Binary Response Viewer

Rostyman automatically detects binary responses and renders them natively instead of showing raw bytes.

Supported Types

Content Type	What You See
image/png, image/jpeg, image/gif, image/webp	Image with zoom controls
image/svg+xml	SVG preview + source code
video/mp4, video/webm	Native video player (play/pause/seek/volume)
audio/mpeg, audio/wav, audio/ogg	Audio player
application/pdf	Embedded PDF viewer
text/csv	Interactive table with row/column counts
Any other binary	File card (type, size) + Save to Disk button

How It Works

When the response Content-Type is a known binary or media type, the response body area switches from the text editor to the appropriate viewer automatically — no configuration needed.

Images

• Displayed at full width, max 100% of container
• Zoom In / Zoom Out / Reset Zoom buttons in the toolbar
• Images larger than the display area are scrollable
• SVG files are rendered as images; click View Source to see the raw XML

Video

• Uses the browser's native video element
• Supports play, pause, seek, volume, and fullscreen
• Shows video dimensions and duration in the toolbar

Audio

• Play, pause, seek bar, and volume control
• File size and duration shown in the header

PDF

• Rendered using the browser's built-in PDF viewer
• Download button to save the PDF locally

CSV

• Parsed into a scrollable interactive table
• Row and column count shown in the header
• First row is treated as the column header

Saving Binary Responses

Click Download in the response toolbar to save any binary response to disk. The filename is inferred from the Content-Disposition header or the request URL, with the correct file extension applied automatically.
