Why conversion in the browser is better

Most online converters work by uploading your file to a server, converting it there, and handing back a download link. That means a copy of your document sits on someone else's machine, often for hours, and you have to trust a privacy policy you did not read.

Modern browsers can do the same work themselves. Every tool on this site uses the browser's own image and document engines, so your file is read from disk, converted in memory, and written straight back to your downloads folder. Nothing is transmitted at any point — you can switch off your internet connection after the page loads and the tools still work.

It is also faster. There is no upload wait, no queue, and no download step, which makes a noticeable difference when converting a batch of large photos.

Frequently asked questions

Is this really free?

Yes. There is no account, no trial, and no paid tier. The site is funded by the ads shown around the tools.

Is there a file size limit?

No fixed limit. Since your own device does the work, the practical ceiling is your available memory — far higher than the caps upload-based converters impose.

Does it work on a phone?

Yes. Every tool works on mobile browsers, including selecting photos straight from your camera roll.

Do you keep or see my files?

We cannot. Files are never sent to us — conversion happens entirely inside your browser, so there is nothing on our side to store.
