PerPageFax is a pay-per-use online fax service that lets you send a fax from any browser without creating an account or committing to a subscription. Upload a PDF or image (PNG, JPG, HEIC, TIFF), enter the recipient's fax number, and pay only for what you send — a flat $0.50 per page through secure Stripe checkout. Documents up to 100 pages and 20 MB are supported, and multiple files are merged into a single fax automatically.
