How to use this tool

  1. Drop an image file.
  2. Pick the output format and quality.
  3. Click Convert image and download.

Pick the right format

Use JPG for photos, PNG for graphics with transparency, and WebP when you want smaller web assets. After converting, try Compress Image for even smaller files.

Why use FreeTools?

Unlike many online utilities, FreeTools processes your files in the browser using modern Web APIs and WASM libraries. That means faster results on your machine, no waiting for uploads, and a clear privacy story: we never see your documents or photos. No account is required — open the page, drop a file, download the result.

FAQ

Which formats can I convert between?+

PNG, JPG, WebP, and AVIF (browser support permitting). Output quality is adjustable for lossy formats.

Why did AVIF fail?+

Some browsers cannot encode AVIF yet. Try WebP or JPG instead, or use a Chromium-based browser.

Do you upload my images?+

No. Conversion uses the Canvas API on your device.
