Convert files in your browser — nothing ever uploaded

3 followers

Every online converter uploads your file, processes it on a server and sends it back — which costs the operator money per file, so they cap the size, add queues or make you sign up. powarca does the work inside your browser tab instead: images, audio and PDFs, 15 languages, no account, no queue, no file-size limit. Free, funded by ads that appear after the conversion rather than in front of it.

Two things I would push back on if someone else had built this. First, "nothing is uploaded" is not marketing: the vendors that do the work are all client-side — libheif compiled to WebAssembly for HEIC, UTIF for TIFF, gifenc for GIF, pdf-lib for PDF output, lamejs for MP3. They are fetched on demand, so a PNG-to-JPG conversion pulls 37 KB of JS, not 3 MB. Second, the limits that remain are real: AVIF output depends on the browser's own encoder, and very large images are bounded by your device's memory. I would rather say that up front than pretend there is no ceiling. Happy to answer anything about how the pieces fit together.
