Frequently asked questions
Is the PUB to DNG converter free?
Yes. This free online converter has no limits and no watermarks.
Are my files uploaded to a server?

Can I convert multiple PUB files at once?

Is PUB to DNG processed on my device?
Yes. XConverters handles files locally in the browser and does not transfer them to our servers.
Will DNG reduce PUB quality?
This DNG path keeps pixel data intact depending on your settings.
Does DNG keep transparency from PUB?
Neither side relies on alpha in this conversion path.
Do I need software installed for PUB to DNG?
No. Open the tool in a modern browser, pick PUB, and download DNG after processing.
How large can my PUB file be?
Limits depend on device RAM and the browser. Test one large file before converting a full batch.
What this conversion does
This path turns PUB (.pub) files into DNG (.dng) inside your browser. XConverters reads pixels locally and re-encodes them in the target format without sending your file elsewhere.
DNG output is lossless and fits uncompressed camera originals before editing.
When to use it
You need DNG for uncompressed camera originals before editing while the source is PUB.
You need precise DNG for print, archive, or further editing.
You want an instant DNG preview before sharing or publishing.
Advantages
Convert PUB → DNG locally without waiting in a remote queue.
DNG keeps fine detail for print and archival use.
Batch a handful of PUB files with the same settings.
Limitations
Very large PUB files can exhaust browser memory before conversion finishes.
Quality considerations
Avoid re-saving PUB through multiple lossy formats.
Compare size and sharpness before replacing the original.
Keep the original PUB copy before committing to DNG.
Best practices
Name outputs with the correct .dng extension to avoid viewer errors.
Keep a PUB master for future edits.
Use identical quality settings across a batch for consistent results.
Privacy
Your files never leave your device when you use PUB → DNG conversion on XConverters. No account is required and we do not retain copies of the images or documents you process.
That local-first model suits personal photos, work documents, and sensitive RAW files you prefer to keep offline.
Browser processing
XConverters runs PUB → DNG conversion entirely inside your browser. Files are decoded locally, pixel data flows through Canvas or WebAssembly where needed, and the finished file is encoded on your device.
No remote copy is created during processing. Temporary data clears when you close the tab or refresh unless you download the result yourself.
Common mistakes
Assuming DNG is always smaller than PUB — lossless PNG/TIFF output can be larger.
Re-converting the same PUB through DNG while lowering quality each time.
