Frequently asked questions
How many files can I process at once?
+
Up to 40 files per batch, each up to 50 MB and up to 500 MB in total. Files are processed one at a time so your browser stays responsive.
Can I mix PDFs and images?
+
Yes. In “Meet requirements” mode each file is checked and fixed against the same rules; in “Compress” mode PDFs use a quality level and images use your quality, format, and width settings.
What happens if one file fails?
+
The rest keep going. Failed files show the reason, and you can retry just those. Files that already meet the rules are marked unchanged and left as they are.
Are my files uploaded for batch processing?
+
No. Just like the single-file tools, everything runs in your browser. The ZIP is built on your device too.
