Common pitfalls and solutions

Pitfall 1: Deleting wrong pages

Once deleted, pages cannot be recovered (unless you have a backup).

Solution: Always keep a backup of the original PDF before deleting.

Pitfall 2: Index偏移问题 (Index Shift)

When deleting multiple pages, if you delete from front to back, the indices shift.

Solution: Delete from back to front, or use a tool that handles this automatically.

// Correct: Delete from back to front
const pagesToDelete = [2, 5, 8].sort((a, b) => b - a)
for (const index of pagesToDelete) {
  pdf.removePage(index)
}

Pitfall 3: Deleting "blank" pages that aren't blank

Some pages look blank but contain hidden content (watermarks, annotations).

Solution: Zoom in and check each page before deleting.

Pitfall 4: File size doesn't decrease

Deleting pages may not reduce file size if hidden data remains.

Solution: Run compression after deletion.

Pitfall 5: Bookmarks become invalid

Deleted pages may cause bookmark page references to break.

Solution: Check and update bookmarks after deletion.

Tips for best results

Always backup first. Keep the original PDF before any deletion.

Preview before deleting. Check each page's content before marking for deletion.

Delete from back to front. If deleting multiple pages, start from the last page.

Verify the result. Open the deleted PDF to confirm pages were removed correctly.

Use private tools for sensitive docs. Browser-based tools keep your documents secure.
