Your images stay on your device
WebP validation, decoding, previews and JPG encoding happen in this browser. Images, filenames, file sizes, dimensions and conversion results are not uploaded or written to website storage. Temporary browser memory and preview URLs are released when cleared, replaced or when this page closes. Browser caching and downloaded files are controlled by your browser.
Anonymous analytics
Analytics is disabled in local and staging versions. When fully configured on this tool’s exact production hostname, Umami Cloud counts visits and fixed action categories. We send the website ID, fixed hostname and a page category (home, privacy or unknown page). Events describe a conversion outcome, a download/open attempt or where an optional support entry was opened and whether its button loaded.
We do not send image content, names, sizes, dimensions, amounts, payment status, query strings, fragments or raw referrer/UTM data. Umami and its network infrastructure can process request metadata such as your IP address and browser information to operate their service; this is not a promise of network anonymity. Visits are grouped under a shared website ID and separated by hostname.
Your choice
Use Analytics settings in the footer to turn analytics off. This preference is stored in localStorage under webp-to-jpg.analytics.consent.v1. Re-enabling requires a reload. QA visits starting with ?qa=1 store a tab-specific exclusion in sessionStorage under webp-to-jpg.analytics.qa.v1. Removing the parameter does not remove this exclusion. Storage failures keep analytics off. These small settings never contain an image.
Optional, one-time support
Buy me a coffee opens a voluntary one-time tip. The PayPal SDK loads only after you open that dialog. PayPal handles payment and may make third-party requests or use its own storage under its policies. An external fallback opens PayPal in a new tab only when you click it. The author’s payment button is also used by InvisiChar; the checkout may show that name. No image or conversion data is passed to PayPal. Using this tool never requires payment.
Other requests
Site assets and fonts are served with this site. Hosting and CDN providers receive normal requests and may keep operational logs. This version includes no advertising, session recording or additional RUM analytics. Third-party privacy terms apply to their services.
