How this actually works
Each tool runs entirely with JavaScript already loaded in this page — PDF tools via pdf-lib and pdf.js, image tools via the browser's native Canvas API, and everything else with plain JavaScript. Your files or input are read into browser memory, processed, and handed back as a download or copyable result. This page itself is served by a small Laravel route; Laravel never sees your files either. The only backend in use is Supabase, and only for two optional things: signing in with a magic link, and — only if you're signed in — a log of which tool you ran and when. Honest limits worth knowing: Compress PDF flattens each page to a re-encoded image (great for scans, not ideal if you need selectable text after); HEIC conversion uses a small on-demand converter when the browser cannot decode HEIC natively (Safari often works without it); Fill PDF Form is best-effort for simple AcroForm fields, not a full Adobe Forms replacement; and Word/Excel/PowerPoint ⇄ PDF genuinely needs a server-side engine, so it isn't included — this build only ships tools that can honestly run client-side.
Questions people actually ask
What compounding frequency does this assume?
Quarterly — the standard convention Indian banks use for Fixed Deposit interest, unlike the more flexible frequency choice in the general Compound Interest Calculator.
Does it account for TDS (tax deducted at source)?
No — this shows the gross maturity value and interest before any tax; banks may deduct TDS on interest above a threshold, which isn't modeled here.
What if my bank compounds differently, like monthly?
Use the general Compound Interest Calculator instead, which lets you choose the compounding frequency directly — this FD Calculator is specifically for the common quarterly-compounding convention.
Does it account for premature withdrawal penalties?
No — this calculates the full-term maturity value assuming the deposit runs its complete tenure; early withdrawal typically reduces the effective rate, which this doesn't model.
Is this official financial advice?
No — it's a convenience calculator for estimates, not professional financial advice. Confirm exact figures with your bank.
Can I use this for a non-Indian fixed deposit product?
The math (quarterly compound interest) is generic, but confirm your bank's actual compounding convention first — not every country's FD-equivalent product compounds quarterly.
Does it show interest earned separately from the total?
Yes — both the total maturity value and the interest portion alone are shown, so you can see exactly how much your money grew.
Is my amount sent anywhere?
No — the calculation happens entirely in your browser as you type; nothing is transmitted.
Is this really free, and is there a file size limit?
Yes — no account, no paywall. Since processing happens in your browser's memory rather than uploading anywhere, the practical limit is your device's available RAM, not a server quota. Very large files (500+ pages) may run slower, especially for Compress and PDF→JPG.
Does anything about my file get sent anywhere?
No. Every tool runs with pdf-lib/pdf.js loaded in this page; your file is read into browser memory and never leaves it. The only network call this app makes for your account is Supabase auth — and that only stores which tool you ran and when, never file content.
Why isn't Word/Excel/PowerPoint → PDF included?
Converting Office formats accurately needs a real rendering engine (what Word or LibreOffice use internally) — no browser library does this reliably. Rather than ship a broken version, it's left out.
Does TechDriven Tools have OCR (text recognition)?
Yes — OCR PDF recognizes text in scanned or photographed pages using Tesseract.js, running entirely on your device, and gives you a searchable PDF or a plain text file. Nothing is uploaded for this either.
Can I use this without an internet connection?
Once the page and its libraries have loaded once, yes — the tools themselves need no network access. Signing in and viewing history do require a connection, since those talk to Supabase.
What happens to the "history" if I sign in?
Only a row per tool run — the tool's name and a timestamp. No filename, no file content, ever. You can see the full list any time via the History button.
Are the non-PDF utilities (password generator, JSON formatter, etc.) private too?
Yes — same rule as the PDF tools. Word Counter, Case Converter, Password Generator, UUID Generator, Base64, Hash Generator, JSON Formatter and JWT Decoder all run with plain JavaScript already loaded in this page; nothing you type or paste is sent anywhere.
FD Calculator, in depth
Calculate the maturity value of a Fixed Deposit, using standard quarterly-compounding conventions.
Features
Maturity Value
The exact amount your FD grows to.
Interest Earned
The gain, separate from your original deposit.
Quarterly Compounding
Matches how most banks actually compound FD interest.
Live Calculation
Updates instantly as you adjust any input.
Why use FD Calculator
- Compare FD offers from different banks at different rates or tenures.
- Check a bank's advertised maturity value independently.
- Plan around a specific maturity amount for a future goal.
- Understand how tenure affects total interest earned.
How it works
Most banks compound FD interest quarterly, not annually — this calculator uses that same convention, applying the compound interest formula with a quarterly compounding period, which produces a slightly higher maturity value than annual compounding would at the same headline rate.
FD Calculator vs. RD Calculator
An FD is a single lump-sum deposit; a Recurring Deposit involves regular monthly contributions instead. For that scenario, use RD Calculator, which accounts for each monthly contribution compounding for a different length of time.
Why people search for FD Calculator
Calculate the maturity value of a Fixed Deposit. Bookmark /fd-calculator if FD Calculator is part of your weekly workflow; the URL is stable and the tool stays free.
FD Calculator sits in our Finance group. The page is built so you can finish the job without creating an account, installing a desktop pack, or sending the payload to an unknown converter API.
Who FD Calculator is for
- A desktop suite is overkill for a one-page or one-photo job.
- You want a second opinion after another converter produced a weird output.
- You need a result now and do not want another account wall.
- The file or text is sensitive enough that uploading feels wrong.
Recommended workflow
Enter principal/rate/tenure carefully → note that outputs are estimates → confirm with a lender or advisor for real decisions.
- Open FD Calculator (also available from category hubs and ⌘K).
- Use the labeled fields or dropzone — options match what FD Calculator actually does.
- Run the tool and wait for local progress to finish.
- Download or copy the result, then verify on the device where you will share it.
Tips that improve results
- Change one setting at a time when you are comparing quality or layout.
- Keep the original until stakeholders accept the download.
- Rename the output with date + purpose before you attach it to email.
- On phones, plug in power for large PDFs, videos, or spreadsheets.
- Prefer UTF-8 text for developer converters; weird encodings cause most “broken” results.
- Start with a non-sensitive sample so you learn the options before the real file.
Common mistakes with FD Calculator
- Expecting FD Calculator to replace a full desktop suite for every edge-case format.
- Skipping a sample check and discovering a bad export after the original was deleted.
- Chaining many lossy image/PDF steps when one careful pass would have been enough.
- Using a public computer without clearing downloads afterward.
Privacy model
Processing for FD Calculator is designed to stay in the browser. Laravel serves the page; it does not receive your file bytes for conversion. Optional Supabase auth only stores which tool you ran and when — never filenames or contents.

FAQ — FD Calculator
Is FD Calculator free to use?
Yes. FD Calculator on TechDriven Tools is free — no account, no watermark, and no paywall for the core workflow.
Does FD Calculator upload my file or text?
No for processing. FD Calculator runs in your browser tab. Optional sign-in never stores file contents — only tool names and timestamps if you enable history.
When should I use FD Calculator?
Use FD Calculator for Finance jobs where privacy and speed matter: quick one-offs, sensitive inputs, or checking another app’s result without another upload site.
Will FD Calculator work on my phone?
Yes in a modern mobile browser. Large inputs can take longer because your device does the work locally.
What are the limits of FD Calculator?
There is no server quota from us. Limits are your device memory, battery, and formats the browser can decode. FD Calculator will not pretend to support server-only Office or cloud-AI pipelines.
How is FD Calculator different from upload-based sites?
Upload converters send your content to someone else’s server. FD Calculator keeps the transform on-device whenever the format allows, which is the safer default for confidential documents, photos, tokens, and configs.
Bottom line
If you need FD Calculator done quickly and privately, start at /fd-calculator, run it once on a sample, then process the real input. That is how TechDriven Tools stays competitive: honest capabilities, labeled UI, and content that matches what the tool actually ships.
