DocFixer is 100% free and works without an account. Just go to any tool page and upload your file – that’s it. If you choose to create an account (optional), you can access your history and save preferences.
Click the “Select files” button or drag & drop directly into the upload area. You can upload PDFs, Word documents, Excel sheets, images (JPG, PNG), and more. Maximum file size: 2GB (no hidden limits).
Each tool has a simple interface: after upload, you’ll see options like merge order, page ranges, compression level, etc. Adjust them, then click “Process”.
Your file is processed in seconds (usually under 10s). Download it directly – we delete all files from our servers after one hour for your privacy.
Every tool follows the same 3‑step pattern:
For example, in Merge PDF, you can reorder files by dragging. In Compress PDF, you choose compression level (low, medium, high). The interface is always clean and self‑explanatory.
Upload up to 20 PDF files. After upload, you'll see thumbnail previews. Drag to reorder, check "include all pages", then click Merge. The combined PDF downloads in seconds.
Tip: You can also mix images (JPG) – they will be converted to PDF automatically.
Two modes:
• Split by pages: enter page ranges (e.g. 1-3, 4-6)
• Extract single pages: click on thumbnails to select. After splitting, you get a ZIP file with separate PDFs.
Choose compression level: Low (minimal size), Medium (balanced), High (best quality, larger file). We reduce images and remove duplicate data. Usually shrinks files by 30–60%.
Protect: add text or logo watermarks to protect your pdf and claim copywrights. Adjust position, opacity, and size easily.
Generate custom QR codes from any URL or text. Pick colours & download instantly.
Each page becomes a JPG image. You can download all as ZIP. Quality setting: choose 72dpi (web) or 300dpi (print).
Upload multiple JPG/PNG, reorder them, choose page size (A4, Letter, etc.) and orientation. Outputs a single PDF.
Your privacy is our top priority. All file processing happens directly on your device — nothing is uploaded to anyserver. We never look at your content, and we don't sell data. You remain anonymous – no sign‑up needed.
We do not store, track, or access your files at any time. Everything runs securely in your browser, ensuring complete control over your data.
