Your signature details01 / EDIT
English names and company names are entered manually. No automatic translation.
Nothing is saved unless you choose Save. Image previews request the image URL from its host.
Unsafe tags, attributes and URLs are removed. Flex/grid layouts are simplified. This cannot fix mail-app bugs or inaccessible image servers.
Repaired HTML
Uses your selected template and color. Downloads one HTML document containing full, reply and mobile signatures in both languages for each employee. No account deployment.

Your signature is ready. Make it yours.
2. Review the warnings
The checker flags common code risks, not a guaranteed compatibility score. An image can still be blocked by the recipient or unavailable at its host.
3. Test before sending
Send yourself a message and open it on desktop and mobile. Check links, image visibility, dark mode and replies in your actual mail apps.
Installation guide
Why did my logo disappear?
Mail apps may block remote images, or the host may require sign-in. Use a publicly accessible HTTPS image URL, set width and height, and keep meaningful alt text. Local files and data URLs are unsuitable for reliable pasted signatures.
Does repair guarantee Outlook compatibility?
No. Repair removes unsafe content and simplifies common risky formatting. Outlook versions use different rendering engines. Send an actual test message and verify your particular version.
Where is my information stored?
The tool processes contact details and CSV files in your browser. Device storage is optional and can be cleared. Do not use Save on a shared computer. Remote logo hosts receive image requests. Blogger, Google advertising and other platform services have their own policies.
