Will compressing my PDF make the text fuzzy or hard to read?

No. The default setting keeps text and vector graphics untouched and only recompresses images, so words stay crisp and selectable. Fuzziness only appears at the most aggressive compression level, which you choose to enable.

Why is my PDF file so large in the first place?

Usually high-resolution images or embedded scans contribute most to file size. PlumeDocs Compress PDF targets these image files for re-encoding, which can significantly shrink the document without affecting text.

Does the compression happen on my computer or on a server?

All compression happens in your browser. Your document never leaves your device and is not uploaded to any server, so it remains private.

Can I compress PDFs that contain HEIC or WebP images?

Yes. The tool supports JPG, PNG, WebP, and HEIC files embedded in the PDF, re-encoding them as part of the compression process.

About this tool

What Compress PDF does

PlumeDocs Compress PDF reduces PDF file size by re-encoding only the images within the document, keeping text selectable and the layout intact. Users upload a PDF, choose a compression level, and download a lighter version suitable for email or storage. The result preserves text sharpness at default settings, while stronger modes trade some image quality for smaller files. All processing happens in the browser, so the document never leaves the user's device. The site provides real-time size estimates as the user adjusts settings, and supports common image formats like JPG, PNG, WebP, and HEIC embedded in the PDF. It requires no sign-up and is free to use.
