Get the right PDF compression result

Light: best quality

Best for portfolios, official publications, and print documents. Keeps images sharp and cleans up document structure without noticeable quality loss.

Balanced (recommended)

The ideal default for reports, forms, and everyday documents. Balances clear text and visuals with substantial file size savings.

Extreme: smallest size

Achieves the smallest possible file size with heavy image compression. Ideal for strict email attachment caps and online form uploads.

Turn on the searchable text layer option if your PDF has scanned pages so text can be copied and searched.

How to compress PDF files

  1. Choose your PDFs

    Select up to 10 PDF files up to 100 MB each, or drag and drop them straight into the browser.

  2. Set level & options

    Choose your compression level, unlock password-protected files, or add a custom text watermark.

  3. Compress and download

    Select Compress PDFs, then save individual files or download all results in one ZIP archive.

When should you compress PDFs?

Compressing PDFs helps when email services reject large attachments, application portals enforce strict upload limits, or you want to save storage space on your device.

Text and vector diagrams stay sharp, while high-resolution photos and scanned pages are optimized for convenient sharing without sacrificing readability.

Private local processing

All compression, password unlocking, text layer addition, and watermarking happen directly on your device. Your PDF files are never uploaded or sent to any server.

Because processing runs locally in your browser, files are handled sequentially to keep your device smooth and responsive throughout the batch.

FAQ

No. Compression runs entirely in your browser. Your PDF never leaves your device, which is also why large files can take a minute on slower machines.
Balanced is a great default for typical documents. Pick Light when you need near-original quality, or Extreme for the smallest possible file, such as when emailing a scan.
Standard PDF files up to 100 MB each are supported, with up to 10 files per batch. For a password-protected PDF, enter its current password to create an unlocked compressed copy.
Yes. Add up to 10 PDFs and the tool processes them one at a time to keep the browser responsive. Download each result or get every successful result in one ZIP file.
Yes, when you know the current password. Enter it before processing and the downloaded copy will be unlocked. The tool does not guess or bypass unknown passwords.
Yes. Add custom text to every page and choose its position, size, color and opacity. Watermarking works together with compression, password removal and optional searchable text.
Scanned PDFs are pictures of pages, so their text cannot be searched or copied. This option recognizes English and Indonesian text on scanned pages and adds an invisible text layer, while leaving pages that already contain text untouched.
Some PDFs are already tightly compressed. When that happens the tool reports it clearly, and you can still download the processed copy if needed.
PDF compression runs in current versions of Chrome, Edge, Firefox, Safari and other modern browsers.
