Frequently asked questions

Will a scanned PDF fit into 900 KB?

It depends mostly on the page count. Every scanned page is stored as an image, so long scans grow fast. Choose Medium or High and check the estimate. If a long scan is still over 900 KB, rescanning at a lower resolution, such as 150 DPI, or removing pages you don't need will help.

Will the text stay easy to read?

Yes, in most cases. 900 KB leaves plenty of room for text, which takes up very little space and usually stays sharp at every level. Images are what compression reduces the most. If you have to use High, zoom in on small print before you send the file.

Do many small pictures pass 900 KB sooner than one large picture?

Not necessarily. What matters is the total image data, not the number of pictures. Ten small images can take less space than one large, high-resolution photo, or more if each one is detailed. Check the estimate at Medium or High to see where your file lands.

Can compression make a PDF lose quality?

It can, mostly in images. High gives the smallest file but may soften photos, while Low keeps the highest quality. Because 900 KB is a fairly roomy target, many documents reach it at Low or Medium, so you can often compress PDF to 900 KB without losing quality you would notice.
