Up to 20 MB, 24 megapixels and 8,000 pixels per side. You can also drop a file on this panel.

SMALL STEPS. SMALLER FILES.

Done in three steps.

  1. 01

    Choose your image

    Use the clearest original you have. JPG, PNG and WebP work here.

  2. 02

    Set your limits

    Pick a maximum KB size. Add exact pixels only if you need them.

  3. 03

    Read the check results

    Review each requirement separately. Fix only the settings that failed.

GOOD TO KNOW

Get a better result.

Enter only the requirements your form actually gives. The checker compares the original file, not a recompressed preview, and lets you select decimal KB or binary KiB.

Passing these technical checks does not assess face visibility, background, signature authenticity, document validity or live-capture requirements.

A few useful answers.

Are my images uploaded?+

No. Image processing happens on your device using your browser. Closing the tab releases the working image. Downloads remain wherever your browser saves them.

Will this meet every upload requirement?+

It can adjust pixels, format and file size. A portal can also check background, face position, document validity, minimum size or require live capture. Read those requirements separately.

Why did the image get smaller in pixels?+

A very small KB limit may need smaller dimensions after quality compression. Enter exact dimensions to keep them fixed; if the size limit is impossible, you will see an error instead of a misleading success.
