Frequently Asked Questions

Common questions about Nik Images Auto Convert

That is precisely what it is built to avoid. Every reference the plugin can reach is rewritten, originals are kept so the whole thing can be rolled back, and the optional rewrite rule catches URLs living outside the database. Back up your database before the first bulk run anyway.

80–85 is visually identical to the original for most photographs. Use the built in test button: it converts five real images from your library in a temporary folder and reports the actual saving without changing anything.

Because converting them would have made them bigger. Small flat colour graphics often compress better as PNG than as WebP, and a photo that was already heavily compressed can grow when re-encoded. WordPress stores a MIME type per thumbnail size, so a mixed set works fine.

Yes, as long as "Keep the original files" was enabled. Nik Images → Restore & tools → Restore all originals puts the files back, restores the attachment records and rewrites your content back to the original filenames.

No. Converted images stay converted. Use the restore button first if that is what you want.

Yes. Page builder data stored as JSON, ACF fields stored as serialized meta and WooCommerce product galleries are all rewritten. Values the plugin cannot rebuild with absolute certainty are deliberately left alone instead of being corrupted.

Yes, if GD has WebP support, which is the case on almost every modern host. The settings screen shows what is available.
