Make something from scratch
Tools where you are not converting a file, you are producing one.
- Make a barcodeType a number and the bars appear. Code 128 for anything you invent yourself, EAN-13 or UPC-A for a registered retail number.
- See what a balance grows intoSet a starting sum, what you add each month, a rate and a term. The projected balance redraws as you change any of them.
- Make an invoiceFill in who you are, who owes you money, and what the work was. The invoice prices itself beside the form, ready to download and send.
- Work out a loan paymentPut in the amount, the rate and how long you have. The payment and what it costs you over the term appear as you type.
- Work out a percentageChoose the question you actually have. The answer and the working behind it redraw as you type.
- Make a printable calendarPick a month and a full grid appears, measured to fill the sheet with the biggest day squares the paper allows.
- Make a QR codeType a link and the code appears. It is generated in this tab, so whatever you encode stays on your machine.
- Convert a time between time zonesGive it a date, a time and a zone. The same instant appears on every other clock you ask for, with the offset that applied on that date rather than the one that applies today.
About these tools
Everything else on this site takes a document you already have and changes it. These start from nothing: a form, a few choices, and a finished file at the end. That difference shows up in the interface, because there is no upload step and nothing to wait for before the controls become useful.
So they behave like a document rather than a job queue. What you are making is drawn as you type and redrawn when you change your mind, and the download button hands you the thing already on screen. There is no submit, no preview step to click through, and no moment where you find out that a field you filled in twenty seconds ago was wrong.
The output is a real file with no strings on it. A code or a document produced here contains what you put in it, not a link back to a service that has to stay alive and paid for. That distinction matters most for anything you print, because paper outlives subscriptions.
