Every ToolAdda tool, organised by the job

Every Indian exam portal sets its own rules: the photograph must be a certain pixel size, the signature has to be a separate file, and both must come in under a hard limit in kilobytes. This is where most people get stuck. Start with Passport Size Photo Maker, which crops to standard document sizes. Prepare the signature separately in Signature Resizer. Then deal with the file size — if the form says "under 20 KB", use Compress Image to Exact KB, which targets a hard limit; if you are compressing a whole folder, Image Compressor is the better fit. Photo taken on a phone and saved as .HEIC that the portal refuses? HEIC to JPG/PNG Converter turns it into a JPG.

Forms often want the photo and signature inside a single PDF. Use Images to PDF first, then PDF Compress if the result is too large.

Most of the effort in conducting an exam goes into paperwork rather than teaching. Paper Generator prints ruled, graph and dot-grid sheets; Worksheet Generator produces maths and handwriting practice. For a multiple-choice paper, OMR Sheet Generator builds a printable answer sheet with a roll-number bubble grid, including NEET and JEE presets. And the job that used to take an evening by hand — Exam Seating Arrangement Planner — turns roll-number ranges and room sizes into a seating chart where no two students from the same class sit next to each other, along with room-wise attendance lists and a door notice for every hall.

These tools are India-first, and they are the part of ToolAdda that global alternatives simply do not cover. Salary Slip Generator produces payslips with EPF, ESI and state-wise professional tax, and supports bulk CSV. To send a bill, Offline Invoice Generator gives you the full document — letterhead, HSN codes, shipping, round-off and the amount in words; if you only need to check one figure, GST Calculator is enough. For an HRA claim there is Rent Receipt Generator. Job hunting? Resume Builder exports a text-based PDF or DOCX, and ATS Resume Checker scores a resume you already have against a specific job description.

Neither the Resume Builder nor the ATS Checker uses an LLM. Scoring is based on keyword matching and how cleanly the file parses, not on an AI opinion.

EMI Calculator handles the general loan case; for a house or a car, Home Loan Calculator and Car Loan Calculator add domain-specific inputs. On the investment side there are SIP Calculator, PPF Calculator, FD Calculator and RD Calculator. All of them display figures in the Indian lakh and crore format, and wherever a statutory rate is applied the page carries a "last reviewed" date and leaves the rate editable — because those rates change by state and by establishment.

PDF Tools Hub opens everything in one place for day-to-day work. The common operations are straightforward — PDF Merge, PDF Split, PDF Compress, PDF Rotate and Add Watermark to PDF. Two of them are routinely confused, so to be explicit: PDF Extract pulls out the pages you choose (despite the name it does not extract text), whereas PDF Split divides a whole document by a rule. And when something hidden has to be genuinely gone rather than merely obscured, you want Redact PDF, because it destroys the underlying text.

PDF Password Remover is only for a PDF whose password you already know. It cannot crack or bypass an unknown one.

The basics — Image Resizer, Image Crop Tool, Image Rotate Tool, Image Blur Tool and Grayscale Image Converter — all run inside the browser, which means your photo is never uploaded anywhere. Image Background Remover strips the background, Image Color Picker reads an exact hex value out of any image, and Poster Printer spreads one image across several A4 sheets to make a large poster. One tool worth knowing for privacy reasons: EXIF Metadata Remover strips GPS coordinates and camera details out of a photo before you post it.

Image Blur Tool hides something visually. If it matters that the hidden content cannot be recovered, do not use an image — use Redact PDF instead.

For a plain code, QR Code Generator is enough. If you need branding — a logo, custom colours, different styles — use Custom QR Code Maker. For products and inventory, Barcode Generator supports seven barcode types. And when you need a hundred rather than one, QR & Barcode Label Sheet Generator lays them out from a bulk CSV onto A4 label sheets. To read a code, QR Code Scanner works from either the camera or an uploaded image.

Online Notepad gives you somewhere to write without an account, and keeps working offline after the first visit. For everyday text work there are Case Converter, Character Counter and Text Sorter. For social there are Fancy Font Generator, Emoji & Kaomoji Picker and LinkedIn Post Previewer, which shows exactly where a post gets cut off by "see more" in the feed. Two stand out: Text to Handwriting Converter converts typed text into convincing handwriting (twelve styles, ruled paper, multi-page PDF, no watermark), and WhatsApp Chat Analyzer turns an exported chat into message statistics, activity charts and response times — entirely inside your browser.

Moving data between formats is the most common task: JSON Formatter, JSON to YAML, JSON to CSV Converter, JSON to XML Converter, CSV to JSON Converter, XML to JSON Converter and JSON to TypeScript, which generates TypeScript interfaces from a JSON sample. For debugging, JWT Debugger decodes and verifies an existing token while JWT Encoder mints a new one. Regex Tester tests a pattern live, Cron Expression Generator makes cron syntax readable, and Epoch / Unix Timestamp Converter takes the guesswork out of timestamps.

Shadow Generator builds layered CSS shadows that look far more natural than a default box-shadow. To actually understand a layout, CSS Flexbox & Grid Playground shows every property changing live. For current styles there are CSS Glassmorphism UI Builder, CSS Neumorphic Element Designer and Bento Grid Generator, and scroll-driven animations come from Scroll Animation Keyframe Builder. All of them emit CSS you can paste straight into a stylesheet.

Website SEO Checker runs an on-page audit of a URL, Sitemap Generator builds a sitemap, and robots.txt Generator & Tester writes and tests a robots.txt. To check link structure, Dofollow & Nofollow Link Checker classifies every link from its rel attribute. On the network side there are DNS Lookup and DNS Propagation Checker, which compares four independently operated resolvers rather than faking a world map of locations. Campaign links come from UTM Builder.

These networking tools have to reach the internet, so do not describe them as fully private. Almost everything else on the site runs entirely in your browser.

Password Generator creates strong passwords and Password Strength Checker tells you how long an existing one would hold up. Hash Generator MD5/SHA produces MD5 and SHA checksums. If you work on servers, SSH Key Generator creates key pairs, and PEM to PPK Converter and PPK to PEM Converter convert between the OpenSSH and PuTTY formats. For privacy, EXIF Metadata Remover strips location data out of a photo, and Image Steganography hides a message inside an image.

PEM to PPK Converter handles unencrypted RSA keys only and outputs PPK v2. It will not convert Ed25519 or ECDSA keys, which are what ssh-keygen produces by default today.

Interactive Periodic Table is interactive and carries the properties of every element. Chemical Equation Balancer balances equations step by step using exact integer arithmetic rather than guessing. Electron Configuration Builder builds the configuration for any element, Half-Life Calculator & Radioactive Decay Simulator draws a live decay curve, and 3D Molecular Structure Viewer lets you rotate molecules in 3D.
