Frequently Asked Questions
Find solutions to common questions regarding annotating, highlighting, and inserting elements into PDF files.
Can I edit existing text directly like a word processor? expand_more
PDFs are compiled vector visual formats rather than flowable documents. Our editor lets you add new text layers, whiteout/redact existing sections, and insert annotations. To rewrite entire flowable text blocks, convert your file with our PDF to Word tool.
Will my annotations be visible in Adobe Acrobat and mobile PDF viewers? expand_more
Yes. All drawings, text callouts, and shapes are rendered into compliant PDF content streams and annotation dictionaries, ensuring universal visibility across all standard PDF readers.
Can I insert an image or signature graphic while editing? expand_more
Yes. You can import PNG, JPG, or WebP images and place them onto any page with full scaling and repositioning controls.
Are annotations permanently burned into the PDF? expand_more
When you export your document, annotations are embedded into the PDF structure, ensuring they cannot be accidentally detached when emailing to clients or colleagues.
Is there any subscription fee or page limit for editing? expand_more
Reshape is 100% free with unlimited usage. You can annotate as many files and pages as needed without recurring fees or account creation.
