    Always synced: the tools on your board, their order and size.

  • The windows open on your start page, including what you typed in them.

  • Every note in the notepad – on the notepad page, on your board and in windows.

  • Every list of website shortcuts – on the shortcuts page, on your board and in windows.

  • Every grid in the cover grid maker – on its page, on your board and in windows.

  • Keeps your pipeline and saved recipes on all your devices. Your files are never synced – only the steps and settings.

Turning something off removes it from your account straight away. Your devices keep their own copy.

Notifications

Tools that can tell you about something new while a Synsi tab is open, even when you are in another tab or app. Choose them for this browser.

This browser cannot show notifications from websites.
Notifications are blocked for this site. Allow them in your browser’s site settings (the icon left of the address), then switch them on here.

  • Says “New message” while a Synsi tab is open – never who wrote it or what.

Your choice is stored in this browser only. Notifications never show personal content such as a message or a number. They work while a Synsi tab is open; closed tabs get none.

How to use the JPG to WebP

  1. 1 Choose the output format (JPG, PNG or WebP) and, for JPG and WebP, the quality.
  2. 2 Optionally make the images smaller: after you add an image, its width and height are filled in – lower one and the other follows to keep the aspect ratio.
  3. 3 Drop your images on the page and download them one by one or all at once as a ZIP file.

Faster websites with WebP

WebP images are typically 25–35% smaller than JPG at comparable quality. Smaller images load faster, which improves Core Web Vitals such as Largest Contentful Paint – a ranking signal for Google – and saves mobile data for your visitors.

Browser support

All modern browsers – Chrome, Edge, Firefox and Safari (since version 14) – display WebP, so you can use it on almost any website today.

Tips

  • Combine conversion with resizing: set a maximum width such as 1600 or 1920 px for full-width photos.
  • A quality of 75–80 is usually indistinguishable from the original on screen.
  • Keep your original JPGs as a backup for printing.
