Updates, tutorials, and release notes for the iPhone utility Shortcut.
How to Resize a Photo to Exact Dimensions on iPhone
Grabio resizes an iPhone photo to an exact pixel width and height, for forms that demand a specific size like 600×600. Free, on-device, no app.
How to Download Twitch Clips on iPhone
Grabio reliably handles Twitch clips, the short highlight-reel format. Full VOD downloads are a separate, less consistent case worth knowing about upfront.
How to Reduce a PDF File Size for Email on iPhone
Shrink a PDF on iPhone so it fits under your email provider’s attachment limit, free, on-device, no app to install.
How to Download Pinterest Videos on iPhone
Pinterest’s own save button often grabs a thumbnail instead of the actual video. Grabio routes Pin links to cobalt.tools so you get the real video file.
How to Download Reddit Videos on iPhone
Reddit’s native video save keeps audio and video as two separate files. Grabio routes Reddit links straight to cobalt.tools, which merges them into one clean file.
How to Download a Video from X (Twitter) on iPhone
X pulled its native download button years ago. Grabio reads a tweet link, sends it to cobalt.tools with the link already loaded, and gets you the video in one tap.
How to Generate a QR Code on iPhone (Free, No App)
Grabio uses Apple’s native Shortcuts QR code action to turn any link or text into a QR code right on your iPhone. No account, no logo watermark, no upload.
How to Convert Audio to MP3 on iPhone
iOS has no built-in action to encode MP3, so Grabio hands the job to VERT, a free clean converter site, while keeping its other audio tools fully on-device.
How to Download TikTok, Instagram & Other Videos on iPhone
Grabio recognizes links from TikTok, Instagram, and 13 other platforms, then opens cobalt.tools with your link already loaded, no manual pasting, no watermark, no ads.
How to Download YouTube Videos on iPhone (No App)
Share a YouTube link with Grabio and it opens a clean, ad-free downloader with your link ready to paste. Two taps, no app, no watermark tool, and Grabio’s own server never touches the video file.

Convert any audio file to M4A on iPhone in a few taps with Grabio’s free, on-device Audio → M4A tool — no app install, no upload.
