Frequently Asked Questions

Everything you need to know about using OmniConvert.

Is OmniConvert completely free to use?
Yes. All tools on OmniConvert are free to use, with no hidden charges, credit card requirements, trials or paid subscription tiers.
Do I need to sign up or create an account?
No registration is required. You can convert, compress, and edit files right away without providing an email address, password, or any personal details.
How are my files handled during conversion?
Files are uploaded only when you start a conversion. They are stored under random names in a private temporary folder, processed, and deleted automatically shortly afterwards — or immediately when you click “Delete files now” or close the tab. A few tools (unit, time, color picker, metadata viewer and PDF reader) run entirely in your browser and never upload anything.
What is the maximum file size supported?
Limits depend on the tool and are shown on each tool page: by default up to 1 GB for video, 300 MB for audio, 200 MB for PDFs, 100 MB for documents and 50 MB for images. Very large or long files may take a while to process.
Will converted files have watermarks?
No. Files processed with OmniConvert are exported without watermarks or branding.
Can I use OmniConvert on mobile devices?
Yes. OmniConvert works in mobile browsers on phones and tablets as well as on desktop computers, so you can convert photos straight from an iPhone, iPad or Android phone.
