Compress PDF

Compress PDF files online by recompressing embedded images in your browser. Text-only PDFs may not get much smaller.

To compress pdf, upload your file, let your browser process it locally, and download the result in a few clicks.

Three simple steps

Compression runs in your browser. Recompressing images keeps text selectable, but a text-only PDF often stays about the same size. Redrawing pages usually shrinks scans and photo PDFs more, and the text will no longer be selectable. Encrypted PDFs are not supported.

What happens to your file?

This tool processes files locally in your browser. Confiles does not upload or store your file, and you get the result right away without creating an account.

When to use it

Use this when a PDF is hard to email, upload, or share because photos or scanned pages make the file large.

Limitations

Image recompression keeps text selectable, but text-only PDFs often do not get smaller. Redrawing pages can shrink scans more, and the text becomes part of the image. Encrypted PDFs are not supported.

Examples

  • Shrink a scanned packet before email.
  • Reduce a photo PDF for a form upload.
  • Make a report easier to share when the images are the heavy part.

Supported formats

This tool works with PDF.

FAQ

Can I use this PDF tool on my phone?

Yes, as long as your phone can open the file in the browser. The tool is designed to compress a PDF with large buttons and simple steps.

Does this keep the original PDF private?

Yes. These PDF tools run in your browser, and Confiles does not upload or store your PDF.

Do I need an account to edit a PDF?

No. Upload the PDF, wait while it processes, and download the result.

Will every PDF get smaller?

No. This tool recompresses embedded images. Text-only PDFs often stay about the same size. Scanned and photo PDFs usually shrink more.

Does compression keep the text selectable?

Recompressing images keeps text selectable. Redrawing pages turns each page into a JPEG, so the text is no longer selectable or searchable.

What if the PDF is still too large to send?

Extract the pages you were asked to send, or redraw the file if it is a scan. Image recompression cannot shrink a text-only PDF under an upload limit.
