The frustration of filing your daňové přiznání on Finanční správa portal — only to have the portal reject your PDF for exceeding the file-size limit — is familiar to many Czech Republic residents. Our free compressor eliminates that obstacle. Upload your document — a daňové přiznání tax returns or a multi-page scanned file — choose a compression level, and download a portal-ready PDF in seconds. Three levels give you full control. Works on any device across Prague, Brno, and Ostrava and all of Czech Republic, no account needed. GDPR (zákon č. 110/2019) requires processors to retain personal data only as long as strictly necessary. We go further: files are automatically and permanently deleted within 1 hour, HTTPS transport encrypts every byte in transit, and our servers never log document content. Safe for even the most sensitive Czech Republic documents.
