Add your XML file
Drop one or more .xml 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.
Restructuring .xml data as .yml changes the serialization without touching the values themselves. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Restructuring .xml data as .yml changes the serialization without touching the values themselves. 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.
.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. For this route the practical draw is fully interchangeable with .yaml — a rename is the whole migration and matches the default filenames that many popular tools generate — balanced against mixed extensions across one codebase complicate tooling and glob rules, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .xml, verbose — every element name is written twice. Switching to .yml buys you fully interchangeable with .yaml — a rename is the whole migration, which is why it is the better fit for docker-compose.yml service definitions. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
| Aspect | XML data (.xml) | YAML data (.yml) |
|---|---|---|
| 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 | well-formedness is binary: one mismatched tag makes the document invalid, and conforming parsers must reject it | there is no format difference from .yaml whatsoever; parsers never inspect the extension |
| Strongest at | build and platform configuration (Maven POMs, Android manifests) | docker-compose.yml service definitions |
| Weak spot | verbose — every element name is written twice | mixed extensions across one codebase complicate tooling and glob rules |

Select .yml in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if YML is selectable, the route is real and validated.
Press Convert. The restructuring is plain local parsing — your data is never posted to a server for processing.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid YML file. Outputs keep the original filename with the .yml extension.
There is no visual quality to lose — xml is text-oriented and yml 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.
Yes — the .xml 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.
Anything that reads .yaml reads .yml identically, from language libraries to editor plugins. The only compatibility question is which spelling a given tool looks for by default when discovering config files.
It depends on the content: there is no format difference from .yaml whatsoever; parsers never inspect the extension. Convert one representative file first and compare before batch-processing a large set.
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .xml → .yml → .xml is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
