How to Edit a PDF on iPhone for Free
Annotate, sign, rotate, and modify PDFs on your iPhone without installing additional apps.
iPhone has built-in PDF capabilities in the Files app (Markup for annotations) and Safari (form filling). For more operations — rotating, removing pages, compressing, merging — FixMyPDF works in Safari on all iPhone models.
Built-In: Files App Markup
Open any PDF in the Files app. Tap the share icon and select Markup. Add highlights, drawings, text, and signatures. This is built-in and requires no additional tools — perfect for quick annotations.
For More Advanced Edits
In Safari, FixMyPDF tools handle: rotating pages, compressing for sharing, adding page numbers, removing pages, merging multiple PDFs, watermarking.
Signing PDFs on iPhone
Both the Files Markup tool and FixMyPDF's signature tool support adding a signature to a PDF on iPhone. The Markup approach is fastest for quick signatures; FixMyPDF gives more control over placement and size.
