Safari shows PDFs nicely. It opens them inline, lets you scroll, save, print. The 'edit' button is conspicuously missing. On Mac, Safari hands PDFs off to Preview for editing; on iPhone, Safari hands them off to Files. The browser itself doesn't edit.
Safari's PDF handling
On Mac, click a PDF link in Safari and it opens in the tab. From there, you can download, AirDrop, or print — but not edit. To edit, save and open in Preview (annotation only) or use a web app for real text edits.
Flint is the web app. Drag the PDF onto a Flint tab; edit inline; download. No extension, no Mac-specific app.
Cross-device with Safari
Same Flint URL works on the Mac, iPhone, and iPad. Safari syncs tabs via iCloud — open Flint on the Mac and it's already loaded on the iPad. Useful for starting a quick edit on one device and finishing on another.
Most PDF work doesn't need that, but the option's there.
Reader mode and PDFs
Safari's Reader View doesn't apply to PDFs (it's for web articles). For 'cleaner' PDF reading, the PDF itself needs editing — that's where Flint helps. Delete unwanted pages, reorder, compress for a tidier file.
FAQ
Does Safari have built-in PDF editing on iOS?
No. Safari opens PDFs; Markup (in Files) annotates them. For real text edits, use a web app like Flint. Safari is the browser; Flint is the editor.
Are Safari PDF extensions worth using?
Safari has fewer PDF extensions than Chrome. Most that exist redirect to web apps anyway. Going direct to Flint is usually faster.
Will Flint work in Safari private browsing?
Yes. Private browsing doesn't affect Flint's functionality. Files don't persist anywhere after the session.
Safari for reading PDFs, Flint for editing them. Same browser tab, no extra app.
