Usage & privacy

Using the tools

Use the latest desktop Chrome or Edge. This free beta does not require an account. Mobile, Safari and other browsers are not supported for this beta.

Batch Recolor starts with one solid-color product image and one product-wide mask. Check the mask, correct edges with the editing tools, then create up to 50 colorways. Fine edges, similar backgrounds and large dark-to-light changes may need manual correction.

Flat Fill Studio starts with a technical flat. Check its Base, add color areas if needed, then apply solid colors or patterns and create colorways. Review each tool's Image guidelines before choosing an image.

• Batch: PNG/JPG up to 20 MB. Oversized images are reduced to fit a working limit of 1820 pixels on the long side and 2,484,300 pixels in total.
• Flat: PNG/JPG up to 20 MB, or self-contained SVG up to 2 MB. Patterns: opaque PNG/JPG/WebP up to 10 MB and 4096 × 4096 pixels.

Review the exported results before using them. Automatic masks and color changes may need adjustment; results are not guaranteed to be ready for final product listings.

Downloads & recovery

Batch's automatic masking downloads about 100 MB on first use and needs an internet connection. Your browser may reuse the model on later visits. Clearing site data, private browsing or unavailable browser storage can require another download. The first mask in a new browser session can still take longer while the model starts.

There is no project saving or autosave. A cached model is not a saved project. Download your PNGs or ZIP before refreshing, closing the tab, switching tools or starting over.

If model loading fails, check your connection and retry using the controls shown. If a download fails, keep the workspace open, check your browser's download permissions and available disk space, then retry. If ZIP download fails, try individual PNGs where available. Save any available results before considering a refresh.

Privacy & storage

Your source images, masks, edits and exports are processed in your browser. These tools do not upload your images to a processing server or save them on a server.

Loading the website makes requests to Cloudflare. Batch also requests model files from Hugging Face. These requests expose ordinary connection information, such as your IP address, to those providers; they do not contain your source images.

The browser may store the masking model and interface preferences, such as language and the Structure panel setting. This storage does not save your artwork, colorways or workspace.

We collect daily totals for tool entry, work preparation, result creation, download handoff, feedback-link opening and predefined error categories. Events contain only the tool, release, a public channel code, test mode and coarse preparation-time category. They do not contain images, filenames, color names, email addresses or a persistent user identifier. These are activity counts, not counts of individual people.

A public channel code and test mode may remain in this tab's session storage. We respect Do Not Track and Global Privacy Control. Cloudflare receives the events and processes connection information; our application does not store IP addresses or raw requests. The aggregate database is hosted in Cloudflare's Asia-Pacific region, and network processing may occur internationally. See Cloudflare's privacy policy. We may retain aggregated counts to evaluate and improve the beta. Statistics failures do not prevent editing or downloading. Contact information and feedback deletion requests are described below.

Contact & feedback

Give feedback in our short Tally survey. Your workspace stays open in this tab.

Survey responses are sent to Tally and reviewed by Liteworkroom to improve the beta. An email address is optional. Do not include private images or sensitive information. See Tally's privacy notice.

After an export is prepared, we may invite you to share feedback. We store a separate local reminder preference for each tool and may ask again only when you export after three days. Choose “Already shared feedback” to stop automatic invitations for that tool during this beta in this browser; the Feedback links remain available. This reminder preference saves your choice, not a verified survey submission. Clearing site data, blocked browser storage or using another browser can show the invitation again.

Questions, bug reports or suggestions? Email [email protected].

For a bug report, include the tool name, browser version, what you tried and any error message. Please do not send private images or sensitive information.

The link opens your email app. If it does not open, copy the address into your email service. Nothing is sent automatically.

We will delete original survey responses, including optional email addresses and email notification copies, within 90 days after the beta ends. We may retain anonymous summaries of feedback to guide improvements.
