Use casesKeep files private: local processing & the validation gate
A hands-on tour of how Novus Convert keeps files private: active conversion runs in your browser memory on your device, signatures rather than filenames decide handling, and a validation gate withholds every download until the real result passes a signature, container, or decodability check.
9 min · BeginnerStart
Formats & batchConvert images between PNG, JPG, WEBP, and AVIF
Pick the right raster output for every image job in Novus Convert: PNG or WebP when transparency matters, JPG for maximum compatibility, WebP or AVIF for lean web delivery — then confirm the validated result actually looks right before you use it.
9 min · BeginnerStart
Use casesTroubleshoot failed conversions in Novus Convert
A calm, ordered way through any failed row: read what the validation gate is telling you, unmask renamed and unsupported files, work within the size limits, split batches that strain browser memory, and file a bug report that actually helps.
