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.
Good to know
Keep the original until you’re happy.
Open the finished image once before you send or upload it. Check the crop, sharpness and file size at normal viewing size, not only while zoomed in.
Changing format does not magically improve quality. Keep the original file until you know the converted version works in the app or service you need.
In plain English
You do not need to be an expert.
If you are helping someone who does not work with images every day, the destination matters more than the jargon: email, print, a website, an ID form or social media.
For most image jobs, start with where the image is going: email, print, a website, an ID form or a social platform.
File size & formats
Big images use more memory than their file size suggests.
What can I use?
JPG, PNG and WebP are the safest choices. Other image formats work when your browser can decode them.
Is there a size limit?
There is no extra OutMonkey upload-size cap in the browser interface. Very high-resolution images can still hit your browser or device memory limit, especially when enlarging them.
If the file is huge
If an enormous image will not process, use a smaller copy or reduce its pixel dimensions first. Keep the original untouched.
