Supported File Types & Previews

Onlinedrive can store any file type. Many file types also support in-browser preview.

Fully Previewable

These file types open in the built-in previewer when you click them:

Images

• JPEG (.jpg, .jpeg)
• PNG (.png)
• GIF (.gif) — including animated GIFs
• WebP (.webp)
• SVG (.svg)
• BMP (.bmp)
• HEIC/HEIF (.heic, .heif) — iPhone photos, auto-converted for display

Video

• MP4 (.mp4)
• WebM (.webm)
• MOV (.mov)

Audio

• WAV (.wav)
• OGG (.ogg)
• AAC (.aac)

Documents

• PDF (.pdf) — full embedded viewer
• Plain text (.txt)
• CSV (.csv)
• JSON (.json)
• Other text-based files

Storage Only (No Preview)

These files can be uploaded, stored, downloaded, and shared, but won't preview in the browser:

• ZIP, RAR, 7Z (archives)
• DOCX, XLSX, PPTX (Office documents)
• PSD, AI (design files)
• EXE, DMG (executables)
• Any other file type

Thumbnails

Images and videos automatically generate thumbnails that appear in the file browser grid view, making it easy to identify files visually.

HEIC Support

iPhone photos use the HEIC format, which most browsers can't display natively. Onlinedrive automatically converts HEIC files to JPEG for preview, so you can view your iPhone photos without any extra steps.
