Frequently asked questions

Will my PDF upload be accepted by SSC CGL, UPSC, and NTA?
Yes. Most portals enforce strict file size ranges (such as 'Between 50KB and 100KB' or 'Max 200KB'). Our tool ensures the output strictly complies with the portal boundary.
Why do other PDF compressors fail the file size requirement?
Generic compressors only offer broad 'Low, Medium, High' options which often yield sizes like 104 KB when the portal allows only 100 KB. DocMatePDF targets your exact byte limit.
Are my educational certificates uploaded to any server?
No. All compression and rendering runs entirely inside your web browser. No document or data is ever sent to our servers.
How are my activity logs saved while maintaining privacy?
By default, your Activity History is saved locally on your device only. If you choose to enable Cloud Sync, records are encrypted and tied strictly to your account.
