Short answer: on an iPad you can run LaTeX in two ways. You can edit and compile in the browser with Overleaf in Safari, which needs a connection, or you can use an app with an on-device typesetter, which can compile without a connection but ships a smaller package set than a full TeX distribution. This guide compares the two for a researcher who needs to write, compile and cite on an iPad, and flags where an iPad changes the behaviour you expect from a laptop. The same applies whether you search for latex ipad, ipad latex, latex for ipad or latex in ipad.
What it is used for in research
Researchers use LaTeX for manuscripts, theses and slides that contain equations, cross-references and managed bibliographies. On an iPad the usual jobs are drafting while travelling, making small edits to a shared manuscript and checking that a compile still succeeds. The decision that matters is where the compile happens: on a remote server (Overleaf, or an app’s cloud typesetter) or on the device itself.
Install or access (official source only)
Overleaf in Safari (no install)
Overleaf is used through the browser. Its documentation states that it supports versions of Chrome, Firefox, Safari, Microsoft Edge and Firefox ESR released in the last 12 months, and that there are some limitations when using Overleaf on a mobile device or tablet (Overleaf documentation, supported browsers, checked 2026-11-07). Keep iPadOS and Safari up to date so you stay inside that window.
On-device editor apps
Apps are installed from the App Store. Texpad, now listed by Texifier, has an archived help guide (Texpad Help v1.4 on texifier.com, checked 2026-11-07) that describes its local and cloud typesetters; the examples below come from that archived guide and may differ from the current release. Other App Store editors exist, and TeXShop, often mentioned in searches, is a Mac application and is not an iPad app. Check each app’s own App Store listing for its current features and system requirements before relying on it.
Step-by-step task: compile a manuscript on an iPad
Option A: Overleaf in Safari
- Open Safari on the iPad and sign in to your Overleaf account.
- Open the project and use Recompile to build the PDF.
- If the PDF viewer stays blank, which Overleaf attributes to an older browser version, switch the PDF viewer setting to Browser under File > Settings > Editor, then recompile.
Option B: an app with an on-device typesetter (Texpad guide as the documented example)
- Create or import the project into the app. If you store files in Dropbox, the guide says a Dropbox account is required.
- Choose Local Typeset to compile on the device, or Cloud Typeset to compile on the vendor’s servers.
- Use the PDF button to view the output and the Log button to read errors and warnings.
Output and how to read it
In Overleaf the PDF appears beside the source. With the viewer set to Browser, Overleaf notes three limits: the SyncTeX jump-to-preview and jump-to-source arrows do not work, each recompile returns to the first page of the PDF, and Overleaf’s own PDF navigation controls are unavailable, so you use the browser’s controls instead. In the app, the log is the place to look when a compile fails; start with the first error, since later messages are often consequences of it.
Cloud versus on-device: decision table
| Question | Overleaf in Safari | On-device typesetter (Texpad guide) | App cloud typesetter (Texpad guide) |
|---|---|---|---|
| Where does the compile run? | Overleaf’s servers | On the iPad | The vendor’s servers |
| Works without a connection? | No, it is a web application | Yes, the typesetter runs natively on the device | No |
| Engines | Chosen in the project settings | pdflatex and bibtex | Adds XeLaTeX, pLaTeX and biber |
| Package coverage | Server-side TeX distribution | Smaller than a full LaTeX distribution | Server-side |
| Is your source sent off the device? | Yes, projects live on Overleaf | No | Yes; the guide states files are deleted from the vendor’s servers immediately after the typeset |
The practical consequences, which are an editorial reading of the table: choose the on-device route when you must work offline or do not want unpublished source leaving the device; choose a server route when your document needs XeLaTeX, biber or packages the local set lacks.
Bibliographies on an iPad
Because the Texpad guide lists biber only for its cloud typesetter, a project that uses BibLaTeX with the biber backend will not compile locally in that app, whereas classic BibTeX will. Which one your project uses is set by the bibliography commands in the source. See LaTeX bibliography styles explained for the difference between BibTeX and BibLaTeX/biber, and how to convert a DOI to BibTeX for building the .bib file.
Troubleshooting
- Blank PDF in Overleaf: use the Browser PDF viewer setting described above, and accept the three limits listed there.
- Package not found on-device: the guide says the local package list is not as comprehensive as a full LaTeX distribution; compile with the cloud typesetter or move to Overleaf.
- Bibliography missing or unresolved: check whether the project uses BibTeX or biber and compile with an engine chain that supports it.
- Collaborators or history: see LaTeX and Overleaf collaborative writing.
Free alternatives
| Option | Where it runs | What is documented |
|---|---|---|
| Overleaf free plan | Browser (Safari) | One collaborator per project, document history for the previous 24 hours only, Basic compile-timeout tier (Overleaf plans page, checked 2026-11-07) |
| Papeeria | Browser | Real-time co-editing, free sign-up with no credit card required, real-time collaboration, project download as a ZIP archive for offline work with a local TeX distribution (papeeria.com, checked 2026-11-07) |
| Texpad local typesetter | On the iPad | pdflatex and bibtex without sending files off the device (archived v1.4 help guide) |
For more browser-based options see Overleaf alternatives for collaborative LaTeX. Plan terms change, so check the vendor’s page for current limits.
FAQ
Can I run LaTeX on an iPad?
Yes. Use Overleaf in Safari, or an App Store editor with an on-device typesetter.
Can I use LaTeX on an iPad without internet?
Only with an app whose typesetter runs on the device. Overleaf is a web application and needs a connection.
Is there a free way to use LaTeX on an iPad?
Overleaf offers a free plan with the limits listed above, and Papeeria states that sign-up is free. Check each vendor for current terms.
Does TeXShop run on an iPad?
No. TeXShop is a Mac application.
Is it safe to compile an unpublished manuscript in the cloud?
Any server route transmits your source. Read the vendor’s privacy statement, and use an on-device typesetter if the source must stay on the device.
