Edit PDF Online Free - PDF Editor & Annotator

You can add new text boxes anywhere on your document to overlay or supplement existing content. Editing the original embedded text depends on the PDF structure, as some documents were created with editable text layers while others, particularly scanned documents, contain only images. For PDFs with flat text layers, you can add correction boxes with matching fonts and colors to effectively modify content. Our editor provides font matching tools to help your additions blend seamlessly. For scanned documents, use our OCR PDF tool first to create a text layer, then edit the recognized content. All editing happens locally in your browser for complete privacy.

For the best signature experience, we recommend using our dedicated Sign PDF tool, which offers specialized features for creating, positioning, and saving electronic signatures. However, you can also create signatures directly in the PDF editor using the drawing tools to handwrite your signature with a mouse, stylus, or touchscreen. The dedicated signature tool offers advantages like font-based signature generation, signature saving for reuse across documents, and optimized placement controls. After signing, consider using our Flatten PDF tool to permanently embed the signature, preventing others from easily editing or removing it. All signature creation and document processing happens locally in your browser.

Scanned documents are essentially images embedded in a PDF wrapper, so the "text" you see is not actually editable text data. To edit scanned content, first use our OCR PDF tool to perform optical character recognition, which analyzes the images and creates a searchable, editable text layer. After OCR processing, you can select, copy, and edit the recognized text. Alternatively, you can use our editor to add text boxes, shapes, and annotations on top of the scanned images without OCR. For the best OCR results, use high-resolution scans (300 DPI or higher) with clear, printed text. All processing happens locally in your browser for document privacy.

Yes, our PDF editor is completely free with no watermarks added to your documents, no registration or account required, and no limits on how many documents you can edit. Unlike competitors that restrict free users to basic features or a limited number of edits per day, ContinuePDF provides full editing functionality without any cost. You can add text, images, shapes, highlights, annotations, and more without hidden fees or premium tier restrictions. There are no file size limits imposed by our service, though very large files may process more slowly depending on your device's capabilities. All processing happens locally in your browser for maximum privacy and security.

Yes, you can insert images anywhere in your PDF document using our editor. Supported image formats include JPG, PNG, GIF, and WebP, with PNG recommended for images requiring transparency. Simply click the image tool, select your file, and click anywhere on the page to place it. You can then resize, rotate, and reposition the image as needed. Images are useful for adding logos, photos, stamps, or graphical elements to your documents. For best results, use appropriately sized images since very large photos may increase file size significantly. After adding images, use our Compress PDF tool if you need to reduce the final file size.

Edits are not auto-saved to protect your privacy since all processing happens locally in your browser without server storage. To preserve your changes, you must download the edited PDF when finished. We recommend downloading periodically during long editing sessions to create save points you can return to if needed. The downloaded file contains all your edits permanently embedded. If you close the browser tab without downloading, your changes will be lost because no data is stored on our servers or in browser storage. This privacy-first approach means your documents and edits are never uploaded to any external server and remain completely under your control.

Yes, you can undo recent changes while editing using the standard keyboard shortcut Ctrl+Z on Windows and Linux, or Cmd+Z on Mac. Each undo step reverses your most recent action, and you can undo multiple times to step back through your edit history. The redo function (Ctrl+Y or Cmd+Shift+Z) restores undone changes if needed. Note that the undo history is cleared when you close the editor or refresh the page, so download your work before leaving. For significant edits, consider downloading intermediate versions as checkpoints. Once you download and close the editor, the edit history is not preserved in the downloaded file since it contains only the final result.
