Edit PDF files online for free with Breklo. Add text, draw with a pen, highlight passages, insert signatures, add shapes, and embed images directly into any PDF — all in your browser. Our free PDF editor is faster than Adobe Acrobat and works on every device. No signup, no watermarks, no file size limits, completely private.
PDFs are designed to preserve formatting, which makes editing them traditionally difficult. Adobe Acrobat Pro costs $239.88 per year, and most free PDF editors either watermark your output, limit file size, or upload your documents to suspicious servers. Breklo solves all these problems with a fully-featured browser-based PDF editor that handles text, drawings, signatures, highlights, shapes, and images — completely free, completely private, and works on any device including phones and tablets.
Our online PDF editor supports adding text in 20 fonts including Inter, Georgia, Pacifico, Dancing Script, and Great Vibes. Draw freehand with adjustable colors and stroke widths. Highlight text passages with customizable colors, opacity (0-100%), and optional borders. Add signatures by drawing on the canvas or typing your name in handwriting fonts. Insert rectangles, circles, ellipses, triangles, lines, and arrows. Embed images and resize, rotate, or reposition any element. Every annotation is editable — drag to move, drag corners to resize, drag the rotation handle to rotate.
Breklo includes a full electronic signature feature. Draw your signature with mouse, trackpad, or touchscreen — the canvas captures at 2× resolution for crisp output. Alternatively, type your name in beautiful handwriting fonts like Dancing Script or Great Vibes. Signatures save as transparent PNG images that overlay perfectly on any background. Sign contracts, legal documents, employment forms, NDAs, and tax documents without printing — eco-friendly, paperless, and legally binding in most jurisdictions.
All editing happens locally using pdf-lib and pdf.js running in your browser. Your PDFs never upload to our servers, never get cached anywhere, and never persist after you close the tab. This makes Breklo the most secure online PDF editor — ideal for confidential contracts, legal documents, financial records, medical files, and any sensitive PDF you need to modify without exposing it to third parties.
Our PDF editor works on Windows, Mac, Linux, ChromeOS, iPhone, iPad, and Android. No software to install, no subscriptions to manage, no accounts to create. Edit PDFs from your phone during a commute, sign contracts on a tablet during meetings, or modify documents on any computer with internet access. Breklo is the most accessible PDF editor available, free forever and updated regularly with new features.
