What an HDR logo maker does

It takes your existing logo file and produces a version that renders brighter than white on HDR displays while looking identical on everything else. The output is a standard JPEG, so it drops into any workflow that accepts an image. The HDR lives inside the colour management, as a Rec.2100 PQ ICC profile, which is why it passes through LinkedIn's re-encode when Ultra HDR gain maps and HDR PNGs do not.

Superwhite is the HDR logo maker behind the Wiz logo that started the trend, and behind the Taboola, Port, Lusha, DoiT and Prime Security logos that followed it.

Preparing a logo for HDR

  1. Flatten it. JPEG has no alpha channel. Composite the mark onto its final background colour before you upload, or let Superwhite composite a transparent PNG for you.
  2. Make the mark genuinely white. The glow targets near-white values. A wordmark at RGB 245 glows noticeably less than one at 255. Push it to pure white in your design tool if the brand allows it.
  3. Keep contrast high. The effect is the gap between the glowing mark and the non-glowing field. A white mark on navy, black, deep green or brand red reads best.
  4. Export square for logos. LinkedIn serves company logos at 400 × 400. Upload square so LinkedIn has nothing to crop.

Making the HDR version

  1. Drop the logo into Superwhite. The split preview shows the original beside the HDR version, and on an HDR screen the right side is already brighter than this page.
  2. Set the glow threshold. This is the luminance above which pixels are treated as white. Tighten it if any of the background is lifting.
  3. Set the strength. Logos read as lit at 1,000 to 1,600 nits. The full 4,000 nit setting is for a deliberate statement, not a default.
  4. Export. Superwhite writes a JPEG with the PQ profile, flattened near-whites, dithering in PQ space and 4:4:4 chroma at quality 97.
  5. Upload the exported file directly. Do not run it through another editor, a scheduling tool that re-compresses images, or LinkedIn's crop and filter controls.

For agencies and brand teams

If you are producing HDR logos for more than one brand, the repeat work is where a maker earns its place over a script. Superwhite Pro adds batch export, so a folder of client marks goes through the same settings in one pass, and saved brand presets, so each client's threshold and strength are one click away next month. Pro also lifts the size cap to 3840px for large-format post graphics and event assets. Pro is €9 a month and cancels any time.

For a single brand: Simple at €3 one time covers unlimited exports at 400px, which is the logo and avatar size. Creator at €5 one time covers 1400px for full-width LinkedIn posts and ads.

Frequently asked questions

Can I use a transparent PNG logo?

Yes. JPEG has no alpha channel, so transparent areas are composited onto a background before export. Choose the background colour deliberately, because the contrast between it and the glowing mark is the effect.

What size should an HDR LinkedIn logo be?

400 by 400 pixels, square. That is what LinkedIn serves for company logos and it means LinkedIn has no reason to resize or crop, so the file comes through its re-encode almost untouched. Simple covers this size.

Does the HDR logo maker work for post images and ads too?

Yes. Post and ad creative is 1200 by 627 on LinkedIn, which needs the Creator tier at 1400px. Sponsored Content keeps the ICC profile, so paid placements glow as well as organic ones.

Can I process many logos at once?

Batch export is in Superwhite Pro along with saved brand presets, so an agency can run a set of client logos through fixed settings in one pass and repeat it next month with one click.

Will the logo look broken on non-HDR screens?

No. On an SDR display, or with HDR switched off, the file renders as a normal logo. That is the point of carrying the HDR inside the colour profile rather than in the pixel values.

Is Superwhite an HDR logo maker for Instagram?

No. Instagram and other Meta surfaces need Ultra HDR gain map JPEGs, a different format from the ICC-profile JPEG that survives LinkedIn. Superwhite is built for the LinkedIn pipeline.
