Dummy Image is a free online PaperStack tool for image tools. Generate a dummy PNG, JPEG, or WebP of any pixel size in your browser — then copy a data URL for <img src>.
Dummy Image draws a placeholder on a canvas in your tab. Set width, height, and format, optionally pick colors or a checkerboard, download the file, and copy an embed URL. Nothing is uploaded.
You can use it on a phone, tablet, or computer. There is no sign-up, and processing runs in your browser so files and text are not uploaded to PaperStack for storage.
How Dummy Image is useful
Layouts, CMS uploads, and QA checks need a known image without hunting stock photos. Generating locally means you get exactly 1920×1080 or 1×1 in one click.
Typical reasons people open this tool:
- Finish a one-off job without installing desktop software
- Keep documents and copy on the device they already use
- Move faster than emailing a file to themselves or waiting on IT
- Pair it with other Image Tools on PaperStack in the same sitting

Practical tips
- Use PNG when you need a sharp size label.
- Very large images (over 8K) can slow the tab — start smaller if it stalls.
- The Image URL is a data URL; huge files make a long string.
Why use PaperStack for this
Many “free converters” ask you to upload a file to a server you do not control. PaperStack is built around browser-side processing: you open the page, do the work, and download or copy the result. That is the difference when the file is a payslip, a contract, a customer CSV, or a draft that is not public yet.
You also get a consistent layout across PDF, Word, image, CSV, and text tools, so the next job does not require learning a new app.
Frequently asked questions
Is Dummy Image free?
Yes. You can use it without creating an account or paying a subscription.
Are my files uploaded?
No. Processing runs locally in your browser. PaperStack does not need your file on a server to run the tool.
Does it work on mobile?
Yes. Use a modern mobile or desktop browser. Very large files are more comfortable on a laptop because they use more memory.
Can beginners use it?
Yes. Follow the steps above. If something looks wrong, keep the original file and try a milder setting (for example less compression).
