💡 Tips to avoid font corruption
Always use standard Unicode fonts like Times New Roman, Arial, or Calibri. If using custom fonts, embed them in your document before saving.
Merge PDFs without breaking page order
Use Merge PDF when you need to combine invoices, contracts, scans, reports or application documents into one clean file. Select files in the order you want them to appear; if the sequence matters, rename files with numeric prefixes such as 01-contract.pdf and 02-appendix.pdf before selecting them.
- Check page order before sharing the merged file.
- Keep the total input size under the browser memory limit for faster processing.
- Use Split PDF afterwards if you need to remove accidental extra pages.
