All processing happens in your browser. No files are uploaded to any server. How to verify

Need to convert a PNG to JPG to reduce file size? Or a WebP to PNG for compatibility with older software? Most converters upload your image to do the format change. For private images, that's an unnecessary risk.

Pulsyr's image converter handles format conversion entirely in your browser using Canvas. Your image stays on your device the whole time.

Why this is actually private

  • Conversion uses the Canvas API in your browser — no server upload.
  • All major formats supported: JPG, PNG, WebP.
  • Disconnect WiFi after page loads — still works.
  • Verifiable in DevTools → Network tab: zero requests.
Verify it yourself. Open your browser's DevTools (Cmd+Option+I on Mac, F12 on Windows), go to the Network tab, then use the tool above. You'll see zero network requests during the conversion. Most online tools can't make this claim because they upload your file to do the work.

How to use

  1. 1Drop your image file into the upload area.
  2. 2Pick the output format (JPG, PNG, or WebP).
  3. 3Click Convert.
  4. 4Download the converted file.

Frequently asked questions

Which formats are supported?

JPG, JPEG, PNG, and WebP. You can convert between any of these formats.

Will my image be uploaded?

No. Format conversion happens via the Canvas API in your browser. Your image never leaves your device.

Does converting between formats lose quality?

JPG is lossy, so converting to JPG reduces quality slightly. PNG and WebP can be lossless. The converter uses the highest quality settings by default.
