Check a logo SVG for BIMI (your logo next to your emails)
A logo exported from Illustrator is almost always a valid SVG and an invalid BIMI file, for the same few reasons every time. This tool lists them so you can fix each one.
- Runs entirely in your browser
- Works offline
- No upload
- No sign-up
- No watermark
Loading the tool…
How it works
- Drop the SVG, or paste its source.
- Fix each failing check. Most need one small change in the file, or one “convert text to outlines” in your drawing program.
- Check the 32 px preview: that is roughly the size a mailbox actually shows.
Why nothing is uploaded
Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.
Verify it yourself
- Open your browser’s developer tools (F12) and select the Network tab.
- Load your file and run the tool.
- The only requests you will see fetch the tool’s own code — and, for a few heavy tools, their open-source engine from a public CDN — plus one small page-view ping to loreatec.jp (page address and title, nothing more). None of them carry your file.
Frequently asked questions
What is SVG Tiny P/S?
A deliberately small version of the SVG image format, designed to be safe to display inside a mail program. It forbids anything that runs, loads or moves: scripts, links to outside files, animation, filters, gradients, live text. BIMI requires exactly this format, declared with version="1.2" and baseProfile="tiny-ps" on the root element.
Why must text be converted to paths?
Because live text needs a font, and the renderer showing your logo has no way to get yours. Converting to outlines — “Create outlines” in Illustrator, “Object to Path” in Inkscape — makes the letterforms into shapes that render identically anywhere. It also shrinks the file.
My SVG passes here. Will the logo appear in Gmail?
Not from this alone. BIMI also needs a strict DMARC policy on your domain (quarantine or reject, pct=100) and a DNS record called default._bimi that points to the file over https. Gmail and Apple Mail additionally require a paid certificate (a VMC, or a CMC) from an approved authority — a VMC needs a registered trademark and costs money each year — while some mailboxes such as Yahoo have shown the logo from the record alone. This page checks the file; the domain security tool on this site checks the DNS side.
Is BIMI worth doing?
It is the last step, not a first one, and it only pays off once the authentication underneath it is already right — which is the part that actually improves delivery. Treat the logo as the reward for finishing DMARC, not as a way to get there.
