Frequently Asked Questions

3 questions answered

Can I edit any PDF online for free?

You can edit any text-based PDF (created from Word, Google Docs, or any digital source). Scanned PDFs are images of paper and don't have editable text — use an OCR tool first to convert them.

Will my PDF look different after editing?

The replacement text uses Helvetica, a standard PDF font. For documents using Arial, Calibri, or similar sans-serif fonts, the result looks very close. Exact font matching is not possible without the original font file embedded in the PDF.

Is there a file size limit?

No. The editor processes your PDF entirely in your browser using pdfjs-dist and pdf-lib — there is no server upload, so there is no server-side size limit. Very large PDFs may take a few extra seconds to render.
