Social media video quality, explained
Resolution, bitrate, codecs and why the file you can download may differ from the creator's original upload.
PUBLIC MEDIA TOOLS, MADE SIMPLE
Save it. Inspect it.
Understand it.
ContentDown combines three available public-media downloaders with practical browser tools and original guides about media formats, quality, links and responsible use.
Live downloaders
Three platforms. Three purpose-built workflows.
No simulated results and no platform passwords.
More than a downloader
Work with the file after you find it.
Use small browser-side utilities to inspect a media file, calculate an aspect ratio or estimate video storage. These tools do not need a social-media URL.
From the field notes
Understand what platforms actually deliver.
Image resolution without the jargon
Pixels, megapixels, aspect ratio and what dimensions actually tell you about a social-media image.
Aspect ratios for social media: a practical guide
Understand 1:1, 4:5, 16:9 and 9:16, calculate ratios, and avoid accidental cropping.
JPEG, PNG, GIF, WebP and MP4: what changes?
A practical reference to the file types you encounter when saving public social media.
Public vs private social media: what a downloader can access
Why a public URL matters, what access controls mean, and why ContentDown never asks for your social account password.
How Instagram carousel downloads work
What happens when one Instagram post contains several photos or videos, and how ContentDown presents them.
How ContentDown works
A transparent public-media workflow.
Submit a public link
Each service validates links for its own platform. ContentDown does not ask for your social-platform password or private account session.
Review real media
The service identifies compatible media and presents the photos, video renditions, GIFs or collections it can actually retrieve.
Save responsibly
Your browser handles the final download. Public availability does not transfer copyright, so only save and reuse media you are entitled to use.
Maintained, not abandoned
Product documentation that changes with the product.
ContentDown's public capability notes, troubleshooting and guides are reviewed as its integrations change. Unsupported behaviour is documented rather than disguised behind generic error messages.
