Frequently Asked Questions
Can every PDF reach a strict 100 KB target?
If a PDF has 50 pages of scanned full-color photos, reducing it below 100 KB is physically impossible without deleting pages. Our tool applies the maximum safe compression and reports the exact achieved size.
Are my documents saved or inspected on the server?
Never. Compression runs in volatile memory streams and objects are discarded immediately upon response delivery.
Which preset is recommended for government portal uploads?
Most passport and visa portals require documents under 200 KB or 500 KB. Select the corresponding preset to match your application requirements.
Does compression remove text or form fields?
No. Text contents, form data, links, and bookmark structures remain fully functional.
What is the maximum upload file size?
You can upload a single document up to 50 MB.
Can I compress password-protected PDF files?
Encrypted PDFs must be unlocked before compression so that document streams can be optimized.
