Frequently asked questions
Will the portal accept it?
The output is a standard JPG at exactly the requested pixel size and within the KB range, which is what upload forms check automatically. Always confirm the current requirements in your exam or job notification, since they change.
Why is my file a bit bigger than I expected?
If an image compresses below the minimum size, a harmless blank comment is added to the JPG file so it meets the minimum. The picture itself is unchanged.
Is the Thumb Impression Resizer free?
Yes. The Thumb Impression Resizer is completely free with no sign-up, no watermarks, no daily limits and no premium tier.
Are my files uploaded to a server?
No. FileStripe processes your files locally in your web browser using JavaScript. Nothing is uploaded, so the Thumb Impression Resizer is safe for private photos and confidential documents and even works offline once the page has loaded.
Does it work on iPhone and Android?
Yes. The Thumb Impression Resizer works in Safari, Chrome, Firefox, Edge and Samsung Internet on phones, tablets and computers. On a phone you can pick files from your photo library or files app and share the result straight to another app.
