fact_checkPre-Upload Checker

Check your photo before you submit it

Compare format, file size, dimensions, and aspect ratio against a requirement-focused preset. The check runs locally and never guarantees destination acceptance.

This is a mechanical pre-upload check. It cannot inspect facial framing, identity, background quality, or guarantee acceptance.

check_circleWhat this tool checks

  • Readable image signature and supported browser format
  • Requested pixel dimensions, output MIME type, and output integrity
  • Requested byte ceiling when the compression workflow can reach it

infoWhat this tool does not check

  • Whether a destination website will accept the image
  • Face position, expression, lighting, background, or document-specific rules
  • Whether a platform has changed its requirements since the listed review date

lightbulbBest Practices for Best Results

  • checkAlways start from the original camera capture rather than a WhatsApp or social media copy.
  • checkLock your aspect ratio when resizing unless you are intentionally reframing with the cropper.
  • checkSelect JPEG (.jpg) for realistic photographs and portrait headshots; use PNG for logos and text.
  • checkCross-check your destination's required pixel dimensions and KB limits on our Global Platform Presets before final submission.

troubleshootTroubleshooting & Common Solutions

help_outlineMy resized photo appears blurry or pixelated

Blurriness occurs when enlarging a small image beyond its original pixel dimensions. Always start from the original high-resolution camera photo rather than a screenshot or compressed social media copy.

help_outlineThe upload portal says my file size is still too large

Use our KB-limit compressor to set the portal's maximum byte ceiling (e.g., 50 KB, 100 KB, or 240 KB). The iterative engine searches for the highest practical quality that stays under that ceiling.

help_outlineMy photo looks stretched or distorted after resizing

Keep the aspect ratio lock enabled during resizing. If your original photo has a different aspect ratio than the destination requirement, use our Image Cropper first to frame the subject before changing dimensions.

help_outlineThe destination website rejected my file format

Most government and university portals strictly require JPEG (.jpg) files. If your file is a PNG or WebP, use our Image Format Converter to transcode it into a standard sRGB JPEG in one click.

Frequently Asked Questions

Does a pass guarantee acceptance?

No. This checker verifies mechanical properties only. It cannot judge identity, facial framing, lighting, background, or destination-specific rules.

Are my photos uploaded?

No. The file is read and decoded by your browser. No image upload endpoint is used.
