Frequently Asked Questions
Can I edit existing text in a PDF?
HonestPDF lets you add new text, highlights, drawings, and shapes on top of any PDF. Editing the original embedded text is not supported in browser-based tools. For that, first use HonestPDF's PDF to Word converter.
Will my edits show up in Adobe Acrobat and other readers?
Yes. All annotations are rendered into the final PDF as standard page content, so they appear in Adobe Acrobat, macOS Preview, Chrome PDF viewer, and every other PDF reader without special software.
Is there a watermark on the output PDF?
No. HonestPDF never adds watermarks to your edited PDFs. Most online PDF editors stamp their logo on the output unless you pay. HonestPDF is free without that catch.
Can I edit a scanned (image-based) PDF?
Yes. You can add annotations on top of a scanned PDF. To make the underlying scanned text searchable, first run it through HonestPDF's OCR Scanner, then come back to edit.
Does Edit PDF work on my phone?
Yes. The editor supports touch gestures on iOS Safari and Android Chrome, including pinch-to-zoom, drag-to-move annotations, and tap-to-select. Larger PDFs may run slower on older mobile devices.
What is the difference between Edit PDF and Fill PDF?
Fill PDF is for completing forms - typing into text fields, checking boxes, adding signatures and dates. Edit PDF is for marking up content - highlighting, drawing, adding comments, inserting images. Use Fill PDF for form filling, Edit PDF for visual annotation.
What is the difference between Edit PDF and Sign?
Sign is purpose-built for adding electronic signatures with date and initials. Edit PDF includes signature insertion as one of many annotation tools. Use Sign for signature-only workflows, Edit PDF when you need to sign and annotate together.
Are there file size or page count limits?
No hard limits. The practical limit is your device's memory. Most modern devices handle PDFs up to 100 pages and 50 MB without issues. For larger files, consider compressing or splitting first.
