Built for serious shorts creators

1

Schedule Shorts automatically

Queue Shorts to publish at the exact date and time you pick via YouTube's official API. Shorts go live on time with title, description, and thumbnail already set.

2

Cross-post to Reels & TikTok

Upload a single 9:16 vertical video and PostLink publishes to YouTube Shorts, Instagram Reels, TikTok, and Facebook Reels simultaneously. No re-exporting, no re-titling.

3

3-minute Shorts support (2026)

YouTube extended Shorts to 3 minutes in 2024. PostLink handles the full 3-minute window — shorter formats also work natively.

4

Thumbnail selection

Pick the exact frame used as your Short thumbnail or upload a custom image. Important for Shorts that also live on your channel homepage.

5

Title, description & tag prep

Write titles up to 100 characters and descriptions up to 5,000 — plus tags — all inside PostLink before scheduling.

6

Batch a full month of Shorts

Upload 30 Shorts in one session. PostLink publishes each at its scheduled slot so you never miss a daily post — even on vacation.

How to schedule Shorts with PostLink

Six steps, under three minutes.

    Write a title (100 chars), description (5,000 chars), and tags. PostLink's character counter prevents cutoff.

Shorts scheduling FAQ

Can you schedule YouTube Shorts in advance?
Yes. YouTube Shorts can be scheduled through tools that use the YouTube Data API. PostLink supports full Shorts scheduling with the 2026 3-minute duration limit, custom thumbnails, and automatic cross-posting to TikTok and Instagram Reels.
How do I schedule a YouTube Short?
Upload a 9:16 vertical video (up to 3 minutes, up to 700MB), add title, description and tags, pick a thumbnail, select any additional platforms for cross-posting, and choose a publish date up to 90 days ahead. PostLink handles the upload automatically.
How long can YouTube Shorts be in 2026?
As of 2024, YouTube Shorts can be up to 3 minutes long (previously 60 seconds). The 3-minute limit is still the 2026 spec. Anything longer than 3 minutes publishes as a regular long-form video, not a Short.
Can I cross-post a YouTube Short to TikTok and Instagram Reels?
Yes. PostLink lets you upload once and distribute the same 9:16 video to YouTube Shorts, Instagram Reels, TikTok, and Facebook Reels simultaneously — each with its own caption if needed.
Does YouTube have native scheduling for Shorts?
YouTube Studio supports scheduling uploads, but the mobile-first Shorts workflow is cumbersome for batch uploads. PostLink treats Shorts as first-class content with a batch calendar view and multi-platform distribution.
What is the maximum file size for a Short on PostLink?
700MB per file, which covers the full 3-minute duration at high quality without compression artifacts.
How far in advance can I schedule YouTube Shorts?
Up to 90 days in advance on the Pro plan.
