Compress PDF Online Free — Best Tool for Spain Users
Compress PDF online free — trusted by Spanish users. Works for AEAT, Seguridad Social, and Spanish eAdministration. Meet upload limits for Modelo 303, DNI copies, and IRPF declarations. No signup, no watermark.
AEAT, Seguridad Social, and Spanish eAdministration and other Spain government platforms enforce file-size limits of 1–5 MB per document. A rejected upload means resubmission delays — a real problem when handling time-sensitive Modelo 303, DNI copies, and IRPF declarations. Our free PDF compressor solves this without any software installation. Upload your document, choose a compression level, download a portal-ready file. Medium compression works for most Spain document types; high compression tackles image-heavy scans. No watermark, no account, no cost. Once processing completes, an automated deletion timer starts. Your file is permanently removed within 1 hour — not archived, not analysed, not shared. All traffic uses HTTPS encryption. This workflow is designed to meet the data-minimisation expectations of GDPR (LOPDGDD) for Spain residents sharing sensitive official documents.
