Will I lose quality when I compress my PDF?

We use smart compression algorithms that target redundant data and optimize images within the PDF. You'll get a significantly smaller file with minimal to no visible loss in document quality.

How much can I reduce my PDF file size?

Most PDFs can be reduced by 40-80% of their original size, depending on how many images and high-resolution assets are inside the document.

Is it safe to compress confidential legal or business PDFs here?

Yes, it's safer than almost any other online tool. Your files are compressed entirely in your browser memory and are never sent to a cloud server, ensuring your data remains private.

Is it safe to use Edita for sensitive files?

Absolutely. Edita processes all your files locally in your browser using WASM (WebAssembly) technology. Your documents never leave your device and are never uploaded to our servers, ensuring total privacy.

Does Edita store my data or file history?

No. We have a strict 'no-storage' policy. Once you close your browser tab, all traces of your processed files are gone. We don't track your content or keep any logs of your file data.

Why is Edita faster than other online converters?

Traditional tools require you to upload large files to a server, wait for processing, and then download them back. Edita eliminates all network lag by processing everything instantly on your own hardware.
