Why it matters
Early validation
Unsupported file types, sizes or media combinations are flagged before entering the publish queue.
Target-aware checks
The same file is evaluated separately for every selected platform; validity for one target is not assumed for another.
Fewer publish-time surprises
Fixable format problems appear while content is prepared, rather than surfacing at publish time.
How it works
- 1
Upload the media
File type, size and readability checks begin as soon as an image or video is uploaded.
- 2
Choose publishing targets
Selected accounts and post format define the validation context, with platform-specific rules applied separately.
- 3
Fix the issue at the source
Invalid media is identified per target. Replace the file or update the target and run the check again.
- 4
Schedule validated content
Content that passes validation can be published immediately or scheduled for a future slot.
Frequently asked questions
Does every platform accept the same format?
No. Validation varies by platform, post type and media combination.
Can a file be valid for one platform and invalid for another?
Yes. Postid evaluates each target against its own rules and shows the issue on the affected platform target.
Does validation replace the platform publish response?
No. Pre-validation catches known, fixable issues early; final acceptance is always determined by the platform response.
