Uploads take PDF files up to 4 MB. The message under the upload box tells you which limit you hit.
"Please choose a PDF file."
- The file is something else, such as a Word document or a photo.
- In Word, Google Docs or Pages, use Save as or Download and choose PDF. On a phone, most apps have Print, then Save as PDF or share as PDF.
- Upload the new PDF.
"This file is larger than 4 MB."
- Large PDFs are usually scans or contain big photos.
- Shrink it with a PDF compressor, or scan again at a lower resolution: 150 dpi in black and white is plenty for signing.
- If it's a long document, split off only the pages that need signatures.
- Upload the smaller file.
The page shows an error instead of the document
- Some PDFs are damaged or password-protected. Open the file on your computer; if it asks for a password, save an unprotected copy and upload that.
- Still stuck? Re-export the PDF from the program that made it, or print it to a new PDF, and upload again.
