget planning, or convert monthly subscription costs to annual totals for cost comparison. All converters provide instant, accurate results with explanations of conversion factors and formulas used.

Text analysis and manipulation tools for writers, students, content creators, and developers. Our advanced Character Counter tracks characters, words, sentences, paragraphs, reading time, and byte size in real-time. It shows character counts with and without spaces (critical for Twitter's 280-character limit), calculates SMS message segments (standard SMS supports 160 characters, but special characters reduce this to 70), and displays byte size for database field planning or API payload estimation.

Word Counter provides detailed text statistics including word count, average word length, sentence count, paragraph count, estimated reading time at different speeds (slow, average, fast), and speaking duration for presentations. Essential for meeting essay requirements, blog post optimization (SEO best practices recommend 1,500-2,500 words for ranking content), social media caption planning (Instagram supports 2,200 characters), or academic writing assignments with strict word limits.

Text manipulation tools include features to remove duplicate lines from lists, eliminate empty lines for data cleaning, remove line breaks for continuous text formatting, reverse text for creative social media posts or puzzles, and compare two text blocks to identify differences. All text processing happens instantly in your browser with complete privacy—your drafts, proprietary content, confidential documents, or personal writing never leave your device or get transmitted to any server.

Miscellaneous professional and productivity tools for everyday digital tasks. Generate QR codes instantly for sharing website URLs (perfect for business cards, marketing materials, or event posters), contact information in vCard format (automatically populate phone contacts when scanned), Wi-Fi network credentials (guests can connect without typing complex passwords), event details, payment information, or location coordinates.

No software installation required; create unlimited invoices completely free.

Format and validate JSON data with our JSON Formatter & Validator—essential for developers working with APIs, configuration files, or data exchange. Beautify minified JSON for readability, validate syntax for errors, minify JSON for production deployment, or convert between JSON and other formats. Convert written text to natural-sounding speech using Text-to-Speech technology for accessibility features, language learning practice, proofreading by listening, or content consumption while multitasking. Check multiple time zones simultaneously with our World Clock tool—perfect for scheduling international meetings, coordinating with remote teams, or planning global travel.
