Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
ඔව්: free use has a size limit per document, and the page tells you when a file is over it; Ghostscript and qpdf do the work. පරිලෝකනය කරන ලද PDF ෆයිල් එයට වඩා වැඩි වන සාමාන්ය දෙයක් වන අතර, ලේඛනය සම්පීඩනය කිරීම සාමාන්යයෙන් එය නැවත ගෙන ඒමට ප්රමාණවත් වේ.
No account is needed. Uploads and results are kept for about 24 hours, which leaves time to download the result, and are then deleted automatically; nobody reads, lists or indexes them. Several files in one job need a paid plan.
