7 evidence-based answers
Is jopdf-win_installer.exe safe?
Evidence-based answer
jopdf-win_installer.exe appears safe. 0 of 73 antivirus engines flagged it. It carries a verified digital signature from Chengdu Lightspeed Gravity Technology Co.. Install it only when it came from the developer's official site or an official app store.
What is jopdf-win_installer.exe?
Evidence-based answer
jopdf-win_installer.exe is a software installer, about 1.3 MB. Our analysis did not identify a verdict-driving threat signal. It carries a verified digital signature from Chengdu Lightspeed Gravity Technology Co.. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
How many antivirus engines detected jopdf-win_installer.exe?
Evidence-based answer
None — 0 of 73 antivirus engines flagged jopdf-win_installer.exe. That's reassuring, though it is not proof that a file is safe, so we also weigh its behaviour, identity, and reputation.
Is jopdf-win_installer.exe digitally signed?
Evidence-based answer
Yes — jopdf-win_installer.exe carries a valid digital signature from Chengdu Lightspeed Gravity Technology Co., which confirms the file hasn't been tampered with since that publisher signed it. A valid signature is a positive signal, but note that malware is occasionally signed with stolen or abused certificates, so it isn't proof of safety on its own.
What is the SHA-256 hash of jopdf-win_installer.exe?
Evidence-based answer
The SHA-256 hash of jopdf-win_installer.exe is 8b7efdd526ffe15241d41ed4f50165223d2be34a85873e63711f65d952b0fe05, and its MD5 is 4a063f5465afae12ebecca3f414a3177. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
Is it safe to install jopdf-win_installer.exe?
Evidence-based answer
Based on the recorded evidence, jopdf-win_installer.exe has a low observed risk and is properly signed. The important caveat is source: make sure you downloaded it from the official website or a trusted store, because attackers sometimes distribute malware-laced copies under a legitimate file's name. If your own antivirus flags it, verify the source and the exact hash before overriding the warning.
How up to date is this analysis of jopdf-win_installer.exe?
Evidence-based answer
This report reflects the scan run on July 10, 2026. Because a file's hash never changes, the identity of jopdf-win_installer.exe is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
