Get a photo or signature ready for an upload form in one place. Set the required width, height, and file-size limit without stretching the image. Review the final JPG before submitting it.
Free to use / Runs on your device / No account neededDimensions remain exactly as entered. 1 KB = 1,000 bytes. Presets are starting points, not official requirements. Check the current form: some require a live photo, minimum file size, specific dimensions, or a different background. This tool does not verify identity or guarantee acceptance. Maximum input: 25 MB / 40 megapixels.
Your prepared JPG appears here. Check the entire image is readable before using it.
How to use it
- Select a clear JPG, PNG, or WebP photo or signature.
- Enter the dimensions and maximum KB from your current form. Choose padding or adjust the crop position.
- Prepare the JPG, inspect its readability, and download it. Confirm any minimum-size or live-photo rules separately.
A few useful answers
Are the presets official passport or exam requirements?
No. They are starting dimensions only. Requirements vary by application and year; some forms require a live photograph and do not accept an existing image. Follow the instructions on the actual form.
Will the dimensions change to meet the KB limit?
No. This formatter keeps your chosen pixel dimensions and adjusts JPG quality. If the target is impossible at those dimensions, it reports that instead of producing an oversized or stretched file.
