Is this PFX to CER converter free?

Yes, completely free. No registration, no hidden fees. Free users can convert files with Xonvert's full engine.

Why is my converted CER file larger than the original PFX?

File size depends on compression settings and content complexity. Try the Medium quality preset for smaller output, or the file may simply contain data that resists CER compression.

What browsers are supported?

Chrome, Firefox, Safari and Edge (all recent versions). Any browser supporting WebAssembly will work.

Is there a watermark on converted CER files?

No. Free conversions produce clean output with no watermarks. Your CER file is identical to what a paid desktop tool would produce.

Will this converter work on Chromebook?

Yes! Chromebooks run Chrome browser, which fully supports Xonvert's WebAssembly-based conversion engine.

Will I lose quality converting PFX to CER?

No — CER preserves quality losslessly. Your output will be faithful to the original.

Does this tool support drag and drop?

Absolutely. Drag files directly from your file manager onto the converter area. You can also click to browse, or paste from clipboard.
