Is there a Convertio alternative that does not upload my files?

Yes, for images. This converter runs entirely inside your browser, so the file never leaves your device. You can confirm it by loading the page, disconnecting from the internet, and converting an image anyway.

Can it convert audio, video or documents like Convertio does?

No. We convert images between JPEG, PNG and WebP. Convertio supports hundreds of formats across audio, video, documents, archives and more, so for anything that is not an image, use them.

Is there a daily limit?

No. There is no daily conversion cap and no account to sign up for. The work happens on your own device, so the only limit is how fast your device can process a file.

Does it cost anything?

No. There is no paid tier, no account and no daily quota.

JPEG, PNG and WebP, in any direction between them. To shrink an image without changing its format, use the image compressor .
