Email attachments, portal uploads and mobile sharing all hit the same wall: PDF too large. Tentaco compresses PDFs locally in your browser so contracts and internal docs do not pass through iLovePDF or Adobe servers.
Pick a quality preset, preview the result and download. Standard compression runs on-device with WebAssembly helpers where needed. No account, no daily limits on basic use.
Cloud PDF compressors store uploads on shared infrastructure — acceptable for public brochures, risky for HR, legal and client files under GDPR. Tentaco keeps bytes in memory on your machine for typical compress workflows.
Chain compress with merge or split in PDF Studio when you need a smaller packet for email. Bookmark for repeat one-off jobs instead of opening a desktop suite.
