FAQ

Image converter questions, answered

Are my images uploaded to a server?

No. Every conversion, compression and resize happens locally in your browser using the Canvas API. Your files never leave your device, which also makes the tool fast and private.

Which image formats can I convert?

You can convert between JPG, PNG, WebP, AVIF and BMP, import SVG files, and extract still frames from GIFs. WebP and AVIF availability depends on your browser, and all modern browsers support them.

How do I compress an image to a target file size?

Upload your image, choose an output format like WebP or JPG, then lower the quality slider until the live preview shows the file size you need. You can also resize dimensions to reduce size further.

Can I process multiple images at once?

Yes. Drop a whole batch into the queue, apply one set of output settings to all of them, then download files individually or export everything together.

Is the tool free?

Yes, the image converter, compressor and resizer is completely free with no sign-up, no watermarks and no file limits imposed by a server.
