Merge PDF — Frequently asked questions
Are my files uploaded anywhere?
No. PDF Organizer processes every file directly in your browser, so you can merge PDF without uploading or split a document with nothing ever sent to a server. Your files never leave your device.
Is it really free?
Yes, it is completely free with no account, no trial and no hidden limits. You can compress PDF online free, merge, rotate and export as many files as you like.
How do I compress a PDF without uploading it?
Open the app, drop in your PDF and choose Compress — lossless to strip unused data, or strong mode to rasterize image-heavy pages. The whole process runs in your browser, so you compress PDF online free with nothing uploaded.
Why does text extraction return nothing for scans?
Text extraction only reads selectable text that already exists in the PDF. Scanned or image-only pages have no text layer, and PDF Organizer does not perform OCR, so those pages return nothing.
Does it work offline?
Yes. Once the page has loaded, all processing happens locally, so you can split, merge and compress PDF files even with no internet connection.
Are there file-size limits?
There are no server-imposed limits because nothing is uploaded. The only practical ceiling is your device’s memory — very large or high-resolution PDFs use more RAM while you work on them.
