Private by design
Files stay with you.
The actual file processing happens in your browser. A small number of advanced tools may load a browser helper library, but OutMonkey does not upload your file to do the job.
How file handling works →Before you finish
A quick check makes a better result.
OutMonkey is built to be simple enough for someone doing this once and useful enough for someone who does it every day.
What this tool is for
Platform file checker
Inspect file size and type before upload. The aim is a useful result without making you learn a full piece of software first.
Good to know
Check it where people will actually see it.
Preview the result at phone size and keep important text, faces and logos away from edges or interface areas that a platform may cover.
A checker tells you what it can measure; it does not replace a final human look. Use the result to make the next decision, not as a guarantee.
In plain English
You do not need to be an expert.
Platform specifications change. Use these sizes and previews as a practical starting point, then check the current upload screen if a platform rejects the file.
Start with the placement, then worry about the exact pixel dimensions.
File size & formats
OutMonkey checks the file; the platform sets the final rule.
What can I use?
Image-based social tools work best with JPG, PNG or WebP. File checkers can inspect the file your browser provides.
Is there a size limit?
OutMonkey does not add a separate upload-size ceiling to these local helpers. The destination platform may have its own size, dimension, duration or format limit.
If the file is huge
If Instagram, an ad manager or another service rejects the result, check that service’s current upload message because platform limits can change.
