Private by design
Your files are opened and processed by your browser on this device. They are never uploaded to openWorkstand or anyone else, so the Resize Image is safe for contracts, IDs, photos and work documents, and it keeps working offline once the page has loaded. How local processing works
Good to know
- Enlarging a small image cannot add detail; it will look softer.
When to use the Resize Image
- Make a profile picture the exact size a website asks for.
- Resize product photos for an online store.
- Create a YouTube thumbnail at 1280 × 720.
Examples
A hero image for a website
Resize by pixels to the width your layout uses, for example 1920, with the height following automatically. Then run it through Compress Image to make the file lighter.
A passport or visa photo
The Passport 2×2 in preset gives a 600 × 600 pixel square. Rules differ by country, so check the required size and background before you submit.
Troubleshooting
The file does not open
Check that it is one of the supported formats above and opens in another app. Damaged files and password-protected PDFs cannot be read until they are repaired or unlocked.
It is slow or stops on a very large file
Everything runs on your device, so speed depends on its memory. Close other tabs, use a computer rather than a phone, or split the file into smaller parts first.
The download did not start
Look for your browser’s download bar or icon. Some browsers ask once before a site may download files; allow it and click the button again.
Frequently asked questions
Are my files uploaded?
No. Your files are processed on your own device by your browser. They never leave your computer or phone, and there is no file size limit other than your device’s memory.
Is it really free?
Yes. There is no sign-up, no watermark, no daily limit and no paid plan. openWorkstand is paid for by a few ads on its public pages.
