Comprimir PDF sin perder calidad

We use Ghostscript's "ebook" optimisation profile, which resamples images to 150 dpi and removes redundant metadata. Text and vector graphics are never degraded — only raster images are resampled.

Yes. Compression only affects image data. Text, links, bookmarks, and the document structure remain fully intact and selectable.

If you plan to print the PDF at A3 size or larger, you may notice image softness. For all digital uses — screens, email, web — the quality is indistinguishable from the original.

Lossless PDF compression (removing only redundant internal data without touching images) typically yields only 5–15% savings. For most users, the "ebook" profile gives the best balance of size reduction and visual quality.
