Frequently asked questions
Can every PDF be compressed to 300 KB?
No. A long or image-heavy PDF may need more space to stay readable.
How do I compress a PDF toward 300 KB?
Choose your PDF and press Process PDFs. The 300 KB target is already selected.
What affects the compressed PDF size?
Image resolution, colour, fonts, page count, and existing compression affect the result.
Will compression reduce image quality?
It can. Check the downloaded PDF before submitting it.
Will my file be stored?
No. Compression processes it in memory and returns the result directly.
