Pack PDF Files Into a ZIP

Collect several PDF documents into one ZIP archive so you can send them as a single attachment.

Pack PDF Files Into a ZIP Archive Online

Sending fifteen separate PDFs is a nuisance for everyone. Mail clients limit the number of attachments, upload forms often accept only one file, and the recipient has to save each document individually into the right folder. A ZIP archive turns the whole set into a single attachment that arrives complete, in order, with the original file names intact.

Select the documents you want to include, add or remove files until the list is right, and build the archive. Everything happens inside your browser: the PDFs are collected into a ZIP on your own device and never uploaded anywhere, which makes this a safe way to bundle contracts, medical records, invoices and other confidential paperwork. The archive downloads immediately, and it opens with the built-in extractor on Windows and macOS as well as with any archiving program.

One point worth being clear about: a ZIP groups files together, it does not meaningfully shrink them. PDFs are already compressed internally, so the archive will be roughly the size of its contents. If your goal is a smaller total size rather than a single attachment, compress the documents individually with the Compress PDF tool first, or merge them into one file with Merge PDF. The service is free and unlimited.

Frequently Asked Questions

How do I put several PDFs into one ZIP file?

Choose the documents you want on this page, adjust the list if needed and press the button to create the archive. The ZIP is ready to download immediately.

Will the archive make my files smaller?

Not by much. PDFs are already compressed, so a ZIP mainly groups them together. To reduce the size, compress each PDF first with the Compress PDF tool.

Are my documents uploaded to a server?

No. The archive is assembled in your browser on your own device, so the files never leave your computer — which matters for confidential paperwork.

How does the recipient open the archive?

Windows and macOS both open ZIP files natively with a double click, and every archiving program supports the format on Android, iOS and Linux too.

Should I use a ZIP or merge the PDFs instead?

Use a ZIP when the documents must stay separate files with their own names. Use Merge PDF when a single continuous document would be more convenient to read.

Is there a limit on the number of files?

There is no limit on how many PDFs you add, and each file can be up to 100 MB. The tool is free and adds nothing to your documents.
