Select the field type option from the top toolbar, tap on the page where you need it, and start filling in your details. Simple as that!

Add text, images, links and more 

Enhance your documents by adding some of the most common elements:

  • Add Text: Quickly add new text to your PDF document for last-minute changes and updates to your reports while on the move.
  • Add Pages: Insert blank pages to your PDF. You can add PDF pages from different sources, allowing you to work with different types of content.

Add text to PDF on mobile

As an added convenience, you can customize the main toolbar to access the tools you use the most to make quick additions to your PDFs whenever you need to.

Scan and edit any document 

Xodo makes scanning documents on iPhone or Android as easy as taking a picture – and even easier with the auto-shutter feature! 

Once you have the Scan Document tool opened, just hold your phone over the paper document and Xodo will scan it for you. 

Scanning document on mobile

Once the image is scanned, you can crop your content, optimize the image quality, perform OCR, and rotate or rearrange the pages as needed.

Merge PDF, crop, rotate, and delete pages

The quickest way to access these editing tools is through the More Actions menu. Under the list, tap on any of the tools to start editing your PDF.

  • Merge PDF files: Combine and merge multiple PDF files in seconds. Start by selecting your files or adding them to the listed files with the Add Files button. You can rearrange the order of your PDFs so that all the merged content is in the correct order.
  • Crop PDF: You can crop individual pages simply by tapping and dragging the crop box that surrounds the page. You also have the option to apply a specific crop to All Pages or just Odd Pages. Either option makes cropping out wide margins and empty spaces easy, letting you create more concise and focused content.
  • Rotate Pages: Easily rotate pages to fix the orientation of your document. You have full flexibility to rotate individual pages either Left or Right and then preview the results to ensure all pages are oriented the correct way.
  • Delete Pages: Get rid of unnecessary PDF pages using the Delete Pages tool. Tap and select pages you want to delete - it doesn't get any easier.
Merging files on iOS and Android

Flatten and compress PDF

With Xodo, you can flatten a PDF to combine all the existing layers (graphics, text, annotations, and form fields) into a single unified layer, making the entire file unmodifiable. A perfect hack for quickly securing and sharing your PDFs.

You can also significantly reduce the size of your PDF file without loosing quality with the Compress PDF functionality.

Compressing PDF on mobile

Simply choose the compression level that best suits your needs. By compressing your file, you can more easily share it via email or on the web.

  • Low - smaller file size
  • High - larger file size

Redact content and add passwords

The Redaction tool (pro feature) gives you flexible options to black out content. You can permanently redact blocks of content, selected text, an entire page or page range, and even search & redact specific text in your document.

Redacting PDF content on mobile

In addition to redacting content, you can quickly add passwords to your documents in a clutch. Use the Protect PDF to add a secure password and save the protected PDF. You can also remove passwords, if needed.

Convert images to PDF

The Image to PDF tool is your one-stop shop to turn images to PDF on your smartphone.

Select your image and Xodo will instantly set it up for conversion. You can also use the pro option to reduce file size and recognize text (OCR), and to either convert multiple images separately or merge them into one PDF file.

The result? Quick and easy conversion without losing the original quality of the image.

Save and share your edited PDF 

Now that you are done editing your PDF, it's crucial to save your revisions. Xodo can accommodate the way you store files on different cloud platforms.

If you’re using the Android app, your file changes will automatically be saved to your local drive, and you have the option to save an extra copy on Xodo Drive.

In addition, if you’re using Xodo Drive, you can instantly share your PDFs with other colleagues on your team. And, you can also access Xodo Drive and edit your documents on the web from your desktop.

When you edit PDF on iOS, your processed files will be saved to your device or can be stored on your other cloud services.

For now, Xodo Drive is not available on iOS. But both the mobile and online apps integrate support for Google Drive and Dropbox, so you can easily access the PDFs you edited on your iOS device.

Edit your PDFs from anywhere with Xodo

Edit your PDF files and switch between different devices without missing a beat. Xodo seamlessly integrates cross-platform access to the PDFs you’ve been editing.

When you save your files to Xodo Drive, your account is synced online, allowing you to pick up where you left off effortlessly. All you have to do is log in and continue working.

Our Xodo PDF editor app lets you do it all. But don’t take our word for it. With over 4.6-star ratings on iOS and 10+ million downloads by Android users alone, Xodo is a top choice for managing and editing PDFs remotely, on-the-go, and for free.
