InBrowserConvert

InBrowserConvert is a free file converter that runs entirely in your web browser. Unlike most online converters, it never uploads your files to a server: every conversion happens on your own device, so your photos and documents stay private. No daily caps, no queue, no account.

It includes 38 free tools: HEIC to JPG, WebP to PNG/JPG/GIF, PNG to JPG, image compression and resizing, plus PDF tools to compress, merge, split and rotate. Available in seven languages; a privacy-friendly alternative to iLoveIMG, CloudConvert, Convertio and FreeConvert.
