Frequently Asked Questions

Can I combine different image formats into one single PDF?

Yes. DocScalar accepts heterogeneous image formats in a single batch, allowing you to organize, rotate, and compile them into a unified PDF with custom margins and uniform page dimensions without file errors.

Are my uploaded photos and documents kept confidential?

Yes. All uploaded images are transferred over TLS 1.3, processed in temporary memory buffers, and permanently purged immediately after PDF generation with zero disk storage or external network access.

What is the maximum file size for converting images to PDF?

DocScalar supports files up to 10 MB in instant guest mode with zero registration required, 15 MB for registered free accounts, and up to 1 GB for Pro tier users. All processing executes in isolated memory buffers with zero data retention.

Is image compression applied automatically?

DocScalar embeds images with original pixel dimensions by default, offering optional smart compression to produce lightweight files for email attachments while protecting fine photographic details.
