500KB upload-limit preset
The compression controls are tuned for users trying to get a PDF below 500KB. Exact output depends on the original PDF, especially scanned image-heavy documents.
Private in-browser compression
Your PDF is processed locally in your browser. The file is not uploaded to UtilNest or stored on a server.
Check before submitting
After downloading, check the final file size. Very large scans may need another pass or image optimization before they can fit under 500KB.

Frequently asked questions
Can this guarantee a PDF below 500KB?
No browser compressor can guarantee every PDF will fit below 500KB. Text-heavy PDFs usually compress well; large scanned PDFs may remain bigger and need source image resizing.
Is my PDF uploaded?
No. Compression runs locally in your browser.
Will the layout change?
The tool preserves page dimensions and pagination, but strong compression can reduce image sharpness.
What should I do if it is still too large?
Try stronger compression again, reduce scanned image resolution before making the PDF, or split unnecessary pages.
