ClaroPDF is a professional and user-friendly PDF viewer, reader and annotator. Annotate, mark up and save PDF files which are then still fully compatible with Adobe Reader and other popular PDF apps.
+ Annotations, Notes and Comments
ClaroPDF includes a powerful Annotation toolbar that lets you add notes and other comments. These are fully interchangeable with Adobe Reader and most other popular PDF apps, so your ClaroPDF comments will still be there if you open the PDF on another device. Annotations created in another PDF app can also be viewed and edited.
Annotation features include: highlight; underscore; strikeout; notes; free text (type straight into the PDF); free line draw (with many colours, opacity and thickness control); shapes (circle, square, line - with many colours, opacity and thickness control); images (you can even insert photos from your iPad camera or photo library into the PDF file)
+ Speech, Productivity and Accessibility
ClaroPDF has access to the full range of iOS system voices and a range of synchronised colour highlighting options. A ‘Speak in Background’ option lets you listen to a PDF while viewing another app - great for proofreading accessible text PDF files while you’re working in other apps. The ‘Speak on tap’ (either from the tapped sentence or the page’s first sentence) and ‘Stop on tap’ options make speech easy to control.
ClaroPDF allows the background colour of the PDF to be changed, to enhance readability. ClaroPDF fully supports VoiceOver. Image PDF files cannot be spoken by ClaroPDF voices, but can still be fully viewed and annotated.
+ Smart Zoom
On double-tap, ClaroPDF will identify the tapped text block and perform an intelligent zoom on it, just like in Safari. This reduces how much you have to adjust the zoom manually.
+ Full-Text Search & Navigation
Search will highlight all found results in your document and let you jump to each one in turn. ClaroPDF shows each page of a multi-page PDF document as a thumbnail, allowing for faster scrolling of long documents. The thumbnails automatically hide when not needed.
+ Managing PDF Files
PDF files can be opened in ClaroPDF from all other apps, including Mail and Safari. All opened PDF files will be placed in the ClaroPDF Documents List for later viewing. You can also open files from Dropbox, Google Drive, or import files via iTunes. PDF files can be saved into ClaroPDF’s Documents, Dropbox or Google Drive, sent by email, or opened in other apps that support PDF files. ClaroPDF offers the option to email or forward the PDF in a 'flattened format' with annotations made permanent, or send the whole file with editable annotations for further review by others.
+ Fullscreen mode
Allows the full document to be seen without toolbars in view. Ideal for smaller screens!
ClaroPDF allows the background colour of the PDF to be changed, to enhance readability. ClaroPDF also fully supports iOS VoiceOver.
+ ClaroPDF vs ClaroPDF Pro
ClaroPDF includes many great features, however, here is a list of what’s only included in ClaroPDF Pro:
* 4 Nuance Vocalizer text-to-speech voices included as standard.
* Multimedia: add audio and video files to pages of your PDF file.
* Folder customisation in the PDF documents list: allows you to organise all your PDFs into different folders.
* Sync with iCloud: sync your PDF files between devices.
* Save as PDF app extension: convert text, images and web pages to PDF files from other apps such as Safari. Great for keeping a PDF record of that order confirmation web page!
* In-app purchases to add more Vocalizer voices and OCR credits.

Ratings and Reviews
Feature packed FAR from polished.
I use an iPad on the latest update and downloaded this as an easy way of editing a PDF. For a free app it's ok, it has the basics but it has issues with saving files. I just spent three hours on a document, tried to save it using the "save as" function on the 'download?' menu and it erased EVERYTHING! I got an error saying that the file isn’t a PDF or was corrupted 😤🤬🤯 I’m really trying not be unfair here btw.
Anyway, if you don’t want to die from the stress of losing three hours of work, here's a tip: save your files to where you originally downloaded it from using the 'export' menu.
