guides & how-tos
Practical, honest guides for saving videos, photos, and audio from every platform FastSaver supports — and how to do it responsibly.
TikTok Downloader API: Clean Video + Sound in One Call
One GET returns the clean MP4, the sound as MP3 and the cover image. The exact response shape, photo-mode posts, short links, and the errors worth handling.
Six Things Developers Build with a Media Download API
A media download API is a lego brick. Six things people actually build with it, plus honest notes on architecture and what not to build.
Getting Started with the FastSaver API
Auth, a first request in curl, JavaScript and Python, how to read the medias array, and honest advice on errors and rate limits.
Instagram Downloader API: Reels, Photos and Carousels
Reels come back as one MP4, carousels as a medias array with one entry per slide. The exact shapes, the errors, and why Instagram breaks more than the rest.
How to Download Videos Without Leaving Telegram
Message a link to @fastsaver_bot and the file comes back in the chat. The fastest way to save videos if you live in Telegram anyway.
How to Download TikTok Videos Without a Watermark
TikTok stamps a watermark on everything you save in the app, but pasting the link into a browser downloader gets you a clean HD copy in under a minute.
YouTube Download API: Pick a Format, Get a Stream
YouTube has formats, so it is two calls: list them, then resolve one to a tunnel URL that redirects to the stream. Both requests, both responses, and the failure modes.
Everything FastSaver Can Do
You probably use 20% of it. The full map — six platforms, three ways to use them, and the things FastSaver refuses to do on purpose.
How to Download YouTube Videos to Your Phone or Computer
Paste a YouTube link into fastsaver.io, pick a quality up to 4K, and save the video as a real MP4 on any device.
How to Download Instagram Reels in Original Quality
Copy the Reel link, paste it into FastSaver, and the original MP4 with sound is yours in about thirty seconds, no login needed.
How to Convert YouTube to MP3 in Your Browser
Paste a YouTube link into FastSaver, flip the audio-only toggle, and the download comes back as an MP3 instead of a video.
How to Download a TikTok Sound as an MP3
Paste a public TikTok link into FastSaver, turn on the audio-only toggle, and the sound saves to your device as a clean MP3.
How to Download YouTube Shorts
Shorts URLs paste into FastSaver like any other YouTube link: copy the link, pick a quality or MP3, and the file saves in seconds.
How to Download Videos and GIFs from X (Twitter)
Copy the post link, paste it into FastSaver, and any public X video or GIF saves as an MP4 in about thirty seconds.
How to Download Facebook Videos and Reels in HD (or SD)
Facebook never gives you a real download button, but saving a public video or Reel takes about thirty seconds: copy the link, paste it into FastSaver, pick HD or SD.
How to Download Instagram Photos in Full Resolution
Instagram won’t let you save photos directly, but pasting the post link into FastSaver gets you the full-resolution file on any device, free.
How to Save Videos on iPhone and Android
Downloads land in the Files app on iPhone and the Downloads folder on Android; here’s how to get them into your camera roll.
How to Download Pinterest Videos and Full-Size Images
Copy the pin link, paste it into FastSaver, and get the original video or full-resolution image instead of a blurry grid save.
Is It Legal to Download Social Media Videos?
Saving a public video for private offline viewing rarely causes real trouble, but reposting or monetizing someone else’s work does, and platform terms are a separate rulebook.
