Batch Tools
Same operation, many files, one download.
Batch work fails in a specific way: file seventeen is corrupt, and a naive implementation throws away the sixteen results that already succeeded. These tools process each file independently, report per-file status, and let one failure sit alongside the successes rather than cancelling them. Because the work is local, throughput is bounded by your own machine — but nothing is queued behind other users, and nothing is uploaded.

About batch tools
What happens if one file in the batch fails?
Only that file is marked failed, with the reason shown next to it. Every other file still completes and is included in the download, and you can retry the failed one individually.
How many files can I process at once?
A run accepts up to 250 files, with a 250 MB limit per file and a 600 MB combined input limit. PDF loading also enforces a 5,000-page limit per document. Your device may run out of memory below those limits. Per-file operations run sequentially, but all input bytes are loaded before processing and completed outputs remain in memory until the ZIP is built; merging has its own combined-document output. Use smaller batches for large scans or image-heavy conversions rather than assuming each completed file frees all its memory.
