Best App to Insert PDFs on My Phone in 2026

Adobe Acrobat on mobile lets you view, annotate, edit text and images, organise pages, and sign documents from your phone. Standard costs $14.99 per month on an annual plan, while Pro costs more and adds bulk signature sending, web forms, and templates. The free Reader app covers viewing and basic annotation, so you can test the mobile workflow before paying. The strength is completeness. Page insertion, text edits, image placement, and signature capture all live in the same app, and files sync through Adobe cloud storage or linked services such as Google Drive and Dropbox. The weakness is price. If you only insert a page now and then, a free app will do the same job. Pay for Acrobat when you edit PDFs every week and need the edits to hold up when clients open them in Acrobat on desktop.

PDF Expert, from Readdle, is a well-regarded PDF editor for iPhone, iPad, and Mac. On a phone you can annotate, fill forms, sign, edit text and images, and manage pages, including inserting and reordering pages in a document. The interface is clean and fast, and it works well with a stylus on iPad, though phone use is mainly touch-based. The main limit is platform. PDF Expert does not offer an Android app, so Android users need a different pick from this list. Pricing varies by plan and storefront, with yearly and one-time options listed, so check the current price inside the app or on the official site before buying. For iPhone users who edit PDFs often, it is one of the smoothest mobile editors available.

Foxit PDF Editor covers Windows, Mac, iOS, and Android, so you can start an edit on a phone and finish it on a computer. The mobile app supports annotation, form filling, signing, and page tools, along with text and image edits for common jobs. That cross-platform reach is useful for teams where some people use iPhones and others use Android phones. The trade is that the mobile app does not include every desktop feature, and pricing varies by platform and plan, so the price you see for desktop may not match the mobile subscription. Check the mobile plan details in the app store listing before you pay. Foxit suits users who want one PDF editor across devices and do not want to be tied to a single phone platform.

PDFelement, from Wondershare, is a full PDF editor with apps for Windows, Mac, iOS, Android, and the web. On a phone you can edit text and images, manage pages, fill forms, and sign, while the desktop app adds deeper batch tools. The yearly single-platform plan starts at $79.99, with multi-platform plans that add mobile and web access at a higher yearly price. A useful extra is OCR, which turns a scanned page into searchable and editable text, and an AI sidebar that can summarise or translate a document. AI use is limited per plan, with extra credits available, so heavy AI users should check the allowance. PDFelement suits users who work with scanned documents and contracts on a phone and want OCR in the same app as page editing.

Xodo lets you edit, annotate, sign, and share PDFs on desktop, mobile, and the web. On a phone you can fill forms by typing into fields, tap to sign with a finger or stylus, add comments, and manage pages for common jobs. The core app is free, which makes it a good first try for anyone who only needs occasional edits. The limit is depth. Xodo covers the daily jobs well, but advanced text editing, OCR, and batch tools sit behind paid plans or are handled better by Acrobat or PDFelement. For inserting a page, adding a signature, or filling a form on a phone, Xodo is often enough, and the lack of a subscription for core use is a clear advantage over paid-only editors.

PDFgear is a free PDF editor that covers editing, annotation, conversion, and page management without a subscription for its core features. On a phone you can open a PDF, add text or images, annotate, sign, and organise pages, then save and share the result. The app also runs on desktop, so you can move a file between phone and computer without paying for a second tool. The strength is value. Reviewers often cite PDFgear as a way to avoid a subscription for essential PDF work, and the free model suits students and casual users. The weakness is ecosystem size. It does not match Adobe for enterprise integrations or for large-team admin tools. For personal use and small-team edits on a phone, that gap rarely matters, and the price is hard to argue with.

Smallpdf started as a web tool for quick PDF jobs and now offers mobile apps as well. It is best for simple insert-style tasks, such as merging two PDFs into one, splitting a file, compressing a large file, or converting a file to another format. The interface is simple, with one job per tool, which helps when you need a result fast on a phone browser. The limit is free use. The free tier has daily limits on tasks, and deeper editing, OCR, and batch work need a paid plan, with pricing listed on the official site. Smallpdf suits occasional jobs where you already have the file on your phone and just need to combine, split, or compress it. For heavy text editing or page-by-page work, Acrobat, PDFelement, or PDF Expert fit better.

iLovePDF offers a set of focused PDF tools, including merge, split, compress, convert, and page organisation, through its website and mobile apps. On a phone, the merge tool is the closest match to inserting one PDF into another, since you can combine files and reorder pages before saving the result. The interface is plain and task-based, so you do not need to learn a full editor to finish a job. The free tier covers basic tasks with limits, while Premium adds higher limits and extra features. The weakness is editing depth. iLovePDF will not replace a full editor for changing text inside a scanned contract or for complex form work. Use it when your job is to combine, split, or tidy pages, and use a full editor from this list when you need to change the content inside the pages themselves.
