Frequently asked questions
Can a scanned page really fit in 50 KB?
Usually one page can, if it is cropped to the paper and photographed in good light. Shadows and background clutter use up the space, so a clean, flat photo of the page makes the biggest difference.
My PDF has several pages. What can I do?
Upload only the pages the form needs: keep just those with Extract PDF Pages, then compress the smaller file here. Every page you remove frees space for the others.
Will the text still be selectable?
Only if the PDF fits after lossless optimisation, which the tool tries first. Scans become images, so their text cannot be selected, but forms that ask for a scan do not need that.
Is my PDF uploaded when I compress it to 50 KB?
No. Your PDF is compressed inside your browser and never sent anywhere, which matters for documents such as certificates and ID proofs.
What fits in a 50 KB PDF
50 KB is a very tight limit for a PDF, usually set for a single document such as a signature sheet, ID page or certificate on an application form. A PDF made from Word or Google Docs often fits as it is; a phone scan has to become a low-resolution image to fit.
As a rough guide from our tests with phone photos of documents, expect room for about one scanned page, at a resolution where normal-size text is just readable. Clean scanner output fits more, and PDFs made from Word or Google Docs are often small enough already.
