What it does

ZeroPNG is your zero-upload privacy-first image toolbox that runs 100% in the browser. Drop images and instantly compress, convert PNG/JPG/WebP/AVIF, and turn iPhone HEIC/HEIF into JPG/PNG. Strip EXIF to remove hidden metadata, crop/resize for perfect dimensions, and add a quick watermark for branding. Batch-process many files, preview results, then download single images or a ZIP, keep working offline after first load. Fast, Simple, Private - your files never leave your device.

Why I made it: - Photos from iPhones often come in HEIC format, which isn’t broadly supported everywhere. - Existing tools tend to require uploads, compromise privacy, or feel clunky. - I wanted a zero-friction, client-side tool where conversion happens instantly, in your browser, without ever touching a server. Try it - https://www.heicconvert.it - No signup, no tracking, and no data is sent to anyone. What’s…
