About this app

PreviewMaker helps you to put watermarks on a lot of photos. You can use multiple templates (like „do not copy“ stamps or a „sample“ background-writing), chose size and position where the watermark should appear, and even edit color temperature, hue, brightness and contrast.

How to install this safely

How to verify the file you downloaded

Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.

What the signing certificate proves

Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be com.tistory.deque.previewmaker is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.

How to roll back to an earlier version

No earlier build is on record for PreviewMaker, so there is nothing to roll back to yet. When a second version is published, this section will explain how to move between them safely.

Why we list sources instead of hosting everything

The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of PreviewMaker, and a listing is removed when the evidence for it stops holding up.
