About File Viewer
Got a file you can't open? Drop it here and Kitbly shows it in your browser – no Office, no Hancom, no special app. PDF, Word (DOCX, DOC, ODT, RTF), Excel (XLSX, XLS, CSV, ODS), PowerPoint (PPTX, PPT, ODP), Korean HWP and HWPX, images including iPhone HEIC, TIFF, SVG, WEBP and AVIF, text and code, e-books (EPUB, MOBI, AZW3), audio and video, and archives (ZIP, RAR, 7z, TAR) – you can even open the files inside an archive. The file type is detected automatically. Everything is shown on your device and nothing is uploaded; only a few formats browsers can't read (old .doc and .ppt, Pages, Numbers, Keynote, DjVu, XPS, MOBI) are converted once on our server. From the viewer you can download, print, convert the file to another format or open it in our free editors.
