Are my photos uploaded to a remote server during conversion?

No. All image processing runs locally in your browser using client-side JavaScript and Canvas APIs. Your photos never leave your computer or phone.

Can I convert multiple images at once?

Yes. You can select and convert dozens of files in a single batch. Once finished, you can download all converted files together as a convenient ZIP archive.

Does this tool support iPhone HEIC and scanner TIFF formats?

Yes. The converter fully supports Apple HEIC/HEIF files and scanner TIFF/TIF files, turning them into web-friendly JPG, PNG, or WEBP formats.

Is there a daily file size limit or watermarking?

There are no file size limits, daily conversion caps, or watermarks. The tool is free and relies on your local device memory to process files of any size.
