Benefits
Private by design
Your file stays on your device while XML Minifier works. XML Minifier never sends it to a server, so confidential work stays confidential.
Instant results
XML Minifier finishes most jobs in under a second because the work happens on your own hardware.
No signup, no limits
Use XML Minifier as many times as you want. XML Minifier asks for no account, adds no watermark and keeps no paid tier gating the output.
Works offline
Once the page has loaded, XML Minifier keeps working without a connection, which helps on flights and locked-down networks.
Who it is for

Developers use XML Minifier to debug and ship faster without installing software: minify XML on a shared or locked-down machine.
For freelancers
XML Minifier helps freelancers send client deliverables quickly, since your file never leaves the laptop it was created on.
For support teams

How it works
XML Minifier loads your file into memory, applies the change you requested to the underlying data rather than to a screenshot of it, and writes a fresh copy for download. Your original stays untouched on disk, and every step of XML Minifier happens inside your browser sandbox.
Frequently asked questions
Is XML Minifier free to use?
Yes. XML Minifier is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does XML Minifier upload your file to a server?
No. XML Minifier processes your file inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.
Is there a file size limit?
The practical ceiling is your device's available memory rather than a server quota. Files up to roughly 100 MB work comfortably on a typical laptop in XML Minifier.
Do I need to install anything to use XML Minifier?
No installation is needed. XML Minifier runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use XML Minifier on a phone or tablet?
Yes. The XML Minifier interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.
What happens to your file when I close the tab?
It is discarded. XML Minifier keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
