New in Compacto: merge, split, export, password-protect and more. Nine additional PDF tools. No subscription. 100% offline. No file ever leaves your Mac. Compacto is a Mac app for shrinking, splitting and sorting PDFs. Works offline. No account, no upload, no fuss. Drop a PDF in, pick a size, get it back smaller — all on your Mac. You've been there. The PDF is too big to email. The upload sites want you to sign up. The desktop apps want more than you do. You just want the file smaller. Compacto skips all of that. Drop it in, pick a size, done in seconds. The file never leaves your Mac. PDF COMPRESSION — INCLUDED - Drag. Drop. Done. - Three compression levels: Smallest for email, Balanced for most things, Best when quality matters. - Preview the result before you save. - Batch compress a whole folder in one pass. - Right-click any PDF in Finder and choose Crush It — no need to open the app. THE FULL TOOLKIT Nine more tools, for when you do more than compress. CONVERT - Export any PDF page as JPEG or PNG at 72, 150 or 300 DPI. - Collect a folder of images into a single PDF. Pick layout and captions. - Convert any document to greyscale. ORGANISE - Merge multiple PDFs. Drag to reorder. - Split by page range. - Trim pages you don't need. - Rotate 90°, 180° or 270°. SECURE - Password-protect a PDF before you send it. - Remove a password from a PDF you own. EVERYTHING WORKS OFFLINE - No account. - No file size limit. - No watermark. - No internet connection needed. compacto.app
