Video, Audio, PDF, and File Downloads

Q: Why can't I upload `.mov` videos from my iPhone?

.mov is an Apple-specific container (usually HEVC encoded) that often fails to play in browsers on Windows or Android. To ensure all visitors can view your content, please export your video as a cross-platform compatible .mp4 or .webm file before uploading.

Q: Why can't I find PDF in the blog file attachment block?

PDFs have a dedicated "PDF" block in the blog editor, which supports full-screen reading and thumbnail previews rather than just a download card. Type / and select "PDF" to upload or pick from your library.

Q: What does "Archive contains executable files" mean when uploading a `.zip`?

To prevent malware distribution, the system scans .zip contents. If it finds executable programs or installers like .exe, .dmg, .pkg, .bat, .sh, or .apk, it will block the upload. Please remove these files and re-compress your assets before trying again.

Overview

Beyond images, you can upload videos, audio, PDF documents, and various downloadable files (Word, Excel, PowerPoint, EPUB, ZIP) directly to Kanorio to include in your website pages, blog posts, or digital products.

All self-hosted media and PDFs use Kanorio’s built-in player and reader: the interface is clean and consistent, free of third-party ads, and won’t distract visitors with recommended videos from other channels at the end of playback.

Direct Upload vs. Embedding (YouTube/Spotify): Which to Choose?

When adding video or audio to your site, you can either "upload the file directly to Kanorio" or "embed an external link via an integration module." Each serves a different purpose:

Comparison	Upload directly to Kanorio	Embed YouTube/Spotify/Podcast
Best for	Brand hero videos, product demos, lecture notes, long-form sessions where you want no distractions, or digital product courses that require payment to unlock.	Channels already active on YouTube, Spotify, or Apple Podcast that you want to grow in views and subscribers.
Viewing experience	Uses the built-in website player—no ads, no external channel branding, and no recommended videos at the end.	Uses the external platform's player, which may show recommended videos, end-screen links, or ads.
Download control	You decide whether to allow visitors or buyers to download the original files.	Files cannot be downloaded from your website; visitors must return to the original platform.
Website storage	Counts toward your shared (but no bandwidth fees and no limits on total views).	Files are hosted on external platforms and do not occupy your website storage.

If you want to embed public links from YouTube, TikTok, Instagram Reels, Spotify, or Apple Podcast, please use the corresponding integration module. See setup steps in .

Built-in Video and Audio Player Features

Whether in a "Multimedia Content" module on a page, within a blog post, or on a customer's "Purchased Content" page, your uploaded media uses the same professional player. Both desktop and mobile visitors can enjoy these features:

Resume Playback and Volume Memory: If a visitor or student closes the page, refreshes, or returns the next day, the player automatically resumes from the exact second they left off. This is ideal for long lectures, podcasts, and online courses.
0.5x to 2x Playback Speed: Click the gear icon in the player to toggle between 0.5x, 0.75x, 1x, 1.25x, 1.5x, 1.75x, or 2x speed.
±10s Seek and Mobile Double-Tap: The control bar includes 10-second rewind and fast-forward buttons. On mobile or tablet, double-tap the left or right side of the video to skip 10 seconds, or double-tap the center to toggle full screen.
Progress Bar Preview: Hover over the progress bar to see a timestamp preview, making it easy to jump to specific sections.
Picture-in-Picture (PiP) and Casting: Enable "Picture-in-Picture" in the gear menu to keep the video floating in the corner while browsing other content. If the visitor's device supports AirPlay or Chromecast, a cast button will automatically appear for big-screen viewing.
Responsive Interface: When displaying multiple videos in a grid, the player automatically hides secondary buttons for a cleaner look. The full control bar appears when the visitor expands the view or enters full screen.
Keyboard Shortcuts (Desktop): When focused on the player, use Space or K (Play/Pause), J/L or Left/Right Arrows (Seek), M (Mute), and F (Full Screen).

Auto-Generated Thumbnails and Album Art

To avoid a black screen before playback, Kanorio automatically generates a cover image after upload:

Video: Automatically captures a clear frame near the 1-second mark as a 16:9 cover.
Audio: Automatically reads embedded cover art (e.g., MP3 ID3 tags or M4A art). If no art is embedded, an audio icon is displayed.
Manual Override: The "Multimedia Content" module displays the auto-generated cover by default. You can upload a custom cover at any time, or revert by selecting "⋯ → Revert to auto-cover."

Built-in PDF Online Reader

When you upload a .pdf file in a "Multimedia Content" module, blog post, or digital product, visitors don't need to download it to view it; they can interact with it directly on the page:

Auto-Generated Thumbnails and Page Count: Upon upload, the system captures the first page as a preview cover and displays the total page count (e.g., 12 pages) in the corner.
Full-Screen Reader: Clicking "Read" or the cover expands the full-screen reader, supporting zoom and continuous scrolling. On desktop, a page thumbnail sidebar can be expanded for quick navigation.
On-Demand Loading and Mobile Optimization: Even for high-resolution catalogs or handouts, the reader only downloads the page the visitor is currently viewing and clears memory for unused pages, ensuring smooth scrolling on mobile without crashes.

File Download Cards (Word, Excel, PowerPoint, EPUB, ZIP)

For event forms, spreadsheets, presentations, EPUBs, or design assets (.zip), the site automatically generates a clear "File Download Card":

Automatic Type and Size Labeling: Cards display a color-coded format label (e.g., DOCX, XLSX, PPTX, EPUB, ZIP), filename, and file size. Visitors can click "Download" to save the file directly to their device.
Security Scanning and Format Verification: To protect your visitors and customers, the system verifies the actual file header during upload (preventing disguised file extensions) and automatically scans the internal directory of .zip files.
Executable File Restriction: If a .zip file contains executable programs or system installers (e.g., Windows .exe, .msi, .bat, .cmd, .ps1; macOS/Linux .dmg, .pkg, .app, .sh; mobile .apk, .ipa), the system will reject the upload. Standard web-related code files like .js or .py are permitted.

Media, PDF, and File Format Limits

For standard image limits (40 MB), see . The following table outlines file size limits and supported extensions (subject to your site's remaining ):

Tips

Keep your browser tab open until the progress bar completes when uploading large videos. Uploading directly in the "Media Library" allows you to switch tabs without interrupting the queue.
For tutorials or product demos, export as 1080p .mp4 (H.264) for the best compatibility and file size balance across all devices.
