Add your YML file
Drop one or more .yml files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
YML to XML
Restructuring .yml data as .xml changes the serialization without touching the values themselves. Free, private, and validated — the file never leaves your browser.

Restructuring .yml data as .xml changes the serialization without touching the values themselves. .yml is simply the three-letter spelling of the YAML extension — the contents are ordinary YAML in every respect. It became entrenched because early adopters favored terse extensions, and flagship filenames like docker-compose.yml and .travis.yml cemented the habit.
An .xml file contains Extensible Markup Language: angle-bracketed tags you define yourself, arranged in a strictly nested tree. It is a meta-format — RSS feeds, SVG images, and Office documents are all XML underneath. For this route the practical draw is rigorous validation against formal schemas and namespaces support mixing vocabularies safely — balanced against verbose — every element name is written twice, which is worth knowing before you commit a large batch.
Why convert YML to XML?
The practical trigger for this conversion is usually a mismatch: with .yml, mixed extensions across one codebase complicate tooling and glob rules. Switching to .xml buys you rigorous validation against formal schemas, which is why it is the better fit for build and platform configuration (Maven POMs, Android manifests). Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
YML vs XML at a glance
| Aspect | YAML data (.yml) | XML data (.xml) |
|---|---|---|
| Format type | Text-based — characters and structure, so there is no visual quality loss | Text-based — characters and structure, so there is no visual quality loss |
| How it stores data | there is no format difference from .yaml whatsoever; parsers never inspect the extension | well-formedness is binary: one mismatched tag makes the document invalid, and conforming parsers must reject it |
| Strongest at | docker-compose.yml service definitions | build and platform configuration (Maven POMs, Android manifests) |
| Weak spot | mixed extensions across one codebase complicate tooling and glob rules | verbose — every element name is written twice |
Pick XML as the output
Select .xml in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if XML is selectable, the route is real and validated.
Convert on your device
Press Convert. The restructuring is plain local parsing — your data is never posted to a server for processing.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid XML file. Outputs keep the original filename with the .xml extension.
YML to XML questions, answered
Will converting YML to XML lose quality?
There is no visual quality to lose — yml is text-oriented and xml is text-oriented, so the question is structural fidelity. Text, ordering, and basic structure are preserved; complex layout, embedded objects, and styling beyond the target's model are simplified.
Is it private to convert YML files here?
Yes — the .yml file is processed inside your browser tab and never uploaded. The restructuring is plain local parsing — your data is never posted to a server for processing. Close the tab and the file is gone from memory.
Where will the XML file work?
Parsers exist in every programming language, browsers display raw XML as an expandable tree, and dedicated editors validate against schemas as you type. Operating systems treat it as plain text otherwise.
Will the XML file be bigger or smaller than my YML?
It depends on the content: well-formedness is binary: one mismatched tag makes the document invalid, and conforming parsers must reject it. Convert one representative file first and compare before batch-processing a large set.
Can I convert XML back to YML?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .yml → .xml → .yml is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
