Best App to Insert PDFs on My Phone in 2026: 8 Apps Compared

Adobe Acrobat is the default choice for many phone users because files made in Acrobat open cleanly almost everywhere. On mobile, you can view, annotate, fill forms, add text, insert pages from other files, and sign documents. That range matters when a PDF arrives by email and needs a fix before it goes back.

The free Reader covers viewing and basic annotation, while Acrobat Pro starts at $19.99 per month and adds full editing, conversion, and more signing tools. If you only insert a page now and then, start free and upgrade only when a paid feature blocks you.

PDF Expert is built around doing PDF work quickly on an iPhone or iPad. You can reorder pages, insert new pages, add text and images, highlight, and sign, all with a layout that stays readable on a small screen. For someone who handles contracts or school forms on an iPad, that focus shows.

The app is free to download with basic tools, and a subscription adds full editing and advanced features. Check the current in-app price before you subscribe, since app store pricing can differ by region and plan length.

Foxit suits a user who starts a document on a computer and finishes it on a phone. The free reader handles viewing and basic annotation, while PDF Editor adds page organization, text editing, forms, conversion, and OCR for scanned pages. That makes it a solid pick for work files rather than one-off reads.

PDF Editor costs $129.99 per year for individuals in the pricing we found, with a higher tier adding mobile access and e-signature envelopes. Confirm the tier that includes mobile editing before you buy, since reader and editor are not the same product.

PDFelement, from Wondershare, is a full editor rather than a simple reader. On mobile you can insert and reorder pages, add text and images, annotate, fill forms, and sign. OCR helps when the page you need to insert comes from a scan rather than a clean digital file.

Pricing is listed by platform and plan on the vendor site, so we list it as See website rather than guessing a single mobile price. Try the trial with a real file, especially a scanned one, before committing to a yearly plan.

iLovePDF is a good pick when the job is simple: combine two PDFs, insert pages, split a file, compress it, or convert it. The task-based layout means you pick the job first, upload the file, and get a result without learning an editor. The mobile app covers the common tasks, and the website covers the rest.

The free tier handles occasional use, while premium removes limits and adds more processing. If you need deep text editing or form design, pair it with a full editor rather than forcing iLovePDF to do that job.

Smallpdf takes a similar task-first approach to iLovePDF, with a clean layout that suits a user who does PDF work a few times a month. You can merge files, organize pages, add a signature, compress a large file, and convert to and from PDF. The mobile app keeps the most common tools close at hand.

Free use has daily limits, so a user who processes files all day will hit a wall. Check the current Pro price on the Smallpdf site before upgrading, and use the free tier first to confirm the exact tool you need is included.

Xodo is a strong free-first option for reading, marking up, and organizing PDFs on a phone. You can annotate, fill forms, add signatures, and manage pages, and cloud sync helps when a file moves between phone and computer. For students and field workers who mark up documents daily, that free depth matters.

Paid tiers add more editing and collaboration features, so check what your workflow needs before paying. If your main job is inserting pages and signing, the free tools may already cover it.

PDFgear stands out because it offers a wide editing set for free, including page management, text and image editing, annotation, and signing. That makes it worth trying before paying for a subscription, especially for a user who inserts pages or images a few times a month.

The trade-off is scale. PDFgear does not have the same enterprise support footprint as Adobe or Foxit, and some advanced tools work best on desktop. For everyday phone editing, though, it is a genuinely useful free option, and it is easy to test with a copy of a file first.
