Frequently Asked Questions
Can I edit the amounts on a PDF invoice?
Yes, EasyPDF allows you to directly edit text in your PDF invoice, including amounts, dates, and client information. The original formatting is preserved.
Is it safe to edit invoice PDFs online?
Absolutely. EasyPDF processes your files client-side in your browser. Your documents are never stored on our servers.
Can I add my company logo to a PDF invoice?
Yes, you can add images including your company logo to any PDF invoice using the EasyPDF editor.
What happens to embedded fonts when I ocr a invoice?
EasyPDF reuses the same embedded font for new text whenever the font is included in the PDF. If the font is missing (rare for invoices), the editor substitutes the closest match from Google Fonts and warns you visually.
How long should I keep the original invoice on file?
Tax record retention 3-7 years; OCR enables IRS audit response by making scanned invoices searchable. The exact retention period depends on your country and industry, but always store the original alongside any corrected version to maintain a clean audit trail.
Can I convert an edited invoice back to Word or Excel?
Yes, after saving your edits, use the PDF-to-Word or PDF-to-Excel converter. Tables convert with reasonable fidelity for documents with a clear column structure. Expect to clean up formatting for complex invoices with multiple sub-totals or nested tables.
Will the recipient know I edited the invoice?
A standard PDF reader does not show an edit history by default. However, the file's metadata can include modification timestamps. For full transparency on material changes, attach a short note explaining the correction when you send the updated invoice.
Can I add a watermark before sharing the invoice?
Yes, EasyPDF has a free watermark tool. A "DRAFT" or "COPY" overlay is useful when sharing a corrected invoice for review before the final version goes out.
How do I redact sensitive fields on a invoice before sharing?
Use the redaction tool (not just black text on top). Select the area, choose "Black out and remove text", then save with the "flatten" option. This removes the underlying data permanently so advanced PDF readers cannot recover it.
What does the upload threshold benchmark mean for my invoice?
According to industry sources, 25 MB is the upload threshold. Keep this in mind when preparing or sharing your invoice, since exceeding this threshold typically triggers a rejection or a manual review at Tesseract, ABBYY FineReader, and Adobe Acrobat Pro for OCR; QuickBooks and Xero for invoice ingestion with built-in OCR..
Is it legal to ocr a invoice PDF?
Editing a PDF for legitimate corrections (typos, address updates, formatting) is generally allowed. Altering substantive figures, dates, or signatures to misrepresent the document to a third party is fraud and is prosecuted under IRS Publication 583 requires invoices to remain readable; OCR converts scanned invoices to searchable, editable text for tax purposes.. Always keep the original as evidence.
Will ocring my invoice affect its legal validity?
A PDF that has not been digitally signed remains valid after editing, since validity rests on substance, not file format. Once a invoice has been digitally signed, any edit invalidates the signature. For signed documents, issue a corrected version with a fresh signature instead.
How do I ocr a invoice PDF scanned from paper?
Run OCR first so the text becomes selectable. EasyPDF detects scanned PDFs and offers OCR in a single click. Proofread the OCR result on small fonts, since digit recognition errors are common on dense invoices.
