Frequently Asked Questions

Can I edit the existing text in a PDF?

This tool adds new content on top of the PDF. To modify existing text, you would need to use the eraser tool to cover the original text and then add new text in its place.

What image formats can I insert?

You can insert PNG, JPEG, and WebP images. They will be embedded directly into the PDF when you download the edited file.

Is there a file size limit?

There is no hard limit. Processing happens in your browser, so it depends on your device's memory. Most devices handle files up to 100MB comfortably.

Are my files uploaded to a server?

No. Everything runs locally in your browser. Your documents never leave your device.

Does it work on mobile?

Yes. The editor is fully responsive with touch support for drawing and a mobile-optimized toolbar at the bottom of the screen.

Can I undo my changes?

Yes. Use Ctrl+Z to undo and Ctrl+Y to redo. The full edit history is preserved until you close the editor or download the file.

How do I add shapes with no fill?

Select the Shape tool, then click the "No Fill" button in the properties bar. This will draw only the outline of the shape with the stroke color you have selected.

Does the editor modify the original PDF content?

No. All edits are overlaid on top of the existing PDF content. The original text, images, and formatting remain untouched underneath your additions.
