Step-by-step guide

LofnLogo

Create a portable guide that connects your finished logo files to the uses you have explicitly approved.

Use this when handing finished logo originals to a client who needs clear choices for tasks, backgrounds and variants. You make the design and suitability decisions; the guide presents them and downloads the supplied files.

Exported Cedar client guide recommending the white logo for slides on a dark background.
Actual exported example: Slides and documents, Dark, Full logo selects the white Cedar original. View full size

Before you start

  • Desktop Google Chrome on Linux; Chrome 152 was verified. Other platforms and mobile browsers are unverified.
  • Extract the ZIP and open LofnLogo.html outside an archive preview. Normal use needs no account, terminal, server or connection.
  • Finished originals that you intend the recipient to access, explicit recommendations and a transfer method that permits local HTML files.

Your first result

  1. Try the Cedar example

    Open LofnLogo.html and choose Try the Cedar example. In the rehearsal, choose Slides and documents → Dark → Full logo. Download PNG should produce a2-cedar-white.png, with the same bytes as the supplied cedar-white.png. The free pack's examples/Client-Logo-Guide.html lets you try this recipient experience without buying.

  2. Create your own handoff

    Choose Create a handoff. Enter the client title, date, designer contact and scope under 1 · Originals. Add PNG, JPG/JPEG, SVG, PDF, AI or EPS files. Check the final download names: originals gain a safe ID prefix, while their bytes stay unchanged.

  3. Group and preview the files

    Select file cards, choose Group selected files as and Apply group. Add a variant when needed. For an opaque SVG/PDF/AI/EPS original, optionally pair an imported PNG/JPEG under Preview only (original unchanged). This previews your chosen raster; it does not convert or inspect the original.

  4. Assign the intended uses

    Open 2 · Recommendations. Select tasks, backgrounds, a variant and a recommended original, then Apply recommendations. Either is its own choice; assign Light and Dark separately where needed. Mark essential combinations required. Missing required recommendations block export.

  5. Rehearse and export

    Under 3 · Rehearse & export, check intended and unsupported choices. Complete the three confirmations for recommendations, original names and scope/contact. Changes reset them. Choose Export client guide and Export text handoff. The HTML contains the originals; HANDOFF.txt lists instructions and filenames but contains no original files.

  6. Save and deliver

    Use Save project and keep the downloaded .lofnlogo.json; there is no autosave. Ask your client to download the HTML fully and open it locally in Chrome. A cloud or email preview may not run it. Reopen the saved project for revisions, review again and send a new export. Earlier guides do not update or revoke automatically. Delete the extracted folder to uninstall, keeping any projects and originals you need.

A worked example

Cedar Bicycle Repair: one explicit recommendation

Input: Six fictional originals, two variants and five assigned uses in the included Cedar project.

  1. Choose Slides and documents, Dark and Full logo.
  2. Download the recommended PNG and compare it with cedar-white.png.
  3. Try Professional print / Either / Full logo, then Professional print / Dark / Symbol.

Expected result: The dark-slides choice downloads the unchanged white original. Print / Either / Full logo selects cedar-print.pdf. Print / Dark / Symbol shows no recommendation and the designer contact. All supplied files remain separately accessible.

1. Assign recommendations in batches

One explicit assignment can cover several selected tasks and backgrounds.

2. Try the exported client view

Exported Cedar guide recommending the white logo for slides on a dark background.
The client chooses a task, background and variant, then downloads your assigned original.

3. Explain an unsupported use

Client guide showing no recommendation for an unmapped logo use and displaying the designer contact.
An unmapped combination gives no recommendation while retaining access to all supplied originals.

Troubleshooting

A required use has no recommendation

Choose Correct recommendations and explicitly assign the intended original before exporting.

The opaque original shows a format badge

Pair an imported raster under Preview only if you want a visual cue. Check the original in its usual application.

An import is refused

Read the displayed error and check format, count, byte and raster-pixel limits. Invalid batches and projects preserve the current project.

The guide does not run in a transfer preview

Download and open it locally. If HTML transfer is prohibited, agree a permitted alternative with the recipient.

Changes disappeared after closing

Reopen the last downloaded project JSON. Save before closing; the unsaved-work reminder is not a backup.

Compatibility & limits

  • Verified in desktop Chrome 152 on Linux. Narrow layout checks do not establish mobile compatibility. Other environments, mail gateways and cloud previewers are unverified.
  • 60 originals maximum; 5,000,000 bytes per file, 25,000,000 combined, and 45,000,000 for each project or recipient HTML. Raster originals up to 16 million pixels. Previews are at most 320 × 200 and do not replace originals.
  • PNG/JPEG are decoded for previews. SVG/PDF/AI/EPS remain opaque original downloads; extension labels do not establish validity, native-app support, safety or print suitability.
  • Four fixed tasks, three distinct backgrounds and up to 12 variants. Either is separate from Light and Dark. Variant renaming/deletion is unavailable in version 1.
  • No autosave, cloud hosting, live updates, remote revocation or password protection. Guides and saved projects contain every supplied original; recipients can access them all.
  • No logo generation, original resizing, color conversion, rights inspection or print certification. Review your recommendations and supplied artwork yourself. Human-client time savings and demand have not been measured.
