What's New in PDF Viewer by Nutrient

2026.11

September 11, 2026

This update makes complex documents appear faster, improves AI Assistant conversations, and fixes issues with annotations, sharing, forms, and PDF rendering. Here’s the full list of changes: • Adds an Advanced setting to stop taps on the status bar from jumping to the first page and losing your reading position. • Shows complex PDF pages progressively while they render, so content appears sooner. • Improves on-device AI Assistant follow-up answers and reliability in long conversations. [Pro] • Fixes annotation changes sometimes being lost when the app moves to the background. • Fixes issues editing free text annotations when the window is resized or the annotation is rotated. • Fixes crashes and other problems when sharing documents, including sharing files with very long names more than once. • Fixes several form-filling and PDF JavaScript issues. • Improves rendering of transparency, blended colors, gradients, annotation text, and form field text. • Fixes redaction issues that could remove unrelated text or place the redaction box incorrectly. [Pro] We’d love to hear your feedback! If you have ideas or feature requests for future versions of the app, feel free to let us know. You can contact us using the in-app Support button on the settings screen. If you enjoy the app, please write us a review and help spread the word! Thanks!

Good replacement for the files app, recently encountering major annotation issues

For most documents it works well it serves as a much better replacement for the files app considering larger files can be opened and edited easily. Unfortunately sometimes it fails at making outlines for documents and I have recently had problems where my bookmarks and annotations haven’t saved. This problem started maybe 3 weeks ago for me. I downloaded several new pdfs and some of my annotations have saved on one of the pdfs but none of the bookmarks. Last year it worked fine with editing a 90 MB textbook, but it is failing with a pdf file of a size less than 20 MB now.

Regarding pdf viewer

I have been using this app from last 1 year for my IPad. This app is simply great. Features are also great. Many simple tasks can be completed through this. Some developments still needed. After using highlights features when I opened the pdf in different pdf viewer the highlighted portion looks little dark and strength of the letters felt less. Another problem with highlighter is that no auto straightening of highlighted portions. Except these I find everything good

Great app! Feature request.

I have been using this app heavily for many months now. It become my goto for reading and annotating research papers. Feature request: a) Please add a setting to use the file name as the tab name. I just don’t understand why this is not the default. Some journals and sites transform the pdf, so the title embedded in the pdf may be meaningless, or the author used a nonsensical name like chapter. I can’t control that, but I can rename files to have meaningful names. When I have 10 tabs open and none of the tabs are named after the filename, I am unable to find or copy that file a second time easily from a directory containing hundreds of files. b) In the share/export dialog, the label has very low contrast and is difficult to see. c) When in dark mode, the highlight drawn with the brush is not visible. It shows only in light mode. d) Please add an option to open file in existing window as new tab when I open a file from the files app. e) Had to write this into a review because the in app/on website feed back option was not found. Thanks a lot and keep up the great work. I promise I’ll be back with the remaining star.

My PDF viewer

I greatly enjoy this App, I have been using for years now. The features are very useful, the App helps me navigate easily on documents, it can also be enhanced with color options in the “note” feature. I definitely recommend it, it’s one of the best out there when it comes to working with PDF documents

It will delete your files!

Don’t put your PDF files in the default folder because if you uninstall the app, it will delete the contents of that folder.

I don’t RENT software. I subscribe to magazines and newspapers. Their content completely changes warranting a subscription. Apps, once released don’t change ‘completely’, so a subscription NOT justified nor ethical. Just cheap capitalism and dumb people.
