The honest version
Browser-based tools: nothing you type or open leaves this page
“How can you compress an image without uploading it?” is the question we get most. The answer is that these are client-side tools: whether you paste JSON, choose a PDF or drag a colour slider, the code arrived with the page and runs on your machine. There is no upload step because there is no server to upload to.
The code
Arrives once, with the page
Opening a tool downloads its code the same way it downloads the text you are reading. From then on the tool is software running in your tab — it keeps working even if you lose your connection.
Your input
Stays inside the tab
Typed text, a chosen file, a picked colour — all of it is held in your browser's memory and read only by the code already on the page. None of it is sent anywhere, so none of it can be logged, cached or leaked.
The result
Is yours, and then it is gone
Copy it or download it. Close the tab and the input and the result are dropped from memory together. Nothing was written to a server, so there is nothing to delete later.
Takes a file
The picker grants read permission; the file is decoded in memory and re-encoded by your own device.
Image Compressor · Merge PDF
Takes text you paste
The text never leaves the field. Parsing, formatting and comparison all happen in the tab.
JSON Formatter · Text Diff
Generates something
Values are calculated from what you set. No input is collected at all.
Colour Wheel · QR Code Generator
Calls an AI model
The one exception, and it is labelled on the tool itself: your prompt is sent to the model provider to be answered.

Questions
Frequently asked questions
Are these online tools really free?
Yes. All 200+ tools are free to use with no account, no trial, no credits and no watermark on anything you download. There is no paid tier holding features back.
Do I need to sign up or install anything?
No. Every tool opens and works straight away in your browser. Nothing is installed, and there is no registration step — bookmark the tool you use most and go straight to it next time.
Are my files uploaded to a server?
No. These are client-side tools: choosing a file only gives the page permission to read it, and the processing happens in your own browser using code that arrived with the page. Files are dropped from memory when you close the tab. The one exception is the AI writing tools, which send your prompt to the model provider — that is labelled on each of those tools.
Is there a file size or usage limit?
There is no daily limit and no per-file cap set by us. The practical ceiling is your own device: very large files use more memory, so a phone will handle less than a desktop.
Do the tools work offline?
Once a tool page has loaded it keeps working without a connection, because the code is already in your browser. You will need to be online to load a different tool.
Can I request a new tool?
Yes. Send the request through the contact page and it will be weighed against the other suggestions for the next round of tools.
