Six tools for YouTube creators who upload in hours, not minutes — plan exports, control file size, test thumbnails, convert captions, archive smart, and know what it earns.
Every tool runs in your browser — nothing uploads, nothing tracks your files, no account needed.
Compress any clip to an exact target size — Discord's 10 MB, email's 25 MB, or your own. Copy-paste FFmpeg commands and HandBrake settings.
Realistic earnings by niche RPM — or reverse it: set an income goal and see exactly how many views you need to get there.
See your thumbnail at YouTube's real render sizes — search, sidebar, mobile feed — with file checks against the 2 MB limit.
The right bitrate for 1–3 hour uploads — tuned for static-artwork music videos that don't need live-footage file sizes.
Convert subtitles both directions, instantly, privately. YouTube wants SRT; web players want VTT — keep both from one master.
Your video is live — now shrink the 12 GB master to an archive that's still good enough to re-upload anywhere, and free the drive.
Most creator tools assume short videos: quick exports, small files, disposable masters. Long-form is a different sport. A single lofi mix or ambient session can mean a 10–20 GB export, an hour of uploading, and a hard drive that fills up in months.
VideoPublishKit exists for that workflow. Every tool here is tuned for videos measured in hours — where the right bitrate saves gigabytes, where the thumbnail competes at 168 pixels in a sidebar, and where archiving strategy decides whether your channel scales or your storage does.
Calculators run on math, converters run in your browser. Your files never touch a server.
Open a tool, get your answer, get back to creating. Every tool is free.
Static artwork and lofi loops compress differently than live footage — our recommendations know that.
Every result copies as paste-ready settings for Premiere, DaVinci Resolve, and HandBrake.
