ZeeSharp was built on a simple idea: everyday digital tasks — compressing an image, converting a PDF, formatting JSON, generating a password — should take seconds, not minutes. Every tool on this page is completely free, works in your browser without any installation, and requires no account or sign-up.
Most tools process files and data locally in your browser using JavaScript APIs, meaning your sensitive documents and images never leave your device. For server-side operations (like PDF processing or AI background removal), files are deleted from our servers immediately after processing.
Convert PDFs to Word documents, compress large PDFs, split multi-page documents, merge files, password-protect sensitive PDFs, and export PDF pages as high-resolution images. All powered by the pypdf and PyMuPDF libraries on our server.
Compress JPG, PNG and WebP files, convert between formats, crop and resize images, remove backgrounds with AI (U2Net model), add text or logo watermarks, view EXIF metadata, and convert images to Base64 data URIs.
Convert text between UPPERCASE, lowercase, camelCase, snake_case and more. Count words, characters and reading time. Compare two texts side by side. Remove duplicate lines. Generate Lorem Ipsum placeholder text. Convert Markdown to HTML.
Format and validate JSON, generate UUIDs in bulk, encode/decode HTML entities, convert between number bases (decimal, binary, hex, octal), test regular expressions with live highlighting, and convert Unix timestamps to readable dates.
Generate cryptographically secure passwords, compute MD5/SHA-256/SHA-512 hashes of text and files, decode JWT tokens to inspect their payload and expiry, and encode or decode Base64 strings — all client-side, nothing transmitted.
Build CSS gradients (linear, radial, conic) visually, create multi-shadow box-shadow effects with live preview, pick colours and convert between HEX, RGB, HSL, HSV and CMYK formats, and generate favicons in all 8 standard sizes.
Convert between 10 categories of units (length, weight, temperature, area, volume, speed, time, data, pressure, energy), convert currencies with live exchange rates from 30+ countries, convert time zones across the world, and generate QR codes for any data.
Calculate percentages, find the percentage change between two numbers, calculate exact age from a birthdate with next birthday countdown, convert between Arabic and Roman numerals, and generate batches of random numbers with statistics.
Calculate concrete volumes and cement/sand/aggregate quantities, estimate bricks, tiles, paint and flooring, design staircases, size rebar schedules, calculate roofing sheets and get detailed project cost estimates by grade and location.
Apply Ohm's Law to solve for voltage, current, resistance and power. Calculate voltage drop, wire size, LED resistor values, electricity bills, power factor with capacitor correction, three-phase power, battery backup and motor full-load amps.
Perform matrix operations up to 5×5, solve polynomial equations up to quartic degree, work with complex numbers in rectangular and polar form, compute statistics and probability distributions, solve linear systems with Gaussian elimination and more.
Analyse keyword density in any page content, inspect Open Graph meta tags, check readability scores, validate robots.txt files, and generate optimised meta tags for better search engine visibility — all client-side and free.
