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.

Pretty-print or minify JSON, with error checking.
Two jobs in one: make unreadable JSON readable, or squeeze readable JSON down for the wire. Paste it in and it's pretty-printed with indentation — or minified to a single line — and if it doesn't parse, it says so rather than failing silently.
How JSON formatter / minifier 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: Because it runs entirely in your browser, it's safe to paste JSON that has real data in it — an API response with a token, a config with credentials. Nothing is uploaded, which is a promise most online JSON formatters can't make.
Common questions
Is it safe to paste JSON containing secrets?
Here, yes — the parsing happens in your browser and nothing is sent anywhere. Be careful with online formatters generally: most POST your input to a server, which is a genuinely bad idea for a payload containing a token or a key.
