Files never leave your device.How it works
How to zip PDF files
- 1Add your PDF files above (or click to select).
- 2Click Create ZIP.
- 3Download the single .zip archive.
Frequently asked questions
- Does this merge the PDFs?
- No. Each PDF stays a separate file inside the ZIP — nothing is combined or re-encoded. To join them into one document, use Merge.
- Do my files get uploaded?
- No. The archive is built entirely in your browser — your files never leave your device.
- What if two files share a name?
- Duplicate names are automatically given a numeric suffix so nothing is overwritten.
One tidy archive
Emailing a handful of PDFs is easier as a single attachment. PDFs to ZIP packs your files into one .zip — no merging, no quality change, just a convenient container built right in your browser.
Everything preserved
Each PDF goes into the archive untouched, keeping its own name; duplicate names get a numeric suffix so nothing is lost. The result is a standard ZIP that opens on any system.
Notes and limits
The archive is created locally, so your files never leave your device. If you actually want the pages combined into a single document rather than separate files, use Merge instead.
What actually goes into the archive
A ZIP file is a container format, not a compression scheme applied uniformly to everything inside it — each entry can be stored as-is or compressed, and the archive builder picks per file. PDFs are usually already compressed internally, their text streams and images are typically deflate-compressed or JPEG-encoded, so zipping a folder of PDFs rarely shrinks the total size by much; the value here is bundling, not squeezing. If you actually need smaller files, shrink each PDF individually with Compress before zipping, since that operates on the PDF's internal streams rather than the outer container.
Structure of the archive
The ZIP comes out flat — every PDF sits at the top level of the archive, in the order you added them, with no subfolders created. That keeps it simple to open on any device, from a phone's built-in file browser to a desktop unzip tool, without digging through nested directories.
Common real-world uses
- Sending a set of scanned exhibits or supporting documents as one email attachment instead of many
- Archiving a year's worth of invoices or statements as a single dated file
- Handing a batch of separately-generated reports to someone who needs each one intact and individually openable
It also pairs naturally with Split: break a large PDF into its individual pages or sections first, then zip the results into one file that's easy to send, rather than attaching a dozen loose files one at a time. If what you actually want is a single combined document rather than a bundle of separate ones, Merge is the better starting point.
