Fix sideways pages and delete the rest
Scanners and phone cameras love producing sideways or upside-down pages. This tool shows a thumbnail of every page in your PDF; rotate any page in 90° steps and mark unwanted pages for deletion, then download the corrected document.
Rotation is applied losslessly as PDF metadata — page content is never re-compressed, so quality is untouched and text stays selectable.
How it works
Drop a PDF above and wait a moment while page previews render. Click the rotate button on any page (each click turns it 90° clockwise) and the trash button to toggle deletion. Press Apply and the new PDF downloads instantly.
Unlike most online converters, FileLark never uploads your files to a server. The conversion runs entirely inside your browser using modern web technology, which means it works offline once the page has loaded, there are no file size queues or daily upload limits, and your images can never be stored, scanned, or leaked — they simply never leave your device.
