When to use Compress PDF to 500 KB

• University applications. Transcripts, degree certificates and recommendation letters for Indian and overseas universities.
• Visa applications. Bank statements, sponsorship letters and itineraries.
• Job applications. Resumes with photos and portfolio PDFs.

What fits in 500KB

At 500KB you can usually keep colour: a 5 to 10 page scanned document in colour at moderate quality, or dozens of pages of a digital PDF. Seals, signatures and photos stay recognisable, which matters for verification.

If the PDF will not go under 500 KB

• Split it: use Split PDF to upload the pages as separate files, or remove pages the form does not need.
• Rescan at a lower resolution: 150 DPI in grayscale is enough for most text documents.
• Photograph each page and use JPG to PDF with a maximum PDF size, which handles phone photos well.
• Use grayscale: colour scans of black-and-white pages are often three times larger than they need to be.

Limits and privacy

• First the tool recompresses the images inside the PDF and keeps the text selectable. Only if that is not enough does it turn pages into images (you can switch this off).
• Target: university and visa applications that commonly allow up to 500KB per document.
• One PDF at a time, up to 200MB. Password-protected PDFs need to be unlocked first.
• PDFs are processed in your browser with pdf-lib and pdf.js, which are served from this site. Your file is not sent to a server, and nothing is kept after you close the page.
