TOOLNIVO / SUPPORT
Help & contact
Help with ToolNivo tools, thumbnail previews, file conversions, downloads and current contact arrangements.
Need help using a tool?
Start with the tool's instructions and FAQ, or browse our guide library. Check supported input formats and the visible error message.
Thumbnail downloads
The thumbnail downloader needs no API key. Use a direct video link, then select an available image size.
- Check an incomplete video URL
- Why the largest resolution may be missing
- Save with the browser fallback
Direct contact availability
A dedicated public contact address has not yet been configured. Direct email support and a message form are not currently available.
We do not ask you to submit personal information or API keys through this page. For a future technical report, useful details include the page URL, browser, approximate time, and visible error text. Omit credentials and private information.
Corrections and privacy questions
Read our editorial policy for how the guides were prepared and our privacy policy for the current data flow. Where an issue concerns YouTube's handling of image requests or the hosting provider’s account records, their own support and privacy channels apply.
Background removal help
Start with a clear JPG, PNG or WebP. Read the status message if loading fails, try a recent full browser and keep the tab visible during processing. For edge, export and device questions, browse our 40 background removal guides. Photos are processed locally; we do not have a server copy to retrieve after you close the page.
File to PDF help
Use a supported text file, image or unencrypted .docx under 10 MB. Older .doc files must first be saved as DOCX. If conversion fails, try a smaller file or export directly from your word processor. For layout questions, see the converter FAQ.
