Comprimir PDF
Reduce el tamaño de un PDF.
La compresión convierte las páginas en imágenes con la calidad elegida — el texto deja de ser seleccionable. Ideal para PDF escaneados o con muchas imágenes.

Preguntas frecuentes
Are my files uploaded to a server?
No. PDF processing happens locally in your browser with pdf-lib, so your files never leave your device and nothing is stored.
Why might my PDF not get smaller?
Text-based PDFs are already compact, so rasterizing them can make them larger. The tool detects this and keeps your original unchanged instead of pretending to compress.
Will text still be selectable?
No — this method flattens pages to images, so text is no longer selectable. It works best for scans and image-heavy PDFs. For other files, this is a deliberately simple first version.
Is it really free?
Yes — free, with no signup, no watermark and no limits.
