- WASM codecs — @jsquash (MozJPEG, libwebp, OxiPNG, imagequant, libavif), gifsicle-wasm-browser, SVGO

- PDF via pdf-lib and pdf.js
- No backend processing for file conversion — privacy by design
Most online file converters upload your files to their servers — your invoices, photos, contracts. Convertilo runs the same codecs (MozJPEG, libavif, OxiPNG, etc.) as WASM modules inside your browser. The files never leave your device.
