Browser-fixed tools
Merge, compress/optimize, split range, extract pages, remove pages, rotate, image to PDF, PDF to image and text extraction have browser fallbacks for normal files.
PDFio System Check
Use this page after deployment to verify whether the VPS has the PDF engines needed for advanced PDF processing. Browser mode handles several tools automatically, but OCR, Office conversion, strong compression and password tools need server packages.
One-command VPS install
Run this on Ubuntu VPS, not in Hostinger file manager/shared hosting:
sudo apt update sudo apt install -y qpdf ghostscript poppler-utils tesseract-ocr tesseract-ocr-hin php-zip img2pdf python3-pil zip libreoffice # Restart PHP/Apache service depending on your stack: sudo systemctl restart php8.4-fpm 2>/dev/null || sudo systemctl restart php8.3-fpm 2>/dev/null || sudo systemctl restart php8.2-fpm 2>/dev/null || sudo systemctl restart php8.1-fpm 2>/dev/null || sudo systemctl restart apache2 2>/dev/null || true sudo systemctl reload nginx 2>/dev/null || true
Server-only tools
OCR, searchable PDF, password protect/unlock, repair, heavy compression and Office conversion need VPS packages.
Hosting note
If this site is on Hostinger shared hosting, you normally cannot install apt packages. For a competitor-grade PDF site, deploy on VPS.
Force compression readiness
Status: not ready
Force smaller/rasterize needs one renderer plus one PDF builder. Renderer available: no. Builder available: no.
If it is not ready after installation, restart PHP-FPM/Nginx and reload this page.
