Paste a Screenshot and Resize Instantly (Ctrl+V)
Skip the Save-As step. Take a screenshot, hit Ctrl+V (or Cmd+V) inside ShareMint, and resize for any SNS in one motion.
If you publish tutorials, release notes, bug reports, or any content that starts with a screenshot, the "Save As → navigate to folder → open in resizer → locate file → upload" ritual adds up fast. ShareMint supports the Clipboard API on every major browser, so you can take a screenshot (Cmd+Shift+4 on macOS, Win+Shift+S on Windows), focus the ShareMint tab, hit Cmd+V / Ctrl+V, and have the image ready to resize in under 10 seconds — with no intermediate file ever written to disk.
Steps
Take your screenshot
Use Cmd+Shift+4 (Mac) or Win+Shift+S (Windows) to grab a region. The screenshot lands on your clipboard automatically — no need to save a file.
Open ShareMint in a tab
Either keep ShareMint open in a pinned tab, or open it now. The page is small and loads instantly.
Press Cmd+V / Ctrl+V
With ShareMint focused, hit paste. The screenshot appears in the preview window immediately. No file picker, no Save-As detour.
Pick a preset and resize
Choose your target SNS preset (X cards, Instagram portrait, blog hero, etc.) and click Resize & Export. Done in under 10 seconds.

Which screenshot tools work?
Anything that puts the image on your system clipboard: macOS's built-in Cmd+Shift+4, Windows Snipping Tool, ShareX, Greenshot, CleanShot X, and even browser screenshot extensions all work.
Does paste work on Safari and Firefox?
Yes. ShareMint uses the standard Clipboard API, which is supported in Chrome, Edge, Safari 13.4+, and Firefox.
Why is this faster than uploading?
You skip three steps: Save As, navigate to file, and select. Paste-to-resize is the fastest workflow when you are creating screenshot-based content like tutorials or release notes.
Can I add a watermark to the pasted image?
Yes. With the Pro plan you can stamp a logo, text, or QR code watermark on the result before exporting.
