Frequently asked questions

Can the new logo be the same size as the old one?

Yes. The logo takes the exact size and position of the rectangle you draw around the old logo. Choose Keep proportions if you do not want it stretched.

Which image formats can I use?

PNG, JPG, WebP and SVG images work. A transparent PNG gives the cleanest result.

Is the old logo gone for good?

The old logo is erased from view and the paper behind it rebuilt, but in the default export the original image can still exist underneath. Export with Flatten pages if it must be removed completely.

Is DocuFix Studio really free?

Yes. It is free to use, with no sign-up, no watermark added by us and no page limit.

Is my PDF uploaded to a server?

No. Your PDF is opened and edited inside your own browser and is not uploaded anywhere, so confidential documents stay on your device. Only the editing libraries and fonts are downloaded when you first open the page.

Does it work on a phone or tablet?

Yes. The editor is designed for touch screens as well as desktop: pinch to zoom, drag to draw, and install it as an app from your browser menu. It also supports a light and a dark theme.

Can it remove every kind of watermark?

Not always. It works best on watermarks drawn in a consistent colour, such as grey or coloured diagonal text and stamps on a plain background. Watermarks that are part of a photo, or that share the colour of your text, may leave traces and need the Area Patch or Brush tool. Only remove watermarks from documents you own or have permission to edit.
