How to use this tool
- Drop in a PDF.
- Add text, a shape, a highlight, a line or arrow, or an image, then drag it into place.
- Adjust size, colour, or opacity from the toolbar that appears, then click "Save Edited PDF."
Frequently asked questions
- Is my PDF uploaded anywhere?
- No — everything, including rendering the page previews and every element you add, happens in your browser. The file never leaves your device.
- Can I edit existing text or content in the PDF?
- Not currently — every element you add sits on top of the page (great for filling in a blank, labeling something, or marking it up), rather than modifying content that's already part of the PDF.
- How do I underline or strike through existing text?
- Add a Line and position it under or through the text you want to mark — this tool doesn't detect existing text automatically, so you position the line yourself, the same way you would with a Highlight.
- Can I add elements to multiple pages?
- Yes — navigate between pages with the Prev/Next buttons and add elements to any of them before saving.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online tools |
|---|---|---|
| PDF ever leaves your device | No — edited in this tab | Yes, uploaded to process |
| Account required | Never | Often, past a certain usage level |
("Typical online tools" reflects publicly documented behavior of common free file-processing sites as of 2026 — always check a specific competitor's own privacy policy and pricing page, since these details change.)
