None
Store entries without DEFLATE compression for the quickest packaging.
Private PDF tool
Package multiple PDFs into one ZIP archive while every source file stays in your browser. Keep documents separate, choose their names and order, optionally add a folder, then download the archive without changing PDF contents. This does not merge pages, password-protected files remain protected, compression may not reduce already-compressed PDFs, and large batches depend on device capacity.
Drop PDFs here
Choose two or more PDFs. Invalid and duplicate files are reported separately without discarding valid selections.
Nothing is uploaded
PdfEditorOnlineFree validates and packages the selected files in this tab. ZIP compression changes how bytes are stored inside the archive, but extraction restores the original PDF bytes. There is no upload endpoint and your source files are never overwritten.
Four packaging profiles
None, Fast, Balanced, and Max control ZIP compression effort. Balanced is the practical default. Many PDFs already compress images, fonts, and content streams, so Max can take longer without producing dramatic savings.
Store entries without DEFLATE compression for the quickest packaging.
Use light compression when packaging speed matters most.
Use a practical middle level for ordinary document batches.
Spend more CPU time seeking the smallest ZIP this browser can produce.
How to package PDFs
Choose or drop two or more PDFs. Invalid and duplicate files are named without removing valid companions.
Rename entries and set their ZIP order with drag or the explicit move controls.
Name the archive, choose compression, and optionally place everything inside one named folder.
Review the source and estimated archive sizes, package locally, then download the completed ZIP.
ZIP entries follow the visible order. Safe filename cleanup removes path traversal and duplicate entry names while retaining a separate `.pdf` file for every accepted source.
Leave files at the archive root or place them under one folder. The suggested folder name is PDFs, and you can replace it before packaging.
There is no artificial upload cap. Batches above the 150 MB desktop or 50 MB mobile smooth-use guides trigger a warning because inputs and the archive can briefly coexist in memory.
Frequently asked questions
No. Every PDF remains a separate file inside the ZIP. Use Merge PDFs when you want one document with one continuous page sequence.
Yes. Packaging does not open or alter the document, so a valid protected PDF can remain protected inside the archive.
PDFs commonly contain compressed streams already. ZIP headers add a little overhead, and DEFLATE may find little additional repetition. The exact result and savings are shown after packaging.
No PDF bytes are uploaded. After this page and its application code are available, selection, validation, compression, and download happen in the browser.
