PDF Editor Online — No Watermark on Output
Many free online tools add watermarks to your output — a logo, a URL, or "made with…" branding that ruins professional documents. FlexyPdf's PDF Editor never adds watermarks to your files. Every output is clean, unmarked, and ready for professional use. Whether you are preparing documents for clients, creating content for your business, or working on school assignments, your results look exactly as you intended — without any third-party branding. This is not a limited trial feature; watermark-free output is always included at no cost.
How to Use PDF Editor
Open Your PDF
Drag and drop a PDF file onto the editor, or click "Select PDF File" to browse. Files up to 50 MB are supported. The document loads instantly in your browser — nothing is uploaded.
Edit, Annotate & Sign
Choose a tool from the toolbar: add text, highlight areas, draw shapes, insert images, or place a digital signature. Click any annotation to move, resize, or delete it. Use Ctrl+Z / Ctrl+Y to undo and redo changes at any time.
Manage Pages
Use the page toolbar to rotate, duplicate, delete, or add blank pages. Drag thumbnails in the sidebar to reorder pages. Copy any annotation to all pages with one click.
Export & Download
Click "Save PDF" to embed all annotations and download the edited file. Choose "Optimize" to compress JPEG images and reduce file size. The downloaded PDF is fully compatible with Adobe Acrobat, Preview, and all standard readers.
Features
Text Annotations
Add formatted text boxes anywhere on the page. Choose font size, color, bold, italic, and alignment. Text is embedded as real PDF content — readable in any viewer.
Highlight & Draw
Highlight passages with 6 color presets, draw freehand with the pencil, or insert rectangles, circles, arrows, and lines to mark up documents precisely.
Digital Signatures
Draw your signature on a canvas pad or upload a PNG/JPG image. The signature is placed as a resizable, rotatable image annotation at the bottom of the page.
Page Management
Rotate, duplicate, delete, or insert blank pages. Reorder pages by dragging thumbnails. All structural changes use pdf-lib and preserve the original page content.
Undo / Redo History
Every annotation action is tracked in a 30-step history. Press Ctrl+Z to undo or Ctrl+Y to redo. History resets cleanly when a new file is loaded.
Optimized PDF Export
Standard export embeds annotations at full quality. Optimized export compresses JPEG images to 70% quality — ideal for reducing file size before emailing or uploading.
