Batch Compress PDF

Compress many PDFs with the same local settings. Each file runs independently, so one corrupted or password-protected PDF does not stop the rest of the batch.

Options

Low, balanced, high, or custom image compression settings.

Optional shared password for encrypted PDFs with the same open password.

Metadata removal, form flattening, and page-image compression controls.

Individual downloads plus ZIP download for successful outputs.

  4. Download — Download individual PDFs or all successful outputs as a ZIP.

FAQ

Does one bad PDF stop the whole batch?
No. Failed files are shown inline and the rest keep processing.
Are my PDFs uploaded?
No. Compression and ZIP creation happen in your browser.
Can different files use different passwords?
Not in this batch tool. Use the single Compress PDF tool for files that need different passwords.
