Limits protect the browser session
PDF pages must be parsed and represented in memory before a new file can be created. Large files or many pages can use significant memory, especially on mobile devices. File and page limits make failures more predictable and keep the interface responsive.
When to use a smaller batch
- Split a large collection into smaller groups.
- Close other tabs when the browser is under memory pressure.
- Check the output after each operation before deleting the originals.
