ShortSync alternative for editors: twice the free uploads, the file untouched, $9 after
PostWire does what editors use ShortSync for, uploading an edit to TikTok from a PC through the official API without the app's recompression, and goes further: 10 free uploads a month instead of 5, 1 GB files on the $9 plan instead of plans from €14.99, and the same file to YouTube Shorts and Instagram Reels in the same click.

What ShortSync does well, and where PostWire goes further
ShortSync is built for short vertical video and does that cleanly: official TikTok login, 16 platforms, scheduling, bulk uploading and API access already on its free plan, unlimited uploads on the €14.99 Creator plan, plus an inbox for comments. If you post five edits a month and want them on many networks at once, it is a fine choice.
PostWire starts from the same guarantee, your file goes up through TikTok's own Content Posting API exactly as you exported it, and adds what editors asked for once their account started to grow:
Twice the free uploads. 10 posts a month on Free, files up to 100 MB, no card. Enough for the two or three edits a week most editors post while they test an account.
A cheaper paid plan with bigger files. Starter is $9 a month with 1 GB per file, so a 3-minute 1080p60 export at 25 Mbps still goes up as is. 1,000 posts a month, 3 brands, 14-day refund.
Shorts and Reels in the same click, with a caption per network. Connect YouTube and Instagram once and the same upload goes to all three; the AI writes a hook-first TikTok caption, a shorter Reels caption and a YouTube title. Free sends each post to 2 networks; Starter to all.
Post as private first. Pick "only me" on the upload, watch it in the TikTok app, then switch it to everyone. Many editors check their first upload this way.
Scheduling on every plan, an API, an MCP server and an n8n node. Useful the day you want a queue, or a script that posts for you.
A creator program that pays editors. Show your upload method in a video and PostWire gives you 30 days of Pro and 30 % of every payment from the viewers who sign up through you, for 12 months.

Switching takes two minutes
Open the dashboard, type your email and press Create my free account. No password, no card.
Press Connect next to TikTok and sign in on TikTok itself. PostWire never sees your password; TikTok's own approval of the PostWire app covers you.
Drop the MP4 you exported (1080x1920, 60 fps if your edit is 60 fps, H.264 High at 10 to 25 Mbps), write the caption, choose who can view it, and press Publish.
Open the post in the TikTok app. It is the file you exported, frame for frame. The full method is on the upload method page.
Already posting about your upload method? Get paid for it
Editors who make a short video of their settings, the upload and the 60 fps result get 30 days of Pro on the spot and 30 % of every payment from the viewers who sign up through their link, for 12 months.
No. Your browser uploads it in chunks to PostWire's storage, PostWire streams those exact bytes to TikTok's Content Posting API, and the copy is deleted the day after the post goes out.
Will the post say "posted via PostWire"?
No label is added to your video or caption.
Is 100 MB enough on Free?
It covers a 1080p60 edit of about a minute at 12 Mbps. Longer or heavier exports fit in Starter's 1 GB per file.
Can I keep ShortSync and try PostWire on the side?
Yes. Both connect through TikTok's official login and neither one removes the other. Post one edit with each and compare them in the app.
What does Starter add for $9?
1,000 posts a month, 1 GB files, every network per post, 3 brands, AI captions, 14-day refund. Cancel from the dashboard in one click.
