Simple online processing
You can compress PDF to 250 KB online free of charge, and most files are ready in under 30 seconds.
No installation needed

Frequently asked questions
Will the text stay easy to read?
Yes, in most cases. Text takes up very little space and usually stays sharp at every level, while images are what compression reduces the most. If you have to use High to reach 250 KB, zoom in on small or faint text before you send the file.
Can I compress a PDF on my phone or tablet?
Yes. Open PDFFly in your phone or tablet browser, upload your PDF, choose a level, and download the compressed version when it is ready. There is nothing to install or pay for, so you can compress PDF to 250 KB free of charge from any device.
Will photos push the file over 250 KB?
They can. Photos hold far more data than text, so a few large ones can easily push a PDF over 250 KB at Low or Medium. Choose High, which gives the smallest result, and check the estimate. If photos still keep the file over, remove the ones the document doesn't need.
What happens to image quality when two scanned pages must fit within 250 KB?
Each page gets roughly half the space, so the images are compressed harder than a single scan would be. At Medium or High, expect some loss of fine detail, while printed text usually stays readable. Scanning at a lower resolution, such as 150 DPI, leaves more room for each page.
