FAQs

How do I reduce the size of an email signature image?

Resize it to the dimensions actually required by the signature, choose a suitable format and quality, then compare the file size before downloading.

What dimensions should an email signature image use?

There is no single size for every signature. Use the pixel width and height required by your email template and keep the original aspect ratio.

Should an email signature image use JPG or PNG?

PNG is useful for logos that need transparency. JPG often suits photographs. Test the exported image in the email clients used by your recipients.

Can Vicoco keep a transparent logo background?

Yes. Choose PNG output and verify the transparent areas in the comparison preview.

Can I prepare high-density signature images?

Yes. You can export larger pixel dimensions and display the image at a smaller size in your signature HTML. Vicoco does not generate the signature HTML.

Can I resize several team signature images together?

Yes, when the source images share a consistent aspect ratio. Apply the same dimensions to the queue and download a ZIP.

Are signature images uploaded to a server?

No. Resizing and compression run locally in the browser.
