完全ガイド: PDFを編集

Editing a PDF directly is a capability that many people assume requires expensive desktop software like Adobe Acrobat. iLoveDoc's Edit PDF tool breaks that barrier by providing a comprehensive PDF editing experience right in your browser, completely free. You can add text, insert images, draw shapes, highlight content, and annotate your documents without installing any software. The editor preserves the original PDF layout while allowing you to overlay new content. This is perfect for filling in forms that aren't interactive, adding notes to documents received from others, correcting small errors, inserting signatures, or marking up designs for feedback. The editing interface is intuitive — select your tool (text, image, shape, or highlighter), customize the properties (font, color, size), and click on the document where you want to make changes. All edits are saved into the PDF structure, creating a standard-compliant file that opens correctly in any PDF viewer. Since everything runs in your browser, your documents stay private and secure throughout the editing process.
