Is this PDF compressor free?

Yes, 100% free with no usage limits, no watermarks, and no signup required.

How much can I reduce a PDF file size?

Depending on content, you can reduce PDF size by 20–80%. PDFs with many images compress the most. The Screen preset gives the smallest output; Print gives the highest quality.

Is there a page limit for PDF compression?

No page limit. Compress PDFs of any size or page count. Files up to 50 MB are supported.

Compression Presets Explained

EazyStudio uses Ghostscript's built-in PDF presets — the same engine used by Adobe Distiller — to optimise your PDF. Here's what each level does:

Preset	Resolution	Best For	Typical Reduction
Screen	72 dpi	Email attachments, web sharing	60–80%
Ebook	150 dpi	General use, digital reading	40–60%
Print	300 dpi	Printing, archiving	10–30%

Why is my compressed file larger?

If your PDF contains only text (no images), or was already heavily optimised, the compressed version may be similar in size or slightly larger. This is normal — Ghostscript re-encodes all streams for maximum compatibility, and text-only PDFs have little room for further compression.

Frequently Asked Questions

Is my PDF safe to upload?

Yes. Files are uploaded over HTTPS, processed in an isolated temporary directory, and deleted immediately after your download link is generated. We never read, store, or share your documents.

What's the maximum file size?

Up to 50 MB per file. For larger files, upgrade to Pro or use the desktop version of Ghostscript.

Will compression affect text quality?

No — text in PDFs is stored as vector data and is never downsampled. Only embedded images and duplicate fonts are compressed. Text will remain crisp at any zoom level.

Can I compress a password-protected PDF?

Not directly. You'll need to remove the password first (you can use a PDF unlock tool), then compress the unlocked file.

How many PDFs can I compress per day?

Guest users can compress up to 3 PDFs per day. Free account holders get 10 per day. Pro users get unlimited compressions — see plans.

Does compression work on scanned PDFs?

Yes — scanned PDFs are often the best candidates for compression since they contain large embedded images. The Screen or Ebook preset will typically reduce them by 50–80%.
