Why Compress PDF Files?
Smaller PDFs are easier to attach to email, upload to forms, store and share. Results depend on the document: image-heavy PDFs may shrink substantially, while text-only or already optimized files may change very little.
Private PDF Compression
Processing happens inside your browser. WCODX does not upload or store the selected document.
PDF Compression Quality
This browser-based tool rebuilds each page as an image, so interactive form fields, selectable text, links and vector elements may not be preserved. Use the Maximum quality option when visual fidelity matters.
Frequently Asked Questions
Is this PDF compressor free?
Yes. The tool is free to use in your browser.
Are my PDF files uploaded to WCODX?
No. The selected PDF remains in your browser during processing.
Will compression reduce PDF quality?
It can. Recommended and Strong use more JPEG compression; Maximum quality preserves more visual detail.
Why did my PDF not become much smaller?
Some PDFs are already optimized or contain mostly text. The tool reports the actual result and never claims savings when the generated file is larger.
Can I compress PDF files on mobile?
Yes, if the mobile browser has enough available memory for the document.
What is the maximum PDF size?
The current browser-side limit is 50 MB.
