Edit PDF

Edit your PDF documents directly in the browser with pdfFiller.

What is Edit Mode?

Edit Mode is a feature that allows you to edit PDF documents directly. You can access this mode via the Edit button in the toolbar. Once in Edit Mode, you can directly modify text in PDFs, which is different from using annotation tools that only allow comments or highlights. This feature is available for native PDFs only, ensuring that you can make changes without converting the document to another format.

How to Access Edit Mode

To access Edit Mode for PDF editing, click the pencil icon in the toolbar. Ensure that your document is in an editable state; otherwise, you won't be able to make changes. Supported browsers include Chrome and Firefox, and the best part is that no installation is required to start editing your documents.

Editing Existing Text in PDFs

To edit PDF documents, click directly on text blocks to make changes. You can navigate between text elements easily, and any changes you make are saved automatically. This functionality works on native PDFs only, allowing for straightforward text modification without any hassle.

Adding New Text Blocks

To add text to PDF documents, you can insert free-floating text blocks anywhere in the document. You can set initial formatting options for the new text and adjust its position easily. This feature is compatible with all document types, giving you flexibility in how you present your information.

Removing Text from PDFs

To remove text from PDF documents, simply select the text you want to delete and remove it easily. If you make a mistake, you can undo actions if needed. This feature works on both native and scanned PDFs, but ensure that the document is editable before attempting to delete any text.

Using the Whiteout Tool

The Whiteout tool allows you to cover text with a white fill rectangle. This tool is different from the Blackout tool, which permanently removes text. Use the Whiteout tool for corrections only, and it is easy to apply and adjust as needed.

Text Formatting Options

Explore available text formatting features to enhance your documents. You can change the font family and size easily, apply bold, italic, and underline styles, and select text color and alignment. These formatting options apply to both new and existing text, allowing for a polished final product.

Find and Replace Text

To locate and replace text in PDFs, use the Find & Replace tool effectively. This tool allows you to locate specific text strings quickly and replace them with new text seamlessly. Remember, this feature works on editable documents only, so ensure your PDF is in the correct format.

Navigating Native vs. Scanned PDFs

Understanding the differences between native and scanned PDFs is crucial for effective editing. Native PDFs allow full text editing, while scanned PDFs require OCR for text editing. Annotation tools are available for scanned PDFs, but font matching is not guaranteed, which can affect the appearance of your document.

Limitations of Edit Mode

Edit Mode has certain limitations that you should be aware of. You cannot edit scanned PDFs without OCR, and font matching is a best-effort feature. Additionally, password-protected documents cannot be edited, and you are limited to working with editable documents only.

Comparison with Other PDF Editors

When considering PDF editing tools, it's important to compare them. Adobe Acrobat offers extensive features but comes at a high price, making it less accessible for small businesses. Foxit is a fast and efficient PDF editing tool, but it lacks some user-friendly features that beginners might need. Nitro provides robust editing capabilities, but it has a steeper learning curve compared to pdfFiller, which is affordable and easy to use.

Next Steps for PDF Editing

After editing your PDF documents, be sure to save changes to your document. You can share edited PDFs with others easily. Explore additional features in pdfFiller to enhance your document management experience, and consider upgrading for more tools that can assist you in your workflows.

Thought it was too expensive and did not see the 70% discount for paying annually instead of monthly and do want that discount and as such a large partial refund of the $120 we were charged
Manel
Does what I need, the only thing is, it can be confusing when you try to log in, it takes you to another page instead of your actual account page so I have to search for something else to get to it, or I may just haven't located how yet, still good for what I need done.

PDF Filler is very user friendly compared to other available form typer software. After, downloading, I immediately began to fill in a job application and was able to finish expediently. Excellent tool!!!

Communication & follow through on point. Only ever used Adobe in the past. Found this affordable option. It is fantastic. User friendly and an effective app. I applied for a rental with a heap of forms to fill out and now our family are living in it. I accidentally signed up for the 1year subscription. I contacted the help desk, and advised that I only wanted to use it during the trial period for a purpose and happy to pay for one month. Their reply communication was quick and on point. They summarised and actioned exactly what I requested. Only charged me $30 for the month, refunded the difference $114 and cancelled my future subscription. I would happily use this again. Thank you very much.
Dionie Sue Toka
Cancelling a subscription can be an intimidating and anxiety creating experience. NOT WITH THESE PEOPLE!!! Today I logged in to my account. ***** linked in as my Chat contact and in less then 1 minute the subscription was taken care of for me!!!! I have had to fight too many providers about cancelling subscriptions so THIS WAS REFRESHING!!! Such a contrast and it makes me want to stay connected with them if I ever need their services again.Don't hesitate to access their services and products.

Outstanding online rep answered my questions. I reached out to one of your online chat support reps and was giving all the information needed to help me with my court brief that I'm writing. Dee sent me sample screen shots that helped me tremendously in a few areas. You got a good employee there. You should give the guy a raise.
