Why use a browser-based file converter?
Traditional online converters upload your files to a server, process them remotely, and send back the result. That means waiting in queues, hitting arbitrary size limits, and — most importantly — trusting a stranger's server with your photos and documents. FileLark works differently: every conversion runs locally in your browser using the Canvas API and WebAssembly. Nothing is uploaded, ever.
What can you convert?
Images: JPG, PNG, WebP, AVIF, GIF, BMP and iPhone HEIC photos, with batch conversion, resizing and compression to a target file size. PDFs: convert pages to images, combine images into a PDF, merge, split, compress, rotate and delete pages. And for AI artists, the image-to-prompt generator turns any picture into ready-to-use Midjourney and Stable Diffusion prompts.
Free forever — here's how
Because conversions happen on your device, running this site costs almost nothing — there are no processing servers to pay for. The site is supported by unobtrusive ads, which means every tool stays free, unlimited, and available without an account.
