Free file tools that work in your browser
Prestofiles helps you get a file ready for the place it is going. Make a photo small enough for a job form, turn a PNG into a JPG that a website accepts, shrink a scanned certificate before you email it, or combine several pages into one document. Everything happens on your own phone or computer, so private pictures and papers are not sent to us.
Not sure where to start? Many visitors need an exact size, such as a passport photo under 50 KB or a document under 200 KB. Open one of the ready pages for those sizes and the target is already set. Prefer to learn first? Read the simple guides on our blog, or see the sites that list us on the listed on page.
