Quick Copy lets you save any type of clipboard content, including text, links, and images, then instantly copy or share them with other apps. Depending on the item type, you can redirect content directly to specific apps such as WhatsApp, Telegram, SMS, e-mail, or phone dialers. The app also supports images, including SVG files, and allows you to paste supported images directly from your clipboard. You can extract text and images from Instagram posts, Tweets, or almost any website, then copy, edit, or share them easily. Quick Copy also makes it simple to manage your content by pinning important items to the notification bar for quick access outside the app. For security and backup, you can automatically or manually back up your items to Google Drive with optional end-to-end encryption protected by your own password. The app itself can also be locked using a PIN or fingerprint for additional privacy. If you prefer local backups, you can export and import your items as JSON files, or export them in JSON, TXT, XLSX, and DOCX formats.
