Compress PDF for small businesses
Updated July 2026
Arthize lets small business owners 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 small businesses compress a PDF
A small business merges the month's receipts into one file, converts a proposal to PDF for a client, and password-protects a sensitive contract before emailing it — on a free plan with no per-seat cost.
Built for invoices. Whether it's invoices, contracts, receipts, Arthize's compress pdf keeps the work inside your private workspace. A small business's financial and client documents are confidential and shouldn't be retained by a free ad-funded tool.
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.
