All Free Online Tools: Browse the Complete CleverTools Directory

CleverTools is a privacy-first toolkit with 122+ free online tools for PDF, image, document, data, finance, and developer tasks. Every tool runs entirely in your browser. Your files and data never leave your device, no signup is required, and there are no watermarks or hidden limits. From compressing a PDF for a government form to generating a GST invoice or calculating income tax, this directory is the single starting point for every workflow.

Use the search above or jump straight to a category below. Popular workflows include compressing a PDF to 100KB for an upload, converting a PDF to editable Word (with OCR for scanned files), generating a GST invoice with auto CGST/SGST/IGST, and calculating income tax for FY 2025-26.

What you can do with CleverTools

  • PDF tools (24+): compress, merge, split, edit, sign, watermark, rotate, crop, redact, OCR, flatten, and convert PDFs to Word, Excel, PowerPoint, JPG, or HTML.
  • Image tools (10+): compress JPG/PNG/WebP, resize for any platform, convert formats, remove backgrounds, pick colors from images, and generate favicons.
  • Data and developer tools (13+): format and validate JSON, convert between JSON/XML/CSV, decode JWT, encode Base64, generate hashes, test regex, build cron expressions, and write CSS gradients.
  • Finance and tax calculators (India): income tax (FY 2025-26), HRA exemption, 80C deductions, TDS, EMI, FD/RD, and loan eligibility, all aligned with current Indian tax rules.
  • India-specific document tools: GST invoice generator, salary slip generator, rent receipt generator, UPI QR code generator, IFSC and HSN/SAC code finder, Aadhaar/PAN masker, PAN form filler, and an ATS-friendly resume builder.
  • Productivity and utility tools: password and QR generators, word counter, text diff checker, age and percentage calculators, time-zone scheduler, meeting cost calculator, email extractor, and WhatsApp helpers.

Why CleverTools is different

Most online tool sites upload your files to a server, run conversion, and email you the result, which means your sensitive PDF, Aadhaar, or tax document briefly lives on someone else's machine. CleverTools is built differently: every conversion, calculation, and edit happens inside your browser using JavaScript, WebAssembly, and modern Web APIs. Nothing is uploaded, nothing is logged, and there is no account to create.

The toolkit is also free of the dark patterns common to free online tool sites: no surprise watermarks, no daily limits, no trial flows that ask for a credit card before downloading the result. If a tool exists in this directory, the full feature set is free forever.

Frequently asked questions

Are CleverTools really free?

Yes. Every tool in this directory is free, with no signup, no credit card, and no usage limits. There are no watermarks on output files and no paywalled features.

Are my files uploaded to a server?

No. Every tool runs entirely in your browser. Your PDF, image, or document never leaves your device. We can't see your files because they never reach our servers.

Which tool should I use to compress a PDF for a government form?

Start with Compress PDF and choose the Extreme level. Most text-based PDFs can be reduced to under 100KB while staying legible.

Do the India-specific tools follow current tax rules?

Yes. The income tax, HRA, 80C, and TDS calculators are aligned with the FY 2025-26 slabs and rules under both the old and new tax regimes. The GST invoice generator supports all five GST slabs (0%, 5%, 12%, 18%, 28%).

How often are new tools added?

New tools are added regularly based on user requests and search demand. The current directory has 122+ tools, and the roadmap focuses on India-specific document and finance workflows.
