Compress PDF for startups
Updated July 2026
Arthize lets startup founders and teams compress a PDF in a private workspace — free, with no watermark. Compressing a PDF reduces file size — often 50–90% on image-heavy scans — by down-sampling images and stripping redundant data, while keeping text selectable.
Why startups compress a PDF
A founder exports the pitch deck to PDF, merges it with financials into a data-room file, and sends a SAFE for e-signature — without paying for enterprise document software.
Built for pitch decks. Whether it's pitch decks, cap tables, contracts, Arthize's compress pdf keeps the work inside your private workspace. Fundraising materials and cap tables are highly confidential; private processing is critical.
What matters when you compress a PDF
PDF file size almost always comes from embedded images, not text.
Down-sampling scans to a lower DPI usually gets an image-heavy file under 1MB.
Light compression is visually lossless for most documents.
