Is Image Mockup Generator safe for sensitive images?
The honest answer on what happens to your image inside Image Mockup Generator — and why "no upload, no account" matters for sensitive files.
If you've ended up here, you have a image and a specific job: sensitive content. The defaults most software ships with aren't tuned for that — they're tuned for "archive everything at maximum quality," which is the opposite of what you need now.

Why sensitive content needs different settings
A image for sensitive content optimises for things the original image doesn't care about: small enough to upload quickly, compatible with whatever software the recipient is using, and free of embedded metadata that could leak personal information. The defaults give you the opposite — large, high-quality, metadata-rich. Useful for some jobs, wrong for this one.

Recommended settings for sensitive content
Run it in your browser
Browser-only. Nothing is sent to a server.
What to verify before sending
Quick check-list once Image Mockup Generator finishes:
- Open the result. Make sure it looks right at the size the recipient will actually see it.
- Check the file size. Match it against the limit you're targeting.
- Confirm the file extension. Sometimes you need to rename — for example, a recipient who expects
.jpgwon't necessarily accept.jpeg. - Send a test to yourself first. Open the test on the same device the recipient will use, if you can.
Frequently asked questions
Will Image Mockup Generator work for a batch of images?
Yes — drop multiple files at once. All of them get the same sensitive content settings applied, then downloaded as a folder.
Is Image Mockup Generator safe for sensitive images like a resume or visa documents?
Yes — every step happens locally in your browser. The image never leaves your device because there is no server in the loop.
Does compressing a image make it look unprofessional for sensitive content?
Not when done right. Sensible compression at the "balanced" preset produces output indistinguishable from the original to the human eye, even at half the size.
Can I undo the compression later?
No — compression is one-way. Always keep the original image archived somewhere, and treat the compressed version as a send-only copy.
