Image Mockup Generator: beginner's step-by-step guide
No prior knowledge required. Six steps with Image Mockup Generator and you're done — runs entirely in your browser, no signup, no app.
If this is the first time you've tried to mock up a image, the jargon is more intimidating than the task itself. Compression, encoding, codec, DPI — most of it doesn't matter for what you actually want to do. This guide walks through Image Mockup Generator step-by-step, no prerequisites assumed.
Launch the tool: Image Mockup Generator — Free, no account required, no watermark.
Step 1: Open the tool
Go to Image Mockup Generator in any browser — Chrome, Safari, Firefox, Edge, all work. You don't need to sign up, download an app, or create an account.
Step 2: Add your image
You can either drag your image from your desktop into the dotted-line box on the page, or click "Choose file" to pick it from a file dialog. Both work the same.
Step 3: Wait briefly
Your image loads into the browser. This takes a couple of seconds depending on size. It's not "uploading" — there's no progress bar to a server. It's just preparing the file for processing.
Step 4: Adjust the settings (or don't)
Image Mockup Generator ships with sensible defaults. If you don't know what an option means, leave it alone. The default for any setting is what most people want for most images.
Step 5: Click Run
The button might say "Compress," "Convert," "Process," or something specific to the tool. Click it. Watch the progress indicator.
Step 6: Download the result
When processing finishes, a "Download" button appears. Click it, and the result lands in your default downloads folder, named after the original (usually with a suffix).
Launch the tool
Runs entirely on your device using open web standards.
What if something looks weird
Common first-time confusion:
- "It says the file is loaded but nothing happened." Click Run. The tool waits for you to start.
- "The button is grayed out." You probably haven't added a image yet, or the format isn't supported. Check the file extension.
- "The result looks the same size." That can happen with already-compressed images. Try the aggressive preset, or accept that there isn't much more to save.
- "I can't find the downloaded file." Browsers default to a Downloads folder. On Mac it's
~/Downloads; on Windows it'sC:\Users\YourName\Downloads.
Frequently asked questions
What if I'm using a school or work computer?
Image Mockup Generator works through any modern web browser. It doesn't require installing software or admin privileges.
Do I need to install anything?

Can I undo a mistake?
If you keep your original image (highly recommended), the worst case is you delete the result and try again with different settings.
