Adobe Acrobat costs hundreds of dollars per year. But you don't need it to edit a PDF. Here's how to add text, erase content, add images, insert page numbers, and add watermarks — all for free in your browser.
Using PDF Studio at pdfeditor.onl/pdf-studio, you can add new text anywhere, erase existing content, overlay images, draw freehand annotations, add a watermark, insert page numbers, and run OCR on scanned text. All without any software installation.
Open PDF Studio and upload your PDF. Select the Text tool from the toolbar. Click anywhere on the page to place a text box and start typing. You can change the font, size, color, and alignment.
Tip: To match the existing PDF text style, zoom in first to inspect the font size, then set yours to match.
Select the Eraser tool and draw over any content you want to remove. The eraser paints a white rectangle over the selected area, effectively redacting text or images. This is the standard approach for client-side PDF editing.
Select the Image Overlay tool, click to upload your image file (PNG or JPG), then drag and resize it on the page. This is useful for adding logos, stamps, or signature images to official documents.
Select the Page Numbers tool. Choose the position (top or bottom, left, center, or right), set the starting number, and choose font and color. Click Apply to add numbers to every page at once.
True text replacement in PDF is technically complex. The Text tool adds new text over the existing content. To replace existing text, use the Eraser to cover it, then use the Text tool to add the corrected version.
For everyday needs — filling forms, adding signatures, erasing content, overlaying images, and adding page numbers — yes. Adobe Acrobat has more advanced features for print production workflows.
Adding text and images will increase file size slightly. Use the Compress PDF tool afterwards if you need a smaller file.
