Yes! Our editor extracts all text content from your PDF using industry-standard PDF.js technology. You'll see blue outlines appear over each text block when you hover — click any of them to type your changes. We then white-out the original and write your new text at the exact same position.

PDFs often embed proprietary or custom fonts that we can't reproduce exactly. When you edit text, we replace it with your chosen font (Roboto, Open Sans, etc.) at the same size and position. For most documents this looks great, but there may be minor styling differences if the original used a rare or custom typeface.

These are Microsoft proprietary fonts that can't be embedded in PDFs from a browser. Use Roboto as an Arial alternative, Lato for Calibri, and Inter for Segoe UI — they're visually very similar and freely embeddable.

Absolutely not. Everything happens inside your browser tab. Your PDF bytes are loaded into browser memory, edited using JavaScript libraries (pdf-lib and PDF.js), and the modified file is generated locally. Nothing ever touches our servers.

Scanned PDFs are essentially images. There's no text layer to extract or edit. You can still draw on them, add text overlays, add highlights, and insert images — but clicking on the "text" in a scanned page won't work since it's just pixels, not actual characters.

PDF doesn't have a reflowing layout engine like HTML — the page is fixed. If your replacement text is longer, it may extend beyond the original boundary. We recommend keeping edits roughly the same length, or using a slightly smaller font size if needed.
