SoHappyPDF is a tool-first PDF product. You open one page, drop a file, download the result, and leave. Basic use does not need an account. Files stay private to your session and expire after about two hours — that is the product, not a missing feature. There is no document library to manage and no desktop app to install. The whole product is three steps: open a tool, drop a file, download when it is done. 37 tools are live today. Organize: merge, split, extract, reorder, remove pages, rotate, crop. Optimize: compress, repair, PDF/A. Convert in both directions: Word, Excel, PowerPoint, JPG, PNG, TXT. Edit and secure: watermark, page numbers, protect, unlock, sign, redact. Pro adds OCR and higher limits. It is built for freelancers and small teams who already have a job to finish — contracts, invoices, HR paperwork, client deliverables. Visit, finish, leave. Signed-in accounts get recent activity, billing, and API keys. Developers can run the same pipeline through a public API: upload, convert, poll, download. Free: 5 operations per day, 25 MB files, 50 pages. Pro is $5/month: unlimited daily operations, files up to 1 GB, OCR, and premium tools. All accounts include a small API allowance; extra API packs start at $9/month. PDF tools are often cold and crowded. SoHappyPDF is the other kind: round, a little yellow, and focused on finishing the job. PDF tools, one happy place. https://sohappypdf.com
