Compress PDF tries to shrink one or more PDFs by rewriting their internal structure, showing the real result per file.
Cómo usarla
- Upload one or more PDFs.
- Check original size, final size, and the delta per file.
- Optional: edit the output file name.
- Download the result: a PDF if there's one, or a ZIP for several.
Casos de uso
- Trim a PDF to attach it to an email.
- Prep a document for sites with upload size limits.
- Optimize PDFs generated by other tools.
Límites
- Each file is up to 50 MB and the batch up to 100 MB total.
- The reduction depends on the content: an already-optimized PDF or one full of images may shrink little or not at all. In that case we keep the original.
Privacidad
Optimization is attempted in your browser. It doesn't recompress images or guarantee shrinkage; the result depends on the PDF's structure.
Errores comunes
- An encrypted PDF can't be compressed from this tool.
- Some PDFs with unusual structures may not be compatible.
Notas técnicas
- Uses pdf-lib to optimize the file structure; it doesn't recompress images.
- That's why the reduction is honest and, for already-light documents, can be minimal.
