Terms of Service

Last updated: September 23, 2026

1. Using HDRLOGO

These Terms cover the HDRLOGO website at hdrlogo.com and the HDRLOGO iOS app. By using HDRLOGO, you agree to these Terms. If you do not agree, please do not use it.

The iOS app is also subject to Apple's Standard End User License Agreement. If these Terms conflict with that agreement for the iOS app, Apple's agreement governs. Nothing in these Terms overrides rights that applicable law gives you.

2. What HDRLOGO does

HDRLOGO creates HDR versions of images using local processing on your device. No account or payment is required.

Features and export formats may differ between the website and the iOS app. On the website, opaque images are exported as HDR gain-map JPEGs; images with transparency are exported as 16-bit PQ PNGs.

The gain-map JPEG includes a standard-dynamic-range base image. The PQ PNG does not, so its appearance in software without suitable HDR support may differ.

3. Permission to use the tool

Individuals and organizations may use HDRLOGO under a non-exclusive license, including for client projects and images they intend to sell or publish, subject to these Terms and any applicable App Store rules.

You may not pass off HDRLOGO itself as your own product, interfere with its operation, or gain unauthorized access to its hosting systems. Third-party open-source components, if included, remain subject to their own licenses.

Your permission to use HDRLOGO may end if you breach these Terms. This does not give us any rights to images you have already processed.

4. Your images and your responsibilities

You retain the rights you have in your source images. HDRLOGO claims no ownership of your images or the exported results, and processing an image does not grant us a license to publish or reuse it.

You are responsible for ensuring that your use of the source image and the result is lawful, whether through ownership, permission, or another lawful basis. Conversion does not remove third-party rights or restrictions that apply to an image.

Images are processed locally, as explained in the Privacy Policy. HDRLOGO does not review or moderate the images you convert.

5. Export and compatibility

Check the result in the application and on the platform where you intend to use it. HDR appearance depends on the file format, display, operating system, viewing app, and available brightness range. Other services may resize, recompress, or convert a file and may remove its HDR information.

HDRLOGO does not guarantee identical appearance across devices or continued HDR support on any third-party platform. Image conversion may also change compression, file size, or metadata.

Keep your source files. HDRLOGO creates a separate output rather than editing the selected source in place. If you choose to replace an existing file when saving, that choice is yours.

6. Availability and changes

HDRLOGO is currently free. The website may change, be interrupted, or be discontinued, and app updates may change available features. There is no service-level commitment or guaranteed support response time.

Local conversion in the installed iOS app does not depend on the website being available. Future compatibility with every device or operating-system version is not guaranteed.

7. Warranty and liability

To the extent permitted by law, HDRLOGO is provided “as is” and “as available,” without express or implied warranties, including warranties of merchantability, fitness for a particular purpose, or non-infringement.

To the fullest extent permitted by law, HDRLOGO's provider is not liable for indirect, incidental, special, or consequential losses, including loss of data, images, profits, or business, arising from use of or inability to use the tool.

Nothing in these Terms excludes liability that cannot lawfully be excluded or limits your mandatory consumer rights. Where a limitation is not permitted in your jurisdiction, it does not apply to you.

8. Changes to these Terms

We may update these Terms and will change the date above when we do. Material changes will be clearly announced on the website or in the app, as appropriate, with an effective date. Where required, we will ask you to accept the updated Terms. Changes will not apply retroactively to disputes that arose before they took effect.
