Your drawing and fonts stay in your browser.

What happens to a file

When you choose an SVG, your browser reads it into a dedicated local Web Worker. If the SVG needs an exact font, the TTF, OTF, WOFF, or WOFF2 file you choose is copied to that worker for the current conversion. The engine shapes text, creates preview geometry, and writes the DXF locally. The conversion flow does not upload SVG or font bytes to svgtodxf.app servers.

Data not sent during conversion

• SVG or DXF file bytes;
• SVG or font file names, font bytes, font families, glyphs, or source text;
• embedded element IDs;
• preview geometry, path coordinates, or exact artwork bounds;
• raw parser errors containing source XML.

Storage in the browser

The free converter does not persist source files, selected fonts, output files, or extracted geometry in browser storage. Font bytes are held only for the current SVG and are discarded when you replace or cancel the file, close the tab or side panel, unmount the converter, or reload the page. A temporary object URL used for download is revoked after the browser starts the download.

On the website, Cut Preflight can keep one workshop profile when you choose Save profile or restore a backup. The profile contains its name, optional shop name and contact details, preferred units, machine bed dimensions, analysis thresholds, and operation mappings with their source appearance or layer labels. It stays in this browser and is not sent to our servers or analytics.

Opening or analyzing a file does not save it. When you explicitly create or update a Shop job, its parts and revisions can store the source SVG or DXF, explicitly selected fonts, profile snapshot, physical-size and operation decisions, analysis results, metrics, report text, customer reference and preparation details in IndexedDB on this device. Generated preview vertices and Shop DXF bytes are rebuilt and are not persisted. Use the Shop profile controls to download a full local JSON backup, delete saved jobs or the profile, or clear all local Cut Preflight data. Clearing website data in your browser also removes these records.

Chrome extension

The Chrome extension packages its JavaScript, interface fonts, Worker, and WebAssembly engine and can complete SVG and selected-font processing without contacting svgtodxf.app. It requests only Chrome's side panel permission, with no access to the sites you visit. It does not include product analytics, session replay, or the optional SVG feedback upload.

After installation and removal, Chrome may open the extension's welcome or uninstall page on svgtodxf.app. Those are ordinary website visits covered by the website request and cookieless analytics sections below; no SVG, DXF, preview, filename, or extension identifier is added to those URLs.

Extension uninstall feedback

If you choose to answer the uninstall form, we collect the reason you select and any optional message you submit, up to 500 characters. This is sent through cookieless product analytics to help us improve the extension. The form does not attach an SVG, DXF, filename, preview geometry, or extension identifier. You can skip it.

Ordinary website requests

Your browser still requests the page, JavaScript, fonts, Worker, and WebAssembly assets from the site host. Like ordinary web hosting, that delivery may expose network metadata such as IP address, request time, and user agent to the hosting provider. It does not require the contents of your drawing.

Cookieless analytics

The service collects cookieless product analytics to understand how the converter is used and which categories of conversion problems occur.

Analytics does not use cookies, browser storage, persistent person profiles, session replay, automatic click capture, or automatic exception capture. IP addresses are discarded. Analytics does not receive SVG or font file names or contents, font families, glyphs, element IDs or text, coordinates, exact dimensions, preview geometry, generated DXF, or raw error messages. It may receive only coarse actions such as selecting a font file or choosing the built-in fallback.

Optional SVG feedback

After a useful conversion failure, the app may offer a Share this SVG button. No file is sent when you open the confirmation dialog. If you select Send SVG, the SVG is uploaded directly to private Vercel Blob storage for compatibility investigation. The original filename is not included. Feedback is limited to 10 MiB.

Shared SVG files are retained in private Vercel Blob storage until they are manually deleted. Font files are never attached. There is no automated deletion schedule. The application does not retain request IPs for this flow; Vercel hosting logs and infrastructure-level abuse controls may still process network metadata. Send only files you have permission to share.

Security limits

The converter rejects scripts, event handlers, external resources, custom entities, and other SVG features that could make local processing unsafe or ambiguous. SVG, stylesheet, font-size, reconstructed-font, glyph-count, memory, and conversion-time limits help protect the browser from untrusted or excessively complex documents.
