How to batch compress PDFs online
- Click the dropzone (or drag files onto it) and choose two or more PDFs from your device.
- Pick a quality preset — Smaller for the smallest file size, Balanced for everyday use, or Best quality to keep images closest to the original.
- Click Compress all. Each file is processed one at a time, right in your browser — watch the progress next to each file.
- Download files individually, or click Download all (ZIP) to get every compressed PDF in one archive.
Why batch compress with VitePDF
- Compress dozens of PDFs without uploading a single one — everything happens on your own device.
- Uses the exact same recompression as our single-file Compress PDF tool, just applied across many files in one pass instead of one at a time.
- No account, no per-file limit on how many you process — only a per-file size cap (140 MB free).
Frequently asked questions
How many files can I compress at once?
There's no fixed limit on the number of files — each one just needs to be under the free size cap (140 MB per file; Premium removes that limit). Files are processed one at a time in your browser, so a larger batch just takes a bit longer.
Do I get one file back, or several?
Each PDF is compressed separately and stays a separate file — you're not merging them. Download them one by one, or click Download All to get every compressed file in a single ZIP.
Is this the same compression as the single-file Compress PDF tool?
Yes — identical algorithm. It recompresses the JPEG images embedded in each PDF; text and vector graphics are left untouched and stay fully searchable. This page just applies it to many files in one pass instead of one at a time.
Is there a file size limit?
Files up to 140 MB each are free — Premium removes that limit entirely.
