What Pro users say
Real workflows, bigger files, presets that stick.
I run a small e-commerce shop and convert dozens of product clips into animated WebPs every week. Once I hit the free tier's limits I upgraded, and having a saved library of presets (one for hero banners, one for thumbnails) turned a five-minute fiddly task into a two-click job. Worth it just for the time back.
MarcusPro userWhat sold me on Pro wasn't a single killer feature, it was not having to redo my settings every time. I convert a lot of animation reference clips and having presets saved to my account means I open LightBox, pick a preset, upload, done. The frame-picker for choosing a poster frame is also just genuinely well built.
DevonPro userI batch-convert conference recordings into WebM clips for our internal wiki every week. Pro's higher size caps mean I'm not fighting the tool on longer footage anymore, and the saved presets keep the output consistent without me re-checking settings every time.
PriyaPro userUpgraded mainly for the account library so I could stop re-downloading files I'd already converted. Turned out to be handy for versioning too — I keep a couple of quality variants of the same clip side by side instead of converting from scratch each time. Only wish is more presets slots, but minor complaint.
