15 Best Free Online Tools for Students in India (2026)

Between NEET prep, JEE coaching, university assignments, and CA exams, Indian students already carry a heavy cognitive load. The last thing you need is to pay ₹500/month for tools that have free alternatives. These 15 ToollyX tools are entirely free, need no account, and run instantly in your browser.

1. Word Counter — Know Exactly Where You Stand

Every university assignment, SOP, scholarship essay, and internship application has a word limit. The Word Counter shows words, characters (with and without spaces), sentences, paragraphs, lines, reading time (at 220 wpm), and speaking time (at 130 wpm) — all simultaneously, updating as you type. No need to switch to Microsoft Word just to check a count.

2. Citation Generator — APA, MLA, Chicago Without Memorising the Format

The Citation Generator supports four source types — journal articles, books, websites, and newspapers — in APA, MLA, and Chicago styles. Fill in author, year, title, and source, and it outputs the correctly formatted citation with proper italics notation. Use it for research papers, literature reviews, and any academic submission that requires a reference list. DOI and URL fields included for digital sources.

3. Reading Time Estimator — Plan Your Study Sessions

Paste any article, chapter, or study material and get reading time at adjustable speeds: default is 220 wpm (average adult reading) and 130 wpm (speaking pace). Adjust the wpm sliders to match your actual reading pace — slower for dense technical content, faster for familiar material. Useful for blocking study time when working through multiple chapters.

4. EMI Calculator — Before You Take That Education Loan

Education loans from SBI, HDFC, and Axis typically carry 10.5% interest. Before signing, calculate the exact EMI using the amortisation formula built into our calculator. For a ₹8 lakh loan over 7 years at 10.5%: EMI ≈ ₹14,920 and total interest paid ≈ ₹3.53 lakh. The half-tenure comparison shows how much you save by repaying in 3.5 years instead — a calculation most students never do before signing.

5. Merge PDF — Combine Assignment Files Before Submission

Universities require single-PDF submissions. Scan multiple pages of handwritten work, download separate sections from different sources, then merge them into one PDF in the correct order. The Merge PDF tool lets you drag-and-drop to reorder files before combining. No file size limit, no upload to server, no account needed.

6. Compress PDF — When the Portal Has a 2MB Limit

Every student has encountered a college portal with a "maximum 2MB" upload restriction that their 8MB scanned document exceeds. The PDF Compressor reduces file size through structural optimisation — Basic mode for most cases, Aggressive mode for scanned documents from older printers. Output downloads as compressed-[filename].pdfshowing the exact percentage saved.

7. Image Resizer — Passport Photos, ID Uploads, Profile Pictures

Government portals, college applications, and exam registrations all have specific image dimension requirements — "200×230 pixels, under 50KB" is a common combination. The Image Resizer lets you enter exact pixel dimensions, maintain or override aspect ratio, and control output quality. Resize to NEET's required 3.5×4.5 cm equivalent dimensions without visiting a photo studio.

8. Diff Checker — Compare Two Versions of Your Essay

When you revise a draft, it's easy to lose track of what changed. Paste your original and revised essay side by side — the Diff Checker highlights additions in green and deletions in red, line by line. Useful for tracking changes when a teacher returns a marked-up version, comparing two versions of research notes, or verifying that a group member's edit didn't accidentally remove your content.

9. GST Calculator — For Commerce and CA Students

Commerce students dealing with GST numericals in textbooks and CA Foundation papers need a quick way to verify calculations. The GST Calculator supports Add GST and Remove GST modes, all standard slabs (3%, 5%, 12%, 18%, 28%) plus custom rates, and shows CGST/SGST split alongside the IGST equivalent — exactly the breakdown tested in Board and CA exams.

10. SIP Calculator — Start Planning Early

The compounding math becomes dramatically more powerful when you start at 21 vs 35. A ₹1,000/month SIP at 12% for 35 years produces ₹65.4 lakh. The same investment starting 14 years later produces just ₹14.9 lakh. Use the SIP Calculator to see what your first job's surplus income looks like as a future corpus — it's the best financial education a student can get.

11. Lorem Ipsum Generator — Web Dev and Design Projects

CS and design students building college projects need placeholder text for UI mockups, WordPress templates, and HTML/CSS assignments. The Lorem Ipsum Generator produces text by paragraphs, sentences, or words — choose exactly how many you need. The word pool is broad enough that multiple paragraphs don't look repetitive.

12. JSON Formatter — For CS and IT Students

REST API responses, MongoDB exports, and config files come as minified JSON that's impossible to read. The JSON Formatter pretty-prints with syntax highlighting, validates simultaneously, and shows the exact line/character of any parse error. Essential for DBMS lab, web development projects, and any assignment that involves working with API data.

13. Image Converter — Convert Screenshots for Reports

Lab reports and project submissions often need images in specific formats — a PNG screenshot needs to be JPG, or a JPG photo needs to be WebP for a web project. The Image Converter handles batch conversion between JPG, PNG, WebP, and BMP with a quality slider. Drop multiple files, set the output format once, and download them all.

14. Text to Slug — For Blogs and Web Projects

Students building college project websites or personal blogs need URL slugs: "My Final Year B.Tech Project on Machine Learning" becomes "my-final-year-btech-project-on-machine-learning". The Text to Slug tool handles normalisation (removing accents), lowercase conversion, and separator choice (hyphen, underscore, or dot). Three separator options, instant output, copy button.

15. Password Generator — For Every Account You Create During College

Students sign up for dozens of services during college: LMS portals, GitHub, coding platforms, internship portals, LinkedIn, and more. Reusing passwords across all of them is the most common security mistake young people make. The Password Generator uses crypto.getRandomValues() (cryptographically secure) to create 20-character default passwords with configurable character sets and shows entropy in bits. Use the Batch tab to generate 10 passwords at once for all your new accounts.
