Compress a PDF for a sede electrónica upload
Fit the size limit of a Spanish e-government portal, without uploading your file.
Spain’s sedes electrónicas, from the Agencia Tributaria and Seguridad Social to the DGT and your ayuntamiento, cap the size of each document you upload, and a normal scan is usually too big. This tool compresses your PDF to your target size on your device, so a document with your personal details is never uploaded to a third party.
