How It Works

Browser-Based Processing

Unlike tools that upload your files to a remote server, Pixellwork Tools uses client-side processing. Your PDFs and images never leave your computer — your browser does all the work using modern JavaScript libraries loaded directly onto the page. This means complete privacy, faster results, and no file-size limits imposed by server infrastructure.

PDF Organize Tools

• Merge PDF — Uses pdf-lib to read each uploaded PDF, copy all pages into a new document, and produce a single combined file.
• Split PDF — Reads a PDF with pdf-lib and writes each page (or custom page range) into its own separate PDF file.
• Remove Pages — Loads your PDF, skips the page numbers you specify, and saves the remaining pages as a new document.
• Extract Pages — Keeps only the pages you specify and discards the rest.
• Organize PDF — Renders thumbnail previews using pdfjs-dist so you can drag pages into a new order, then rebuilds the PDF with pdf-lib.
• Scan to PDF — Wraps uploaded images (photos, scans) into a PDF using jsPDF, fitting each image to its own page.

PDF Optimize Tools

• Compress PDF — Re-saves the PDF with pdf-lib using object stream compression (useObjectStreams: true), which reduces the file size by removing redundant data structures.
• Repair PDF — Re-parses the PDF with pdf-lib using lenient parsing (ignoreEncryption: true) and re-serializes it, fixing many common structural errors and corruption issues.
• OCR PDF — Uses pdfjs-dist to extract embedded text from each page of a scanned or text-based PDF and saves the result as a plain .txt file you can search and copy from.

PDF Convert Tools

• PDF to JPG — Renders each PDF page to a canvas at 2× resolution using pdfjs-dist, then exports each canvas as a high-quality JPG image.
• PDF to Word — Extracts the text content from each page using pdfjs-dist and formats it into an HTML-based .doc file that Microsoft Word and LibreOffice can open and edit.
• PDF to Excel — Extracts text from PDF pages and organizes it into a CSV file with a UTF-8 BOM, which Excel opens correctly in any locale.
• PDF to PowerPoint — Renders each PDF page as an image using pdfjs-dist, then packages those images into a valid PPTX file (following the OOXML specification) using JSZip. The result opens directly in Microsoft PowerPoint.
• PDF to PDF/A — Re-saves the PDF using pdf-lib with PDF/A-compatible settings (metadata, no object streams), producing a file suitable for long-term archiving.

Image Tools

• Image to PDF — Converts one or more uploaded images into a single PDF document using jsPDF, preserving each image on its own page.
• PNG to JPG — Uses the HTML5 Canvas API to draw the PNG image and export it as a compressed JPG, reducing file size while maintaining visual quality.
• JPG to PNG — Uses the HTML5 Canvas API to redraw the JPG and export it as a lossless PNG, preserving all pixel detail and supporting transparency.

Key Benefits

• 100% Private: No files are stored, transmitted, or seen by us or any server.
• Fast: No upload or download waiting times — processing starts immediately.
• Free: All tools are free to use, supported by advertising.
• Works Offline: Once the page loads, most tools work without an active internet connection.
