Explore Premium ToolsThese are working tools rather than calculators. They convert a file, generate a document, track something over time or process text. Where a calculator answers a question, these produce an output you keep — a filled invoice, a compressed image, a converted spreadsheet, a password.
All of them are free and none requires an account. Just as importantly, the file tools do their work inside your browser: your document is never uploaded to a server, which matters when the file is a contract, a payslip or a medical form.

Most free file converters online work by uploading your document to a server, processing it there and sending the result back. That is simple to build and it means a copy of your file sits on someone else's infrastructure, subject to their retention policy and their security.
For a holiday photo that hardly matters. For a signed contract, a tax return, an employment agreement or a medical record it matters a great deal. The tools here run entirely in your browser using JavaScript, so the file never leaves your device — you can watch this yourself by disconnecting from the internet after the page loads and confirming the tool still works.
If you are producing tax invoices, there are specific things the ATO requires them to show. For sales of $82.50 or more including GST, a valid tax invoice needs your identity and ABN, the date, a description of what was sold, the GST amount or a statement that the total includes GST, and the buyer's identity or ABN for sales over $1,000.
The templates here include those fields, but whether your invoice is compliant depends on your registration status and what you are selling. If you are unsure, the ATO publishes clear guidance and a registered BAS agent can confirm it for your situation. Our GST calculator handles the arithmetic.
Are my files uploaded anywhere?
No. The file tools process everything in your browser using JavaScript. Your document never leaves your device, which is why they keep working if you disconnect from the internet after the page has loaded.
Do I need to create an account?
No account, no email and no payment. Every tool on this page works immediately.
Is there a file size limit?
There is no limit we impose, but there is a practical one set by your device's memory. Very large files may be slow or fail on an older phone, since the work happens locally rather than on a server.
Will my work be saved if I close the tab?
No. Nothing is stored between visits, so download your result before you navigate away or refresh.
Can I use the invoice templates for my business?
Yes, and they include the fields a tax invoice normally requires. Whether a particular invoice is compliant depends on your GST registration and what you are selling, so check the ATO guidance or ask a registered BAS agent if you are unsure.
