Question 1

Is 300KB enough for a clear scanned document?

Accepted Answer

Yes, 300KB is usually more than enough to keep scanned text, stamp seals, signature markings, and layout lines sharp and highly readable.

Question 2

Will the visual layout of my pages change when resizing to 300KB?

Accepted Answer

No, our compressor preserves vector paths, layout coordinates, and font tables. The original layout and alignment remain untouched; only heavy image resources are optimized to hit 300KB.

Question 3

Can I compress multiple PDFs to under 300KB at the same time?

Accepted Answer

Absolutely! Batch processing is fully supported. You can drop multiple files and they will compress to 300KB or less in parallel directly in your browser.

Question 4

Is this PDF compressor free and does it require signup?

Accepted Answer

Yes, completely free, no signup, no daily limit, and no watermarks added to your files.

Question 5

Is my PDF uploaded to a server?

Accepted Answer

No - everything happens locally in your browser via client-side processing, so your personal files are never uploaded or shared.
