Frequently asked questions

Which image formats can I convert?

Common browser conversions include JPG, PNG, and WebP. Additional input formats such as TIFF and HEIC depend on server-side conversion support.

Does changing an image to JPG reduce quality?

JPG uses lossy compression. You can adjust the quality setting for supported conversions; PNG output is lossless.

Is this tool free to use?

Yes. The converter is free to use and does not require an account.

Can I convert several files at once?

The tool processes one uploaded file per conversion. Run each file separately.

How large can my upload be?

The server accepts uploads up to 50 MB. Common browser-based image conversions are limited to 25 MB and 40 megapixels.

How are uploaded files handled?

Server conversions use temporary files that are removed after the response finishes. Browser image conversions run locally; hosting logs and optional OCR providers are controlled by the site operator. See the privacy page for details.
