Frequently Asked Questions

Are my files being uploaded to a server?

Image-to-image conversions (JPG, PNG, WebP, BMP) work entirely in your browser. TIFF, SVG, PDF, GIF, and DOCX conversions use secure server processing.

Which file formats are supported?

ByteCompress supports 9 formats: JPG, PNG, WebP, BMP, GIF, TIFF, SVG, PDF, and DOCX. Each format can be converted to the other 8 formats.

Is there a file size limit?

Files up to 1GB are supported. Performance depends on your device for client-side conversions and the server for server-side conversions.

Does the converter work on mobile?

Yes. ByteCompress works on all modern mobile browsers, including Safari on iOS and Chrome on Android.

Can I convert multiple files at once?

Yes. You can add up to 2 files for batch processing. Each file is converted independently.

What happens to transparent areas when converting to JPG?

JPG does not support transparency. Transparent pixels are replaced with a white background.
