Live Web App: https://pdf.sealkit.org
Open Source Core: github.com/sealkit-org/pdfseal (GNU AGPL-3.0)

PDFSeal is a 100% client-side, zero-upload PDF manipulation suite and automation pipeline. Unlike legacy cloud converters (Smallpdf, iLovePDF) that transmit your sensitive tax documents, bank statements, and legal briefs to remote third-party servers, PDFSeal executes all operations entirely within your local browser memory space.

Zero Server Uploads: Even if you disconnect your computer from the internet (airplane mode), PDFSeal functions completely normally.
Precision Target-Size Compression: Dial in an exact target file size (e.g. 2.0 MB for US visa portals or 4.0 MB for IRCC).
True Vector Redaction: Permanently burns black redaction boxes and scrubs underlying text streams, compliant with US Federal Rule of Civil Procedure 5.2.
Metadata Sanitization: Strips hidden author tags, GPS location markers, creation timestamps, and editing histories in one click.
