    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.

  • 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 PNG 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.

The best of both worlds

PNG supports transparency but produces large files; JPG is small but has no transparency. WebP offers both: transparent graphics and photos at a fraction of the PNG file size – often 50–80% smaller.

Ideal for websites

Product photos with transparent backgrounds, logos, illustrations and screenshots load much faster as WebP. That improves page speed and Core Web Vitals.

Lossy or near-lossless?

At quality 90–100 WebP keeps graphics crisp; at 75–85 photos become very small with little visible difference. Try a few settings – the size after conversion is shown next to each file.

Frequently asked questions

Does WebP keep the transparent background of my PNG?

Yes. WebP supports transparency, so transparent areas stay transparent.

How much smaller will my PNG be as WebP?

Often 50–80% for photos and detailed images; simple graphics shrink less.
