Three clear steps
How it works
- 1
Select your original photo or graphic.
- 2
Workbox checks whether it already passes before changing anything.
- 3
If needed, the browser optimizes the image and confirms the final file is no larger than 1MB.
Why a file can exceed 1MB
High-resolution phone cameras record millions of pixels and additional metadata. A single photo can easily reach 5–15MB.
Upload forms care about the encoded file size. Workbox checks that real value and avoids changing an image that already satisfies the requirement.
Tips for a reliable upload
- If the destination accepts JPG, it is usually efficient for camera photos.
- Mention maximum dimensions when the portal provides them; fewer unnecessary pixels mean a cleaner result.
- Keep the page open until the download finishes because processing stays in the browser.
Frequently asked questions
Is 1MB the same as 1000KB?
Workbox uses the common binary conversion for file limits: 1MB equals 1024KB.
Will an image already under 1MB be changed?
If it already meets every requirement in the box, Workbox keeps the original file data and simply validates it.
Where is the image processed?
On your device, in the current browser tab.
