Terms of Service

Last updated: 2026-09-23

These terms govern your use of the ImageToLine website and its browser-based image conversion tools. By using the site you agree to these terms. They are deliberately short on legalese and long on plain statements, because the service itself is simple: free tools that run in your browser.

Using the tools

ImageToLine provides free, browser-based image conversion tools: an image to line art converter, a photo to coloring page maker, a photo to line drawing converter, a photo to sketch tool, and a photo to outline extractor. You may use them for personal, educational, and commercial projects at no cost. No account is required, no watermark is applied to exports, and there is no quota on the number of conversions.

You are responsible for holding the rights to any photo you process. If you convert a photo you took, you already hold those rights. If you convert someone else's photo, you need their permission first — the same rule that applies to publishing the photo itself.

Your content and outputs

Your images never leave your device; see the privacy policy for the technical detail. The converted outputs you download belong to you. They are generated from your own source images by an automatic process on your machine, and we claim no license, ownership, or usage right over either your inputs or your outputs. You may sell, publish, modify, and distribute your converted files without asking us.

Acceptable use

Do not use the tools to process images you have no right to use, to create material that is misleading, defamatory, or unlawful in your jurisdiction, or to infringe the rights of others — including copyright, trademark, privacy, and publicity rights. Do not attempt to disrupt the operation of the site or circumvent its technical measures. Automated bulk scraping of the site's pages is not permitted; converting images through the tools is exactly what they are for.

Availability and changes

The tools are provided as-is and free of charge. We may add, change, suspend, or discontinue any part of the service at any time — for example, adjusting presets, adding tools, or changing interface elements. Because processing runs in your browser, a version of the site you have already loaded continues to work in that session even if the online site changes, but we do not promise uninterrupted availability of any page.

Quality of results

Conversion quality depends on the source photo: contrast, lighting, subject, and resolution all matter. A soft, low-contrast photo will produce a different result than a sharp, well-lit one, and the sliders exist precisely so you can tune each result. The examples on every tool page show unedited default outputs so you can judge the expected quality before uploading anything. We work continuously on the engine, but we do not guarantee that every photo converts to a usable result.

No warranty

The tools and their outputs are provided without warranty of any kind, express or implied, including fitness for a particular purpose. To the maximum extent permitted by law, we are not liable for any damages arising from the use of the service or its results — including lost profits, lost data, or business interruption — however caused. This does not affect liability that cannot be excluded by law, such as liability for intent or gross negligence where applicable.

Third-party content and links

Tool pages cite external references such as Wikipedia articles for definitions. These links lead to third-party sites we do not control; following them is your choice, and their content and terms are their own. The site otherwise embeds no third-party image services.

Changes to these terms

We may update these terms as the service evolves. The updated date at the top of the page changes with every revision. Continued use after an update means you accept the revised terms. If a change is material — new fees, new usage restrictions — we will mark it clearly at the top of this page before it takes effect.

Governing law

To the extent a governing law must apply, these terms are governed by the law of the operator's place of establishment, without prejudice to mandatory consumer protection rights of your place of residence.

Intellectual property of the site

While your inputs and outputs belong entirely to you, the site itself — the conversion engine, page design, example images, and text — is the property of the ImageToLine team and protected by copyright. You may link to any page freely. You may not republish the site's pages, engine code, or example images as your own product or in a competing converter without written permission. The Wikipedia quotations on tool pages are cited excerpts used for reference, and remain subject to their own licenses, which permit such quotation with attribution.

Using outputs commercially

Three common cases, answered plainly. Worksheets and teaching materials: yes — outputs you generate are yours, including for paid classroom materials. Physical goods (stencils, coloring books, merch): yes, with the same responsibility that your source photo rights are in order. Reselling the converted output as-is as stock line art in bulk: technically yours under these terms, but note that quality varies per photo, and misrepresenting generated output as hand-drawn artwork may raise issues with marketplaces and buyers independent of these terms.

Severability and entire agreement

If any provision of these terms is found unenforceable, the remaining provisions stay in force, and the unenforceable provision is replaced by the closest enforceable intent. These terms, together with the privacy policy, form the entire agreement between you and the service regarding the tools.

Contact

Questions about these terms are welcome; the contact page lists the current feedback channels and what to include so we can answer quickly.

Language note

These terms exist in an English and a German version. Both are authored together and carry the same intent; if a court ever found a divergence in meaning, the English version is the reference text, without prejudice to mandatory consumer rights under the law of your residence.
