Where you meet a 500KB limit
Admission portals, bank and NBFC KYC uploads, loan and insurance claim forms and job portals often allow up to 500KB per document. It is also a reasonable size to send on WhatsApp or by email.
Keeping the text sharp
500KB is a fairly generous limit, so GreenPDFs can usually get there with lossless optimisation. The pages are not turned into images, which means the text stays selectable and prints cleanly. A large colour scan may still need converting to high-resolution images, and you will see a preview either way.
Multi-page documents
As a rough guide, 500KB holds about 5 to 10 scanned pages in grey-scale, or many more pages of a typed PDF. For six months of bank statements, remove the passwords, merge the months and compress the combined file here.
Why your file stays private
Compress PDF to 500KB runs entirely inside your browser. Your file is read from your device, processed in memory and saved back to your device. It is never uploaded to GreenPDFs or anyone else, so you can use it with Aadhaar, marksheets, bank statements and other personal documents. How in-browser processing works.
Frequently asked questions
Can every PDF be compressed to 500KB?
Most can. Typed PDFs and light scans get there easily. A long scan full of photos sometimes can't, and in that case the tool shows the smallest size it reached and suggests what to try next, such as removing pages, cropping margins or splitting the file.
Will the text still be readable?
The tool first tries a lossless optimisation, which keeps text sharp and selectable. If that isn't enough, it saves the pages as images at the highest resolution that still fits 500KB, then shows you a preview to check before you upload.
Does it work on a mobile phone?
Yes. Open this page in Chrome or Safari on Android or iPhone, pick the PDF from Files or Downloads, and download the result. There is nothing to install.
Is my document uploaded anywhere?
No. GreenPDFs works inside your browser, so the PDF stays on your phone or computer. You can use it for Aadhaar, marksheets and other personal documents.
How many pages fit in 500KB?
Typed PDFs often fit 50 pages or more. Scanned pages fit roughly 5 to 10 in grey-scale. The tool shows the final size before you download.
