Drop one or more .atom 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.
ATOM to RSS
Converting a .atom font to .rss repackages the same glyphs and metrics for a different delivery target. Free, private, and validated — the file never leaves your browser.

Converting a .atom font to .rss repackages the same glyphs and metrics for a different delivery target. An .atom file is an Atom feed: the IETF-standardised syndication format, structured as a feed element containing entries, each with a globally unique id, a title, a timestamp and either content or a link to it. It was designed to fix the ambiguities RSS had frozen in place.
A .rss file is an RSS feed: an XML document listing a channel's recent items, each with a title, link, description and publication date, so that a reader can poll one URL instead of visiting a site. It is the format that made subscribing to a website a thing you could do. For this route the practical draw is the most widely supported syndication format by a wide margin and a frozen specification means decades-old files still work — balanced against rFC 822 dates are an ongoing source of quiet parsing failures, which is worth knowing before you commit a large batch.
Why convert ATOM to RSS?
The practical trigger for this conversion is usually a mismatch: with .atom, less widely supported than RSS despite being the better specification. Switching to .rss buys you the most widely supported syndication format by a wide margin, which is why it is the better fit for publishing a blog or news feed for subscribers. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
ATOM vs RSS at a glance
| Aspect | Atom feed (.atom) | RSS feed (.rss) |
|---|---|---|
| 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 | every entry requires a globally unique id, which removes RSS's ambiguity about what identifies an item | a single <channel> holds metadata and a flat sequence of <item> elements — there is no nesting |
| Strongest at | publishing a feed where content type and identity must be unambiguous | publishing a blog or news feed for subscribers |
| Weak spot | less widely supported than RSS despite being the better specification | rFC 822 dates are an ongoing source of quiet parsing failures |
| Metadata | feed and entry fields — id, title, updated timestamp, link and summary — are preserved. Typed content markup and namespaced extensions are not carried into simpler targets | channel and item fields — title, link, description, publication date and guid — are preserved. Namespaced extensions such as podcast tags are not carried across |
Pick RSS as the output
Select .rss in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if RSS is selectable, the route is real and validated.
Convert on your device
Press Convert. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid RSS file. Outputs keep the original filename with the .rss extension.
ATOM to RSS questions, answered
Will converting ATOM to RSS lose quality?
There is no visual quality to lose — atom is text-oriented and rss 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 ATOM files here?
Yes — the .atom file is processed inside your browser tab and never uploaded. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip. Close the tab and the file is gone from memory.
Where will the RSS file work?
Read by every feed reader, every podcast client and most CMS platforms. Browsers dropped their built-in feed viewers years ago, so a feed opened directly usually shows raw XML. Novus Convert parses it locally and converts to Atom and JSON Feed.
Will the RSS file be bigger or smaller than my ATOM?
It depends on the content: a single <channel> holds metadata and a flat sequence of <item> elements — there is no nesting. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my ATOM file?
In .atom, feed and entry fields — id, title, updated timestamp, link and summary — are preserved. Typed content markup and namespaced extensions are not carried into simpler targets. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Can I convert RSS back to ATOM?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .atom → .rss → .atom is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
