How do I compress a PDF file for free?

Go to editpdf.co.in/tools/pdf-compress, upload your PDF, choose a compression level (Maximum, Balanced, or High Quality), and click 'Compress PDF'. The compressed file downloads instantly with no sign-up required.

How much can I reduce a PDF file size?

Compression results depend on the PDF content. Image-heavy PDFs can often be reduced by 50–80%. Text-only PDFs have less room for compression. The tool shows you the original vs compressed size after processing.

Can I compress a PDF to a specific size like 100KB or 200KB?

Yes. Use the Advanced Settings in the compressor to adjust JPEG quality and maximum image dimension. Lower quality and smaller dimensions result in smaller file sizes. Experiment with these settings to target sizes like 100KB, 200KB, or 500KB.

Will compressing a PDF affect the text quality?

No. Text in PDFs is stored as vector data and is not affected by compression. Only embedded images are compressed. Choose 'High Quality' mode to minimize any visible image quality reduction.

Advanced Client-Side PDF Compression

Our PDF Compressor online allows you to reduce PDF file size by up to 80% with no quality loss. The key mechanism runs entirely in-browser using advanced client-side libraries. By converting, scaling, and adjusting maximum resolutions of embedded images locally, none of your private documents are sent to external systems.

Customize your file compression presets:

Maximum Compression: Best for strict portal uploads targeting small files (approx. ~70% smaller) with slight image downscaling.
Balanced Compression: The default mode that offers a smart balance between image quality and significant size savings (~50% smaller).
High Quality Mode: Minimal image quality reduction with a light size optimization (~30% smaller).

Adjust advanced sliders like max pixel dimensions or grayscale mode to target specific file sizes (100KB, 200KB, 500KB) with precision.
