Comprimir PDF
Reduza o tamanho de um PDF.
A compressão converte as páginas em imagens na qualidade escolhida — o texto deixa de ser selecionável. Ideal para PDFs digitalizados ou com muitas imagens.

Perguntas frequentes
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.
