Open the PDF in Safari and edit it right there. No App Store download, no account, and nothing uploaded over mobile data.

To edit a PDF on an iPhone free, open the file in Safari, tap it into the editor above, then tap to place text, draw with a finger or Apple Pencil, sign, and download. No app installs and nothing uploads — the PDF is edited on the phone itself, so it works on mobile data without burning any. The built-in Files app can already mark up and sign a PDF; come here for the things it can't do, which are merging documents, reordering pages and compressing to a size limit.
Tap the file in Files, Mail or Messages, then share it into this page — or open the page first and pick the PDF from Files.
Place text with a tap, draw or hand-write with a finger or Apple Pencil, sign, highlight, white out, and reorder or delete pages.
Tap Download — the finished PDF saves to Files, ready to attach to an email or upload to a portal.
A contract lands in Mail and needs a signature back before you're at a desk.
Compress a photographed document to under 1MB before uploading from the phone.
Type into a flat form the Files app gives you nowhere to type on.
Combine pages captured with the camera into one document to send.
iOS is better at PDFs than it gets credit for. Open a PDF in Files and the Markup toolbar gives you freehand drawing, highlighting, shapes and a stored signature, all free and already on the phone. If marking up or signing is the whole job, use Markup and skip this page — it's faster.
The gaps show up the moment a document needs restructuring. Files won't merge two PDFs into one, won't let you drag pages into a new order, won't crop a page, and won't compress to a stated size limit — which is exactly what an application portal asks for when it rejects your upload for being 4MB.
This editor covers those in Safari without an install. It matters more on a phone than on a desktop: an App Store download for a one-off signature is a poor trade, and uploading a passport scan to an unknown PDF service over mobile data is a worse one.
Continue your PDF workflow: Edit PDF on Mac — The same tools in desktop Safari., Sign PDF — Draw a signature with your finger. or Compress PDF to 1MB — Fit a portal limit before uploading.
Draw your signature directly on the screen with a finger or Apple Pencil, drag it onto the signature line, and download the signed file to Files. No printing, no scanning, no photographing a signed page at an angle in bad light.
The signature never goes to a server — it is drawn and embedded on the phone. That matters for the documents people actually sign on a phone: offers, leases, contractor agreements and anything carrying bank details.
The same editor runs in iPadOS Safari, and the extra screen makes page management genuinely comfortable: drag thumbnails to reorder, crop with a larger target, and hand-write with an Apple Pencil at a natural size. Split View works too, so you can keep the source document open beside the editor while you copy details across.

Open the PDF in Safari and use the editor above — tap to add text, draw, sign, highlight, reorder pages or compress, then download to Files. There is no app to install and no account to create.
Partly. Files includes Markup, which draws, highlights, adds shapes and applies a saved signature. It cannot merge PDFs, reorder pages, crop or compress to a size limit — those are the reasons to use a browser editor instead.
Yes. Draw the signature on screen with a finger or Apple Pencil, drag it onto the line and download the signed PDF. It is embedded on the device, so the document is never uploaded.
Yes. The draw and signature tools follow an Apple Pencil precisely, which makes hand-writing on a form or initialling pages practical rather than a smudge.
Only to load the page itself. The PDF is processed on the phone, so a 40MB document costs no data — unlike upload-based tools, which send the whole file up and pull it back down.
To your Files app via Safari's normal download, so you can attach it to an email, upload it to a portal or move it to iCloud Drive like any other file.
No. Editing happens inside Safari on your device — the file never leaves the phone, so nobody, including us, can see it.
