Frequently asked questions

Is fitting a color scan of about 15 pages into 3 MB realistic?

It can be, but it is tight. Fifteen color pages at a typical scan resolution often come out well above 3 MB, and Medium or High can bring them much closer. Check the estimate first. If it is still over, compress the result again, or rescan in grayscale or at around 150 DPI.

Will the text stay easy to read?

Yes, in most cases. 3 MB 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, so if your file reaches 3 MB at Low or Medium, you can compress PDF to 3 MB without losing quality you would notice.

Can I reduce a PDF to 3 MB on a phone or tablet?

Yes. Open PDFFly in your phone or tablet browser, select the PDF, pick a level by its estimated size, and download the result. You can save or share it straight from your device, and compress PDF to 3 MB free of charge with nothing to install.

What if my PDF is just over 3 MB?

Then light compression is usually enough. Start with Low, which keeps the highest quality, and check the estimated size. If it is still over 3 MB, choose Medium instead. A small reduction like this rarely causes visible changes to the document.
