Free Scientific Figure Checker

A figure checker inspects measurable image properties before publication or printing.

Check a PNG, JPEG or WebP in your browser before placing it in a manuscript, thesis or poster. The figure checker reads pixel dimensions and compares effective resolution with the target at your chosen print width. It also reports the image properties the tool can actually inspect, including transparency where available. Each result separates measured values from unknown properties. Keep the report with your export and compare the measurements with the current requirements of the publication you are preparing.

  • Read real pixel dimensions
  • Check resolution at print size
  • Inspect supported properties
  • Keep a check report

Scientific Figure Checker · Features

The figure checker combines these steps in one workflow.

Read real pixel dimensions

Choose a local image to read its width and height without sending it to a server.

  • Read real pixel dimensions
  • Choose an example and adapt it to your task.
  • Start with your own input and inspect the result before exporting.
Try the tool

Check resolution at print size

Set the intended physical width and target DPI; the same pixels have a different effective DPI at another width.

  • Check resolution at print size
  • Choose an example and adapt it to your task.
  • Start with your own input and inspect the result before exporting.

Inspect supported properties

Read the format and transparency result the browser can determine. Unsupported properties remain unknown.

  • Inspect supported properties
  • Choose an example and adapt it to your task.
  • Start with your own input and inspect the result before exporting.

Keep a check report

Save the measured values and settings with your figure so the check can be repeated after another export.

  • Keep a check report
  • Choose an example and adapt it to your task.
  • Start with your own input and inspect the result before exporting.

Scientific Figure Checker · How it works

Select an image, set the print width and DPI target, review the measurements and save the JSON report.

  1. Read real pixel dimensions

    Choose a local image to read its width and height without sending it to a server.

  2. Check resolution at print size

    Set the intended physical width and target DPI; the same pixels have a different effective DPI at another width.

  3. Inspect supported properties

    Read the format and transparency result the browser can determine. Unsupported properties remain unknown.

  4. Keep a check report

    Save the measured values and settings with your figure so the check can be repeated after another export.

Scientific Figure Checker · Uses

Choose an example and adapt it to your task.

2400 × 1600 px at 85 mm: 717 effective DPI

Journal submission

Check the exported image at the width specified by the journal before attaching the final file.

Explore this example
1200 × 800 px at 174 mm: 175 DPI, below the 300 DPI target

Thesis preparation

Compare figures at the text width used by the thesis template and re-export those below target.

Explore this example
4000 × 2667 px at 800 mm: 127 DPI, below the 150 DPI target

Conference posters

Use the panel's printed width rather than the size displayed on a laptop.

Transparent diagrams

Inspect transparency before placing a diagram on a colored slide or poster background.

Revision requests

Compare a replacement image with the same print width and target used for the previous version.

Team handover

Include a report of measured properties alongside the source file and exported figure.

Scientific Figure Checker · Research scenarios

The manuscript figures came from several different export workflows. I used the figure checker to compare pixel dimensions and effective DPI at the intended print widths. Keeping the JSON reports with the files made the handover more organized, because I could point to a measured resolution instead of simply saying an image looked soft.
