When a portal asks for a PDF under 400 KB
400 KB appears on recruitment and scholarship forms for caste, income and category certificates. It usually fits two or three scanned pages, or one page photographed with a phone after cropping.
Start with Preserve text, which keeps text selectable and only removes waste inside the file. If the result is still above 400 KB, use Scan-style, which redraws each page as a picture at the quality that fits. Zoom into the preview before you download: stamps, signatures and small print must still be readable.
One published example is the SC/ST certificate for the free travel pass on RRB applications (PDF under 400 KB). Other limits: 300 KB, 500 KB, 1 MB.

Check the requirements on your form
PDF editing can invalidate digital signatures and may affect interactive fields, links or annotations. For signed or official originals, use a copy and inspect the output.
Will my file be uploaded?
No. Processing happens in your browser, including PDF rendering, scanning and ZIP creation. Tool code is downloaded from this website; the documents you select are not sent back.
Can every file reach the requested size?
No. A size limit is a maximum, not an exact guarantee. Detailed or multi-page documents may need a larger limit to remain readable. One KB here is 1,000 bytes. Check clarity and any minimum file size before submission.
My certificate is 2 MB. Can it reach 400 KB?
Usually yes with Scan-style compression, especially after removing blank pages and cropping each page to the paper edge.
Will the text still be readable?
Check the preview at full zoom before downloading. If small print is blurred, choose a higher quality or keep only the pages you need.
Is my file uploaded?
No. The PDF stays on your device.
