Adobe's PDF format has been one of the greatest inventions of our times, enabling fast exchange of documents in pristine order – preserving the look of a file just as they should be.

While the entire thing about PDF files is good, the complexities involved in creating and editing PDF files still looms at large for those of us who can't afford the entire Adobe suite.

For the Mac, Windows and Linux PCs, there have been a number of alternatives that allow you to create PDF files, edit them, splice them etc.

Don't Miss: Best PDF Editors for Mac

But when it comes to the iPhone, iPad or other iOS devices, options appear to be very limited. In fact, from a set of a dozen so-called PDF editors on the App Store, we found that only four of them are really worth the effort and most importantly, the money.

Top 5 PDF Editor Apps iPhone and iPad to Edit PDF Files:

1. Good Reader

Good Reader App for iPhone and iPadPrice: 4.99
Good Reader for iPhone (and iPad, separately) is probably the best solution when it comes to notating PDF files. It's not a PDF file per se but it can be used as a PDF editor. Here's how:

  • You can annotate the PDF files you read on Good Reader. Annotations include sticky text, highlights, lines, arrows, circles, typewritten/hand-drawn notes etc
  • Now, save or sync the annotated PDF file to Dropbox/Drive/SugarSync (read more about Cloud storage apps for iPhone here)
  • Open the document anywhere else: on another iDevice or PC and you'll find that the PDF contains all the annotations you've made.

Sure, it's not a direct edit method but if this is all you're looking for, why shell out a lot on other editors? Good Reader costs about $4.99 and has different versions for the iPhone and iPad.

2. PDF Reader Pro

PDF Reader Pro iPhone App

Price: $5.99
Despite the name, PDF “Reader” Pro actually lets you edit, modify and annotate PDF files. The app was listed by Apple under iPhone App for Business and I guess that's probably quite enough of an introduction you'd need. PDF Reader Pro also combines efficiently the features of “PDF Slicer” (below) and brings a complete PDF editing experience.

3. WritePDF

WritePDF iPhone App

Price: 6.99 – a hefty but justified price.
WritePDF is a simplified albeit enormously powerful PDF editing and annotating tool. It can handle a variety of formats too including spreadsheets and comes with a built-in PDF creator. Again, the basic idea is to modify the PDF than edit it in totality. You also get the ability to fill PDF forms which makes signing documents easier with this app.

How to get files:

  • You can edit PDF files, add text on to them, add links etc.
  • Share through email, or other SFTP methods.
  • Support for iCloud, Dropbox lets you sync documents easily

4. Documents Unlimited Office & PDF Editor

Documents Unlimited Office & PDF Editor for iPhone

Price: $3.99
This app isn't all that into PDF editing but brings a decent set of PDF editing capabilities. From the official account of the app makers, it is clear that the app has a hit-or-miss chance of opening PDF files and editing them successfully. The app is focused more on documents so it's a fair game here. Cloud support allows you to easily export files.

5. PDF Slicer

PDF Splicer iPhone App

Price: $4.99
PDF Slicer is just that: a slicer for PDF files. You can:

  • Cut or delete entire pages off PDF files
  • Add or merge pages into PDF files
  • Crop, copy and paste out of PDF files

You can't edit the contents (text, images, links etc.) but all that you can do are page-based functions.
