Don't take our word for it — turn off your Wi-Fi. Docexp keeps working. A site that runs with the network off cannot be uploading your files anywhere.
Make your file fit what the form is asking for
Exact pixel size, an exact KB range — including the minimum, which is what actually gets uploads rejected and which almost every other tool ignores. Plus 115 free tools to merge, compress, and convert PDFs, photos, and documents. All in your browser; nothing is ever uploaded.

Test a regular expression against sample text and see the matches.
Writing a regular expression is a loop of guess, run, and squint at what matched. This shortens the loop: type the pattern, paste some sample text, and see the matches highlighted straight away instead of re-running a script each time.
How Regex tester works
- Enter or paste your text or values.
- It's processed instantly on your device as you type.
- Copy or download the result.
Good to know: It uses the browser's own JavaScript regex engine, so what matches here is exactly what will match in JavaScript. That also means JS syntax specifically — PCRE, Python, and Go each differ in the corners (lookbehind, named groups, escapes), so don't assume a pattern transfers unchanged.
